Acids, Bases, and Salts Overview

Who is your path Who got the chance to stop this When the mountain's feet are uprooted from its authority you fill up with a roar [music] [music] Hey Guy Wake has the largest and the most The Impactful Lingering Platform That Is Physics Valla is all my dear ones Brothers and sisters if you can see me If you can hear me then comment once will you write it quickly in the section All the dear brothers and sisters I will write Bharat Mata ki Jai in the comment I will quickly write Bharat Mata ki once Jai our beloved mother Bharat Maa ki Jai in two the comment section if you guys can see me you are standing and can hear me my love Son Sunil aka your loving Sunil brother who is standing here in front of you and will teach you about acids, bases and salts in One shot will be really fun, what do you think what's the matter what's the matter what's the matter Divya Manendra Jeevika Siddhi Reality little kid archana ivan rahul puja dil se you are all welcome my dear Dear little brothers and sisters of India The biggest and best platform But today we are going to the one whose name is Physics wala Will finish it off nicely in one shot The chapter is titled Acids Bases and Salts is okay I will finish it off I will make you do it, you will be able to make every question by yourself I guarantee this thing, okay? This is very good brother, what else will you read Sunil Bhaiya please tell me quickly first of all You will read a discussion about physical properties We will talk about assets and bases again Classification of Assets and Bases Chemicals Properties of Assets and Bases Introduction to the pH and the pH Scale What will happen after that Sunil Bhaiya my friend Salts and its types, its nature and last How are salts made in All those things, from A to Z, everything to you Everything will come apart from that You will get previous year questions and official Compton Focused Questions I'll end it all It's ok inside this class Sunil Bhaiya let's start then let's start with the very first thing that is the physical Properties of Assets and Basis Physical Properties means physical properties, which properties hey raja son physical Qualities like Sunil bhaiya what are your physical qualities Look, Sunil, you are of marriageable age. If it is brother's then he is of marriageable age now So our CV goes so CV What actually happened to you Sunil Bhaiya? Brother discuss about my physical qualities It happens that Bhai sahab our son is 5 feet 11 Our boy is of inch size and is wheatish in colour Colour and our boy weighs 64 kg looks malnourished weighs 64 kg yes that boy has very good bone density Jhad used to do karate, good good good well very good very good so this is all What are all these physical properties of mine? I have physical qualities, now if such discussion is About your resume assets and bases If you discuss then it becomes physical Understand the Properties of Assets and Bases No Do you understand what is the matter, what is the matter sir revision When will the classes start very soon Look friend, my course is over. Teachers will be finished if it happens to everyone If it is gone then we will start revision from that time itself We will start the classes in batches, ok ok bhaiya it's alright so look here The first question is for you guys Acids R always found in the liquid state at room Temperature means room temperature which is 25 degree celsius is dependent on it all our Acids are in the liquid state, that is are in liquid state now this is true or is it false to me Tell me my question is very simple acid means that Acids Are all your acids at room temperature? At 25°C, what is the hey brother you are in liquid state why should it be warm well my hands are cold It's cold and my hands are cold The water feels hot yes ok b a and b a and B A and B so look at this carefully correct answer what do we have be that is False means all acids at room temperature if not in liquid state Then look carefully at the first thing Physical state of some acids are found in the solid State while others are found in the liquid state at room temperature i.e. some acid This means that the acid remains solid at room temperature. We find them in the solid state and some acids are in liquid state see you it's a very simple thing Go to the market and find a shop for dandruff treatment Boric acid name in market The acid is found in those who use it to remove dandruff Everyone will know that I apply it on my hair The powder is white in color in solid state Go and see what is available in the market Do you understand then which state are all these acids Like boric acid became oxalic acid became tattic acid became citric acid has happened, phosphoric acid has happened to me Friend, all of these are solid state to you that is, they are found in solid state Which states are found in the solid state? what's the matter brother it's fun Similarly if we discuss here acetic acid formic acid Carboniferous Id Nitric Acid Sulfuric All of these acids are in liquid state Sulfuric acid is also present in liquid state All of us in liquid state Which category do you get all of them in? These are acids, all of them are liquid acids acetic formic carboniferous sulfuric ye Wow, you can find it in all liquid states Bhaiya it was fun, one more extra in this points and I will remember what should I remember my Dear Sunil Bhaiya, my dear elder brother What do you want to remember? Listen to me carefully, Rani with my attention Listen carefully king, son and queen, daughter Will you listen brother volatile acids vaporize easily that is at room temperature and on heating about and on heating at about 100 degrees Celsius so this is the category we have Front All these acids are liquid It is in the state but is volatile meaning that they have low boiling point and they evaporate quickly but one you you are in a wide state and at the same time it's non volatile which one is it's it's it Sulfuric In the acid study of compounds we read this that was also why we call sulfuric acid prefer for the formation of others gases rather than these acids because these It is non-volatile in its own vapor convert but it doesn't happen easily You will remember this Sunil Bhaiya, now look at this There was a question on this in ICSE 2022 The acid which is least volatile has arrived Raja beta will tell you soon in a jiffy I will answer it in just a snap I will tell you the answer soon I will tell you the answer soon I will tell you the answer quickly, this is basically Also remember which one is concentrated Also remember that it was concentrated and not diluted I have to keep it, is it okay or not? We are not Talking about the dilute we are talking about the concentrated one so what is the answer is concentrated sulphuric Acid Remember Keep water also inside the diluted one Now the water can be easily vaporized So the more water there is the lesser and acidic the greater the quantity We are talking about sulfuric acid. That means look at sulfuric acid. concentrated that is a non volatile acid So this is asking what is the best of all these Which is the least volatile? The least volatile that the least you can say is yours has the lowest tendency to be vapers It can be converted easily brother, this will also happen this will also happen this will also happen but its which has the tendency to convert into vapors that it is the least volatile Concentrated Sulphuric Aid Clear Baat G Bhaiya will go ahead to play my king concept baja come son come second Is test third is corrosive nature now test I mean if I test the acid I should do an understanding test like for example this is it now I am saying that I need to test it If you want to do it then what is the meaning of doing the test It came out like this and test this test has been done you are tasty you are good you are very tasty you are very Great, now look, a misconception happens All the acids are also written in books They're sour oh how can they all be sour If all the acids are sour then they are present in the house coffee powder is called coffee powder Coffee is bitter if you put it on your tongue Powder If all acids are sour then my Brother Do one thing, go home and get some coffee Open the box, take out the coffee and like this Taste it on your tongue, why is it bitter Hey, coffee is acidic, but still If it is bitter then acid has no relation with taste There is no relation, we can say this to understand Because majorly the acids are sour but all the My king did not understand this, so he said to General Acid test sour i.e. most of the acids Our sourdough yes it is right but they can taste bitter as well as Sweet means acids are our bitter and sweet Both can be acids, our bitter and Our It can be both sweet and bitter Are you able to understand it or not? The test of acids is generally but it can be bitter and sweet like for Example: Amano acids are bitter and sour It is also sweet in the same way as the acids present in coffee There is caffeic acid and conic acid which are bitter Would The acid present in other things is also sour It is possible, so that is why we say that Generally speaking, most of the cases are sour but they can be bitter or sweet too Corrosive Now look at nature, now I will tell you about mineral acids I will tell you a few things about minerals What are acids which are called inof nic They are called acids so right now you can just know the names Remember that these are organic or mineral Acids Now I will tell you further that these What are inophenic acids or minerals Acids generally mean most of the cases All the mineral acids present in it It is corrosive and it can cause pain Burns if fallen on the skin means so many it is more serious and dangerous that if your If it comes in contact with your skin, your Burns can cause permanent damage to the skin You can give you pain so are very dangerous and some ruthless people when Some people do acid attacks, some are very mean And you can say that he is a very bad person what happens when an acid attack takes place You will know that it is on the face or the body If you throw it anywhere, you will get permanent burns There is permanent damage to the skin no i have strength he is No, Sunil Bhaiya Now let us discuss the basis a little bit I hope I understand so many things I am understanding all the small things it is clear right let's go okay let's go one minute one minute minute one second one second a little something Give fun to people inside the chat box give it a second inside So now let's move on quickly If we talk a little about the basis here Let's discuss if we are talking about the bass so what do we have the bass what are you, please understand carefully what are bases bases which are these are the substances C H R Bitter In Taste means this is that substance which are bitter, right? What is the test that is basically done These are bitter then bases means that basically we have shar and jo Shars are what they are basically bitter are the curses which are there, that is The bases are bitter, so The test of Bases is that this They are bitter, okay, the first thing is the concept Our number one is done, that means The base ones are bitter this is concept number two have you ever seen these have you ever touched substances This substances such as for example i am going to tell you let me tell you have you ever used washing soda Or caustic soda for washing all these things Soda, caustic soda, have you ever touched these? if you have ever touched them then If you touch them then whatever they have Has a soapy texture that is they are slippery what does two touch mean if you If you touch it you will feel as if you have touched someone Touched soap has absolutely slippery texture It means that after touching them you will feel like this it seems hey this one is slipping I am slipping because in actual Your hands make soap because What's inside the skin on your hands? If I go into more depth then there will be fatty If you come in contact with acid base Basically, actually making soap if it happens then they have a soapy texture that means they are very very slippery to touch ok yes sunil brother let's go after that if we go here But if we know a little more about Baseus Physical Properties of Acids We Are three things we knew we are done with Physical Properties of This Now Basis If you know about taste and texture I just told you about their test. Basically their texture is bitter It is basically soapy, you will remember it on the other side let's go to which nature corrosive nature now which When we touch these types of acids There are some acids which if touched If our bodies come in contact then we will can burn or damage the same type some bases which we also have Der and some bases are basically corrosive we are corrosive na so some bases like sodium hydroxide and potassium Hydroxide Produces a burning sensation on the skin so it is advisable not to touch and test ten Basic substances like acids are corrosive in the same way some bass are so much It is corrosive because if our skin If it comes in contact it can burn You can burn it, you can damage it Taste is bitter, soapy texture is damaging i.e. corrosive nature it is only after we understand this much Sunil Bhaiya, now we understand this Should I touch or test them? what do you think what do you think The answer is already written on the simple board but you what do you think what is your perspective on this what is your perspective on this tell me quickly what is your Perspective on this to identification I will tell you that I am taking a side so you can tell me the correct I will tell you the answer soon what do you think no no no no what's the matter what's the matter what's the matter this yes person is which brother is he where is he studying where are you studying come on a minute getting a Call done where are you studying brother either you he is not studying at all, he is just saying yes sir so tasty Who is it You are logged out bro what are you doing You have logged in or out from here Do not log out your account in the middle of a class Do it friend, let's do identification if I test something or if If I touch something, will it be a do we have the right way if not then see, test it now it is very There is a misconception in people's minds that if If it is acid then it is sour and if it is base then it is bitter It is and I will test it and find out This is the most stupid thing to do now what about this thing I will tell you what are the disadvantages well other people feel that by touching also we can tell why because basis the texture of is so when we touch them How do we like the soapy texture, that is When we touch them it feels as if Soap in our hands If so, both these things are wrong, what is the reason now listen carefully you are not both of them can you can't do both these things reason Because this can be a disaster for you This could be fatal for you, now this is our Why it can be fatal or cause disasters Because some acids and bases can affect your health highly are corrosive that is they produce a Burning sensation on the skin and can cause damage it some acids and bases so much Is corrosive that comes in contact with your skin If you come then brother your skin will be affected Can cause permanent damage and can burn will damage it permanently after that why would you do this Sunil Bhaiya I will taste it sour If it is there I will call it acid, if it is bitter then call it base or basically I will tell you its texture am I touching it to do it or test it I am doing it my brother if it gets corrosive then your tongue or hand is missing and secondly is this a reliable method hey brother the test of acids is It can be bitter, it can be sour, it can be sweet Maybe then testing is not a relief Option means you are dependent on the test why only yes how can you tell by testing someone that the thing is acid and base because it I guess there's no right way You are blindfolded and given coffee did you taste test? did you taste test the coffee? Sunil bhaiya said if the coffee is bitter then what are you doing You will say that this is base but that is acidic Coffee contains quinic acid and caffeic acid because of which it is bitter so firstly The taste of acids can also be bitter It can be sour as well as sweet If possible then testing is a reliable option only no there is no reliable option, it is not a good value If this thing is not there then I am talking about texture Through this I will find out what kind of soapy texture it is The base is gone, brother, your skin will burn If you go then don't do these things then what should I do brother what should I do if If you want to find out whether something is an acid or a base How do I find out, my brother you will find out From whom will you learn chemistry? using so there are some chemical substances i.e that there are some chemicals here that show a sharp change either in colour either basically in order in the The Acidic and The Basic So if I want to find out the medium, Sunil Bhaiya, if something is an acid or a base then So I can test it, I can touch it I can neither taste nor touch neither taste nor touch nor taste nor touch then what can i do So brother, I am a chemical substance some chemical can be used a substance which is either different in color or Make changes to your order in acidic and basic medium and we call these what do we call these we call acids Base indicators are of two categories of indicators You should also remember some indicator colors and some indicators Changes in order bring their own color Yes, we will bring changes like a chameleon yes it changes just like your life I have some friends, some whom you They change their color thinking they are their friend No, just like something comes in the chat box Some chat boxes come in their own colors to show off your sanskaar Similarly, chameleons take two forms of spam Come to do it inside the comment section don't have kids And these are the children living in small villages Meaning there would be people who are looking for employment they are there then what do they get 50 they come and spam or are they telecallers of the company doing the work of and then making your karma worse If you are doing it then stop telecalling also. You will go a little higher in life get up did you understand yes I said it indirectly I understood what I had to understand, now let's move ahead Let's go and spam my class nothing will happen first come down to my level Then spam it now see this level The difference is that you sit on the other side of the screen I'm typing and I'm standing here when you If you come here then the level will be equal, understand went running away There are some chemicals that which brings a sharp change in their color or bring a change in your smell and They tell us that brother this is acid, brother this is base if so, we call them acid-base Now watch the indicator change color The indicators that we are going to bring Some common indicators are discussed here we will do whatever we have as if it were the best If we talk about these three first, then this What we have are natural indicators this is what we have these are the natural Indicators and this is what we have these are basically Synthetic Indicators Synthetic Indie caterers okay so the first thing we have hai litmus solution turmeric paste Hydrangea Flowers Phenolphenyl Methyl We have these orange indicators now. Look at the color of litmus in neutral solution What is litmus in neutral solution The color is pale purple or basically its There is colour It is a mauve colour and turns into acid red and blue become the same in bases If we talk about turmeric then Turmeric, that is, turmeric is neutral It is yellow in acid and red in acid What color is it in base it goes into the base basically What color does brick red become? Red then Hydrangea Flowers Lots These flowers are a cool thing Hydrangea Flowers The Soil It Grows In About the pH or nature of that soil I will tell you that suppose the soil How do we know if it is acidic or basic? The flower of this petal is based on its color you will know, for example, if it is blue What does it mean find out the nature of soil you will find out the nature of soil if your soil is if we assume what is its nature Is the nature of soil neutral or acidic? Acidic and Neutral acidic or neutral is fine Is it is either neutral or acidic Its flowers will be blue in colour But if the soil is basic then Its flowers will be basically pink What will be the color, very good understanding I am getting to the point where I am Phenophenly Indicator is synthetic meaning which we have This synthetic material was created in a laboratory Indicators are basically what they are Natural indicators are litmus, turmeric and Hydrangea flowers are basically the Natural Indicators Phenol and Methyl Orange R Basically the Synthetic Indicators Now Synthetic indicators are those which Made in a laboratory as for example we have it finally we have it Colorless We also have neutral and acidic It is colorless and basic, we have it This is pink If we talk about type methyl orange In neutral we have orange In acidic we have red and what do we have in basic Yellow Orange Red Yellow Colorless Colorless Pink blue blue pink yellow yellow brick red pe Pale Purple Mauve or Pale Purple or Mauve Red and blue these colors are done so their change in colour with the help of You will be able to tell that there is no medium here is it acidic, basic, or neutral What a thing Sunil Bhaiya it's very nice, it's fun it's fun it's fun let's go We will solve all the questions quickly all my dear dear friends dear brother and sister to here we go soon sooner than can be detected by the change in colour It will be quickly identified by the change in colour will it be acidic or basic It is neutral as if it has been given chuch off here The Following Observation Correctly Shows the Action of sodium hydroxide solution on the Now let's consider a particular indicator as sodium. is the hydroxide solution and assume I put methyl orange in a beaker and I have sodium hydroxide in the beaker Added methyl range to the second beaker as well Sodium hydroxide is the phenol to the drops Poured two beakers, both containing sodium hydroxide we need to confirm that sodium hydroxide is How will you confirm, suppose I told you He said, son, there is sodium in both these beakers. Hydroxide is a colorless solution of How to confirm if it is sodium hydroxide You put methyl orange in one In the second you fin How to know inserted It will seem so, let's see the correct answer Its will come to us see very good very Fantastic PW lad Monira Amarth aditi amrit tashu aksal legend daksh madhav Iti Yadav Sangram friend all the children About 800 children participated live I am sitting with all the kids I would request that all of you Very few children participate Let's participate but let's talk about it no now look at sodium hydroxide that is that caustic soda it is nothing but a base it is nothing but a Now what is the colour of methyl orange in base It is yellow, look at this, methyl What is yellow in the color base of orange Would and secondly what is the colour of fino If it is pink then it means sodium It will turn pink inside the hydroxide You should remember pink and yellow, right? ok let me tell you one more thing about your ICSC This red one is also pinkish red they also call this age pinkish red Or if it's only red then you can remember both of them will keep methyl orange pinkish in acidic Red or Red both will remember this coming to the question So brother it is in methyl orange yellow It will change very well, it will definitely it's right it's colorless it's wrong it's orange too Not pink, not colorless, orange to yellow What's absolutely correct Colorless to Pink this is also correct this is also correct correct answer We have C so this is official Compton This year's question was focused, let's move ahead let's go now look here we have some Indicators come in their own smell brings changes i.e. in the order Sunil Bhai, these indicators bring change what is the need of See which changes are made in the order first Let's bring them here, we call them all Factory indicators which indicators We call them all factory indicators We tell them, well, what a thing, very good and what is the need for these this is Helpful for Helpful for Visually Impaired people means those people who cannot see Can this be done for visually impaired people Necessary These are the indicators which are present in their smell Brings change in different medium and with the help of which we are able to find out whether something is acidic or basic it is called all Factory indicators speak in your nose receptor is all factory receptor that is responsible for your sense of smell No jiwiya so this is helpful for those people who Those who have less grace of God and who cannot see the world with their eyes They won't be able to see the fairy in color, oh my Brother, what are natural and synthetic indicators? Someone tells us by changing the color thing is acidic, basic, neutral now If a person cannot see, then how can he If I tell him then it will be too much for him It is beneficial that he will tell you something Is the thing acidic, basic, or neutral? what's the matter brother very good so three Indicators I tell you onion dirt cloth strips second vanilla essence and Third clove oil that was not a song oh In Lung Le There was a song like Laachi tere peeche aag vachi Na To Lung Lung Clove Clove Oil Vanilla Essence Onion Dired Cloth Strips Onion what does that mean for odd cloth strips onion slices cut onion into pieces Cut some pieces of clean cloth into a Take a ziplock packet and clean cloth pieces Add onion pieces and zip lock Close the packet and keep it in the fridge Take this packet out of the fridge and open it take out the clothes in that cloth there will be smell of onion this is called as the Onion Dirty Cloth Strips Now you have taken out two strips Onion Oder Cloth Strip Onion Oder Cloth the strip is in front of you the acid is in front of you it's base, suppose I blindfolded you tied an acidic solution kept a basic Put the onion smelling cloth in the solution You have another piece of cloth in your hand You have seen this one which has the smell of onion You dipped it in solution one I dipped them in solution B and took them out Removed this onion smelling cloth When you dipped it in Solution A you saw Then you dipped it in the water and Sanga now wherever there is, in whichever case The smell is coming from inside the clothes of the thirsty the smell of thirst is still there We had that acidic solution and The one from which the smell had disappeared was basically The basic solution was onion fragrance The cloth which was there were two cloths, one put one in acidic solution and one in basic When it was taken out of the acidic state, it was here The smell will remain and the basic one will have the smell If it flies away then the one in which the smell has flown away It is basic and the one which has smell is acidic Similarly, the smell of vanilla essence which You also put it in the solution and it smells This means you put it in acidic smell It has flown away, it means you put it in the basic in the same way as the smell of clove oil It will still come from a particular solution Acidic and it has blown away so basically basic is fine yes bro Yes, the smell would disappear in basic solutions They have a smell in acidic solutions remains maintained it's ok I will write to you once Brother, if you have understood the story till here I am really enjoying it so please come once brother I will tell you that Sunil Bhaiya, you have understood till here Used to be Correct Is let's go quickly very good very good very good very good This scary guy is writing this Block whoever is writing this, it's scary. Scary, bye bye this, get it done permanently block up up up up okay yes come on bye I will directly say bye bye to useless things Don't do anything son, we will go straight to the block We hit it, it doesn't make any difference, the block is gone Zenon child comes to you to study So you don't need these useless spammers In life, go wherever you want and spam Views don't come, those views don't come, they are fake Those with views come there and watch our show We get a lot of genuine views, we need them No I don't need kids like you Let us know the classification of acids and Bases Understand it now See Classification of Acids and Bases The funny thing is how do we process acids? How do you classify and read whom? We study by dividing it into types and categories Now let's understand this thing a little bit So what is the first thing that comes to us? Classification of acids on the basis of there On the basis of source On the basis of source types of acids so the first one we have is The category is that is called as the organic Acids Organic Acids where this term Organic means preserving and related to Look at life, this word organic It means whenever something affects living things It is related to that which means to the living thing If it is related then use the word there it is organic it means something is related to life something is related to Living Things ok now what are organic acids basically Organic acids are those which are Obtain from the living sources that is Plants and the Animals Now It's Early The definition is organic acids or organic of compounds that these are acids These are compounds that are responsible for the production of new substances in living things Either meet me or meet me at the plant Or do we get these older definitions from animals? What does the modern definition say? The definition says something like this modern idea this is a modern idea that Organic acids will be those that have There will be carbon and hydrogen atoms, and At least one bond would be to carbon and In between the hydrogen atoms we call them are organic acids what did i say de contain carbon and hydrogen atoms and at least a bond is present between a carbon and hydrogen atoms these will be organic acids or organic For acids to be present it is compulsory that It is compulsory to have carbon and hydrogen inside and at least one bond is between carbon and hydrogen There should be direct bonding between the This is a modern definition, this is a modern Definition is ok yes organic chemistry I have understood this thing more thoroughly I had cleared it for you but you had to do one You might have got a slight idea that the old Definition Organic means that which is alive It is related to things which are called organic so that is why we believed that the We get acids from living things What do we call those plants and We are getting it from animals and living things Organic acids are available but today The modern definition says that Carbon and Hydrogen Containing Compounds that they contain carbon and hydrogen and At least one mole of carbon hydrogen is present between If there is a bond then that means it is an organic acid and an organic compound okay let's go Now, for example, here we are talking about If you talk about citrus fruits then use citrus fruits In fruits we talk like for For example we have lemon for We have an example, it is orange, isn't it? all that we have is these Citrus Fruits Now in Citrus Fruits Mainly what we have is citric which acid is citric acid but also this is the content but they also Everyone knows that soursop contains vitamin C Things that contain vitamin C and vitamin D We also call C ascorbic acid. I told you this just for knowledge Citrus fruits such as lemons It turned orange due to major citric acid it happens c6 h87 Along with this, they also contain vitamin C may also contain what is called ascorbic acid Yes, I have understood the point Sunil Bhaiya, please come Let's move on and let's talk about tamarind or Then we can say grep it so Inside we have tartaric acid which Tartaric acid is present in tomatoes Oxalic acid vinegar has a We have a diluted form of sa form is a diluted form which we call acetic acid That is, we call it Hindi. I call it in hindi Vinegar is vinegar which means vinegar This is a diluted form of acetic acid So inside this we have acetic acid The oxalic acid inside is derived from tamarind or grape i.e. that tamarind or grapes have major tartaric acidic citrus fruits, such as lemons or Oranges contain mostly citric acid. In addition, there is also vitamin C in it There is also good ascorbic acid in them and There can be acids also but here we have Those are written which are majorly inside them It is present in large quantity After Nettle Sting Now what is Nettle Sting Nettle is basically a plant that The one which is there is sharp and it has hair on it. If it collides by mistake then it will be in your hands will you inject formic acid or which we call in simple language methane solid If acid is injected into our hand This nettle plant has this sting inside it It is acidic just like a red ant or basically a bee which also When it stings you, it is inside you too Formic acid or as we call it Methane acid is present in our body due to which we feel burning sensation and pain It happens, oh brother, there have been many, many G yes there must have been many brother this acid has entered hey brother this is in your hand Sir Apple means apple an apple a day keeps doctor away ok It is not okay Sunil Bhaiya, chemistry is addicted are you understanding the fear away yes watch a lecture by sunil bhaiya Eliminate the fear of chemistry through Apple Contains malic acid and curd Which lactic acid is present in curd Acid Lactic I named my friend Acid Yogurt curd in childhood because he used to bring curd everyday When he was in school I named him Dahi I had given him curd friend, his name was Dahi Dost okay so all these acids It is an organic acid well the acid is present in urine i.e. Which acid is present in urine are you understanding Hey brother, someone created an ID in my name very nice Son, tell me quickly, is there any acid present in urine Which substance is present in urine acid is present now see where is tannic acid it contains tannic acid which is basically our Which acid is present in tea? it is basically tannic Tannic acid is present in tea Tannic acid is present where is uric acid it is present or acid is present Where is it presented inside the urine OK G Beautilish Butter means your butter which is now spoilt it's over, it's not worth eating, the leftovers are distorted That means there is nothing left that is edible Its taste and smell is stinking bad The change has happened from inside that dirty butter which there is a smell that is because of butter acid build up due to Oleic acid is basically present in Olive oil inside olive oil if I tell you So it's basically a way of using olive oil which olive If oil is fine then olive oil is it contains this okay oleic acid Butyric acid in olive oil Rancid butter uric acid in urine and tannic acid inside Acid in tea is ok son yes yes Sunil Bhaiya Done let's now move on to the second category of acids on the What is the basis of source that we have Sunil Bhaiya, we have the second category of minerals Regarding acids, mineral acids means these We talk about nickel acids minerals acids or inof guani acids are those which are obtained from non-living sources that is rocks and minerals i.e. what we Alive are obtained from living sources Plants and animals are found in things We find organic acids which are non-living Sources include rocks and minerals Minerals are found from stones We are meeting them, we call them Inorg nic acids such as for example hydrochloric acid for example Sulfuric acid for example nitric Acid for example carbonium and more now You will say that in carbonium, hydrogen and it's carbon oh my king why is it inoff look carefully this carbon is correct this value Son oxygen this respect Son oxygen this respect son hydrogen this value son hydrogen and this value son oxygen is ok h2 co3 so What did I tell you about organic consideration? what an important thing to happen son This is an important thing: carbon and hydrogen There are atoms, but there is also a bond between them There should be a direct bonding I want something between carbon and hydrogen Because of the presence of carbon and hydrogen only There will not be organic direct between them there should be a bond you understand yes hey so My friends are like these carbon and oxygen There is a direct bond between the carbons There is a direct bond between oxygen But can carbon and hydrogen by themselves Is it directly connected or not? This is directly connected it is connected it is directly connected Hydrogen to Carbon Directly Connected So it is not no this is it what is it if not then what are you here will put No direct bond between carbon ends Hydrogen no direct bond between Carbon and hydrogen are therefore in organic declared tax Now you will remember it in this way you will do as I tell you ok So mineral acids or inoff acids are those which come from non-living sources such as Obtained from rocks and minerals hydrochloric acid sulfuric acid Nitric Acid End Carbonium nickel or mineral acids ok it is clear this is mineral acid why is it here there is carbon hydrogen Is there any direct bonding between them? no it means that carbon hydrogen is together I have a direct link, if not then bye Say bye to him and send him away, it's okay So let us first start on the basis of the source There are two categories of acids: organic [Appreciation] I hope I will meet Inoff and Mineral You must have understood both the categories. You will understand the classification, look carefully son Classification of acids on the basis of presence of oxygen Is there oxygen in the acid or not? If not, so what ifs what isn't for If there is no example, we will call it Hydra what will the acid be called hydra acid and if if there is oxygen then what will we call it oxy acid now suppose if there is no oxygen then we will call it hydra acid So this is the binary compound we have off Hydrogen with any other non metal like Fluorine Chlorine Bromine Accept Oxygen what do you mean by say There are acids that do not contain oxygen So the first category in that is that is called as hydra acid now hydra acid which is Binary Compound Binary means that its There will be two elements inside how many elements there will be two elements there will be two elements There will be a hydrogen in it will go one will be hydrogen the other will either fluorine would be either basically chlorine or Basically bromine but no oxygen will be like hydrochloric acid Hydro brom acid will become All of this will become hydrofluoric acid all done well let's talk about others for Example: Let's talk about the second one here we have ternary compounds means that which has three elements in it three elements are evolved that we are called as the ternary compounds three elements means that hydrogen is a would be a nonmetallic element and at the same time Oxygen is also There will be acids, I told you about two Category on the basis of presence of oxygen if there is no oxygen and oxygen if it is not there then it is a binary compound that is Hydrogen will be there and a nonmetallic element If oxygen is present then it will be a ternary compound That is, a compound of three elements is a hydrogen, oxygen, and a third nonmetallic element such as sulfuric acid like nitric acid what is carbonyl acid called hydra acid listen again is it oxygen or no if there is no oxygen then it is hydric acid If there is oxygen then oxy acid is hydra acid binary compound made of two elements one hydrogen and one nonmetallic element Oxyacid three elements one hydrogen one oxygen and one nonmetallic element I hope both things go well you are understanding from Raja beta is coming Raja beta is coming ICSE 2021 question will be Hydra Acids are the acids that contain acids quickly I will tell you quickly I will tell you quickly I will tell you quickly ok yes there should be no confusion about this there won't be hydrogen with any metal right? What does hydra acid mean? Hydra Acids are binary compounds that have two There will be elements, one will be hydrogen and Any non-metal can be used with it fluorine chlorine bromine can be accept oxygen ok good morning esan yashika little baby Jeevika Anya Kim Jisoo Dolly Lyrics Universe and Hanuman kind very good very Excellent so see hydro will be a non with it There would be metal other than oxygen, right? Hydrogen will be hydrogen will be binary compounds of hydrogen with any other nonmetal like fluorine chlorine bromine atas accept oxygen i.e. It will be a binary compound in which there are two Elements have evolved, one of them is hydrogen itself the other one can be any non metal Fluorine Chlorine Bromine Accept Oxygen I enjoyed it, I understood that you are having fun this time You are not coming friend brother sahab friend hey it's fun No one is coming, should I call Shiv ma'am? Hi hello Sunil Bhaiya, I have read it now wow hi kids i will teach you Assets wow Sunil Bhaiya wow what did you write yes you have Sunil bhaiya ah ha ha ha ha Sunil Bhaiya Shivangi mam come to the glass Shiv mam OP Shivam Oops, Shiv ma'am came and went after reading it. Brother, this is enough for me Thank you, it is not just a matter of brother Shivangi mam came and ran away after seeing brother hit me Sir, I have not said anything about this, here comes Sunil Bhaiya where is this he is beyond my control Brother, it doesn't matter ma'am, I will teach you. go no problem no problem we we will teach we will teach So now let's talk about another definition of acids I do it but again there are restrictions to the The syllabus should not be like this, Raja beta 11th Go study the Ionic Equilibrium in class There you can read the definition of acid and then read my article. abuse me that's why I wrote up to the syllabus Well I will teach you Ionic as well I will tell you now let's look carefully look carefully what Are Acids So Acids Are Acids Are Defined As The Compounds Which Contain One and More Hydrogen Atoms and When Disoldering ice and the h+ aqua ice It is a matter of great depth In class 11 you will say it as Aarhi Nius concept of Acid is not a different concept of acid I will teach you this in 11th class You will speak of unusual concept of Acid means here it is saying that Acids are hydrogen containing compounds For example, let's say an acid with which there is a non metal this is an Acids Are Defined Compounds Contain one and more hydrogen atoms has one or more hydrogen atoms and Any non-metallic element is for example x is like we mixed it in water and called it h2o Are Water and she is crazy about Sunil Bhaiya's class be careful Look at this acid mixed with water I, my king, play the question instrument This is saying that as soon as the acid jumps into the water As soon as he says water, Raj jumps in But here acid is flowing where there is water I am there because I am of the water The acidic character of Diwani acid is dissolved in water If there is any acid then I am coming hu bhaiya i will come inside the water and water What will I do when I come? Will I say, look brother, I I will give it from here, inside the water would come inside and give h+ and the h+ that it gives, this h+ goes to this Acid gets attached to water and gives h+ in Water gives h+ inside the water and this h+ if it sticks on it then h+ sticks on it Remember what happens when it sticks What is made of does h3o plus last or not Open the chapter and see Coordinate Bonding I taught you come son h2o + h+ will give h3o + and with in my King x my so this is my king acid and this is my If water is king then what does acid do when Disoldering As soon as it goes inside water, h+ will come out and h+ will come out which will collide with water and If it sticks to the water then it will turn into H3O and Raja beta this will be called hydronium ion wow wow wow wow wow wow it's fun it's fun it's fun If it goes then the acid will go into water and give h+ and come back If h+h p gets stuck then brother it will be called h3o p and this is called hydronium ion aha bar are you having fun brother sahab I am having fun brother Saab now did I teach this or not This was between oxygen and hydrogen brother this is callen band brother what is callen band will be coordinated Bond, open the last class and see, this is it the hydronium ion is the coal bond Bond Coordinate Bond So what is this hydronium ion? I remember Oxygen has two loans The pair of electrons is H+, it will say Brother give it to me I am poor There are no electrons here, both oxygen what will the two electrons share He will give it and will say, Bhaiya, whatever you give They are electrons, both yours and mine I also explained this in the last class coordinate bonding will occur and with x+ Now, it is clear here that Just like we basically dissolve acid in water If you dissolve it inside then that acid will dissolve in water Later it will give h+ which will attach to water to form h3o will make it and what happens because of this h3o p This is the reason why it has an acidic character Acidic character is because of This acidic character is because of the acid of this acid The character is because of this, it is acid The acidic character is due to this which What do we write for hydronium ion? We can also write and h ps Acidic character of aqueous is because of this particular or this particular ion same thing Is okay so this is the acidic character of the acid but The question comes in the child's mind that when h ps if he jumps in the water then brother it Why there is no independent existence why does it need water Why staying single can't make this a relationship What is the need to come in hey Sunil bhaiya why is this hps like us why is it Sunil bhaiya this is this hps Why is Sunil Bhaiya like us? Why is he like this? Why does it need to be patched up Naughty boy goes into relationship again and again He is just like you, he doesn't understand what is naughty boy naughty boy naughty boy He doesn't understand and goes into a relationship but the reason for its relationship is different He has no compulsion, you have no not compulsion it's your compulsion, it's attraction, it's fun remained Your senses are not under your control If you are unable to control your senses then Destruct I am understanding yes hey Brother Ashita is saying sir don't do it personally Hey son, where is it getting personal, I am telling the truth remained I am here and what is it, it's been so late now I was talking to a girl like my brother I said she made me her sister, very good Son, as soon as I see the chat, I become a sister you have taken it son, very good and now that Son, she is your sister permanently, to tie Rakhi prepare for it by tying ashes to it I understood, but I didn't want to come back Son, you should start talking to someone with a sister gonna If Sunil Bhaiya saw the cancellation then he would say sister you are my naughty boy get away from the camera jump straight home I'll go somewhere else, it's starting to hurt as soon as I I start looking at the camera and say you are mine you are my sister and the rest you are chatting, where do you stay ho how are you you are different you are naughty Son, it's a different note You should know how to take part in poll question It's very easy, just do what feels right to you Write that particular option in the comment he will automatically take the section okay let's go and I have any doubt, can CBSE people see it? yes yes you can definitely see CBSE Why can people see Salt at all don't see that part, just see the nature of salt Watch the last, absolutely last part The rest is just your syllabus and tell me let's go done done now look now let's look carefully that the h plus ion is independent of Why doesn't there exist? Why don't they? have an independent existence Why there is no independent existence let's understand this particular point h is independent of p a Assistance Suppose Acid Inside Water he went and broke down and gave h+ so why is it necessary that it gets attached to the water is the reason do you understand what is the reason now my Brother tell me one thing this is h and accept this what does h ps hai mean If I write this down, the number of protons So if I write one in this and one in this am the number of electrons and let's assume that number of neutrons is neutron neutron zero electron inside it one one proton one electron zero neutron is neutral only when An electron is a proton and a positive particle is a negative particle so It is neutral but there is an imbalance here It is saying plus, which means it is telling that there is one more proton than the total number off electron is now a single proton so That means how much electron here will be zero here one proton is one electron So this is neutral there's a proton here If there is zero electron then the charge is zero plus then what does it mean that h+ is only and just what is that is nothing but a that is nothing but a that is nothing but a bear Proton it is nothing but a proton hey do you understand it is not coming h+ and nothing else there is just one proton, that is there is only one positive charge and There is only positive charge which is Extremely Small Extremely Small in Size The size of the proton is very small. What does it mean that there is only one proton? That is just a proton which is very small in size and the positive charge is now smaller in size and Positive charge is small in size and positive what is the reason of charging there is a charge on top of it What is high charge density? What is high charge? Density what is high charge density is high Charge Density A small charge means a Very high charge in small space Density is the positively charged part is just a bare positive charge extremely If it is small size then whatever is its charge density What happened basically, high charge Density is the right thing Now this is because of the high charge density what is it is also unstable and highly Reactive as well it has high charge density, right any electrons to neutralize It is not here isn't that it's just a little positive charge isn't it the one who is wandering here and there Precisely because of this it is very unstable and It is also very reactive, now it is high If the charge density is unstable and highly If it is reactive then what will it do instantly attracted attracted two lone pair of oxygen Do you understand atom? Now basically what is this, this is a positive Charged h+ ions h+ ions are positively charged there is a very small positive charge so oxygen This electron is this lone pair which It is negatively charged and is attracted towards them You will be attracted towards them instantly A very small person wants to react There is only a small positive charge This is space, there is high charge density, right? because the size is very small only positive If there is charge then the charge density is very high what are you doing, I want to react quickly If he is still alive then what will he do with this loan payer he will attack quickly, if he attacks then what will this become here we have a hydrogen this Kovalenko valent bond and this shared pair of electrons for both of them between this is one pair of oxygen this is the second pair Both of them have shared this kovalenko valent bond so that is basically h3o p will be formed like this because acid is like it releases h+ in water only h+ is nothing but a bare positive charge i.e. It's simply a proton, you just need to understand that you will have to wonder what h+ is h+ is nothing but a Proton It is Nothing But Just a Proton You have to understand that the size is quite small There is only positive charge due to which high Charge density is low so the loan is paired off quickly oxygen is attracted to them wants to be attached so that he becomes stable that is not stable it wants to be stable so what will happen as soon as it comes here to attaches with h2o attaches with h2o to form h3o p ie h3o p attached with water means will create hydronium ice I hope you understand all these things it's okay if you can understand that much So brother, please come once and write to all your friends I will give you a gift once brother, I will write it down Classifications cleared by taking third I am going, please tell me carefully, before doing anything quickly Classification of Acids on the Basis of source organic inof second Classification of Acids on the Basis of presence of oxygen now third Classification of acids on the basis of The basicity is fine, I will tell you quickly a child was asking me bhaiya what is this This is coconut water my brother, now I have drunk it at night No food of If you need something for energy, eat it I take coconut water like this Whose is this row fruit its coconut water hey you guys eat your food okay is in the middle whichever child feels I please go in between and eat food once take them sitting with mom and dad don't worry eat your food Let us now look at the classification of acids based on We will talk on the basis of basicity We will talk about acids from the first source. Organic Aortic Second Presence on Basis Hydra and Oxy on the basis of Oxygen After that we learned an important concept that acids dissolve in water to form hydronium ice due to which their acidic now the character is of acids Classification on the basis of their basicity Let me tell you in simple language what is it a molecule of acid is a molecule of in acid water Water In how much h3o or h+ aqua will it create This is just your basic work finish if we say here what is the Basicity of an acid in simple terms means this is a molecule of acid when inside the water If he goes, how much h3o will he make of it Basicity is a molecule of acid If the king goes into the water, how much h+ Aquas or H3O will make this thing my king it's called basicity hey i am able to understand I am unable to make you understand that I am saying this I am saying that a molecule of acid is An acid molecule which when dissolved in water if it breaks down into how many h3o or h+ What makes Aquas is its basicity If I haven't come, I will come now, see son Basicity of an acid is defined as the number of hydronium Ios and h+ Aqueous h+ aqus that are produced by the ionization of one molecule of acid in the Aquas that is, when the ionization of that molecule hoga the meaning of io ization i.e. that there was a molecule of ice inside the molecule was not in form but when it comes in water and if it breaks it will make ice that is called edge Difference between ionization, dissociation and ionization I will also teach you electrolysis Ionisation means that the acid has a there's a molecule inside the molecule right now this it is not in ice format but as soon as If you go into water, it will come in ice format will go to h+ aquas and then anyone else who He will be an anair person and will come back in form This means that when we mix acid If put in water, how many molecule of it h+ aqua or how many h3o will it give This is the basicity now look here carefully Let's understand things a little better Let us understand from this that first comes the monobasic Acid comes second, dibasic acid comes third Here comes Tri Basic Acid, Let's Talk About The Monobasic Acids The Monobasic Acids What are what is a monobasic acid Sunil Bha is monobasic Acid Mono What is Mono? Mono Dye TRAI TRAI Dye Mono-mono means that it has one When the molecule goes into water it forms an H+ Aquas will make dye means its a The molecule will form two h+ aquas of try That means one molecule of it is made of 3 h+x It's as simple as that, once it's over, acid comes on Ionization Acid Witch On Acid Witch On ionization in water produce one Hydronium ion on the molecule of the acid That is, the acid which if we dissolve in water If dissolved, one molar i.e. one hydronium ion is a molecule will make such acids whose one molecule is cool a hydronium ion will form, what will you are monobasic acids such as for Example for example if I am here I write that hs aquas is ready to go into the water After that it was directly written aquas which means water in then it will make h+ will make cl1 my in aqus x An h+ aquas is released from a molecule a cl1 my aquas derived from a molecule one h+ is coming out so acids witch is on ionization in water produce one hydronium ion per molecule this is hydronium ion or h3o p or h+ x both means the same to a molecule an h+ x It is extracting this means this monobasic acid it is good sunil bhaiya inside ch3cooh Bhaiya four you have hydrogen so if you A little detail on the basis of its structure In If you read it, what will happen here my friend? it's monobasic right now you just have to do this remember if this breaks inside us is ch3cooh Aquas so what does it give us here Here we have this gives us 1 h+ x this gives us 1 h+ X one molecule means one molecule of this One h+ gives an aqua so it is monobasic It is acid and it depends on its structure also It depends, right, which there is structure inside it now There is no basis for your course explanation in that case i.e. here in this structure O bond is same in basis here polar bond means there is only one so this O bond is one What will water do if polar bond is formed? If you break this then an h+ aqueous will come right away You don't need to know much about this All you need to know is that acetic acid which is a monobasic acid, one of its the molecule will release an h+ aquas understand You have come, ok pay attention to the arrow here. This is basically complete here does not dissociate under water yet I will explain further about strong and weak acids. Inside, you must remember that I made the complete arrow here I made such an arrow, now this is what I told you next You will understand the difference between strong and weak acids An h+ x came out from one of its molecules An h+ enzyme was released from one of its molecules means it is a monobasic acid in the same way if Here we talk about acids which on ionization in water produce to Hydronium ion on molecule of acid That is, two hydronium ions in one molecule di basic acids are produced from okay now here you will get another For example, phosphorus looks like this Acid Phosphorus is acid h3 po3 now here you can see there are three hydrogens but actually its One molecule releases two hydrogen isolates because of which two will be inside the water Hydronium ice will be formed, ok ji try basic acids so these are basically those acids ionization of acids in water Produce Three Hydronium Ices on molecule of acid i.e. three hydronium is a molecule of acid If it releases then we basically call it is this called as the tri basic acid ok it is clear so classification On what basis did we do the most of the acids First of all we did it organic on the basis of source and inoff gni second on whose basis did we Kara on the basis of presence of oxygen so hydra acid and oxy acid if not If there is oxygen then hydra acid will react with oxygen If yes then it will be oxy acid On what basis did we make the third classification did sunil bhaiya classification of acid Based on basicity i.e. a molecule of acid which would be one molecule of acid how much h3o + aquas after going into water how many h3o + ice or h+ aquas making He is making it, he will define its basicity If one molecule of this is formed as an h+ aqua If it is monobasic then one of its molecules is if making two then die basic its one If the molecule is forming three, then its Meaning tri basic acid work is finished Sunil Bhaiya one more doubt is coming in my mind Can we define basis in this manner as well? can you do this yes you can also do this basis I can define it in a way right now I will tell you, first ask this question, The Basis of acetic acid just now i told you What is another name of acetic acid? In organic chemistry we study Thinok I have taught you acid now I will teach this online as well ch3cooh is its formula or you we can write c2 h4 o2 we can also write c2h 42 Basis Very good very good very nice you guys are very dear child you know you are very good Children should study honestly like this remained Do classification of bases based on Classification of bases based on acidity and not On Knowing it on the basis of acidity It's a simple thing, a Malik will try off base now look suppose if I say hoon one molecule of base one molecule of base one molecule of base one molecule of how many o minus ices will the base release minus Ayes Release will do in x sl molten form meaning Meaning look all your bases are just water those who dissolve in water do not dissolve in me what do we say, we also call it alkali Memory Remember here: Water Soluble Bases Let me add one important thing here only only some bases some bases are soluble in water some bases in water soluble is only some bases soluble in water And this is called alkali which is called s alkali so this pointer number one it means What is it? All the alkalis are bases. All alkalis are bases. All alkalis are bases. we have those bases but all bases are not Alkali understood this Can we call water soluble bases It is said that alkali means all alkali bases but not all bases are alkali Because all the bases will take some water Hey, do all bases dissolve in water? For example I write ao paani dissolves in k dissolves in water But if I talk about copper oxide then who is the base among these and in this who is alkali from tell me who is alkali and Who is the base If the hydroxide of the metal is then the base will be If it is metal hydroxide then base will be metal If it is an oxide then it will be a base then it will be a metal Hydroxides and Metal Oxides are Bases Everyone knows that it dissolves in water yes it dissolves it dissolves it dissolves yes its not dissolves this base this base this base this alkali Alkali this is not an alkali so all alkali are bases but all bases are not Alkali is not necessary in all bases of water If it dissolves then the base which does not dissolve in water It is not alkaline but the base which is present in water it dissolves it is called alkali okay g third Pointer Some Metal Oxides Some Metals oxides metals Hydroxides are basic in nature also Remember, some metals are oxides and some are metals Hydroxide and Ammonium Hydroxide Because it is the hydroxide of a nonmetal are basic in If you are trying to understand nature then it is the oxides of metals Metal hydroxides and ammonium Hydroxides are basic in nature I give you example as it is basic in nature like it's basic in nature like this it is basic in nature as if it is basic in It's nature, right? These are metal oxides. and metal hydroxides are then metal oxides Metal Hydroxide and Ammonium Hydroxides are basic in nature ie this is the base we have na2on [music] That for example all these bases are alkalis no it's ok it doesn't dissolve in water It is not alkali but is base so it is metal Hydroxide and ammonium oxide of metal Hydroxides are basic in nature I have written here it is like this, not everyone is something What are the oxides and hydroxides of metals They are double faced, I would have written this also I am here But I will also write this, some metal Oxides Some Metals Oxides and Hydroxides R Amphoteric What does amphoterican mean? amphoterican means amphoterinic means Acid Age Well Age base means it is like acid as well as base can work as both e.g. for example for example i for Example: Suppose I am a strong acid okay I'm strong acid and I I went to Shivangi ma'am and I told Shivangi I told maam that Shivangi maam I am strong I am acid Shivangi mam I am strong acid so what did shivangi mam say yes Sunil brothers you are a strong acid, I have said yes oh bhaiya I am base, okay so I He said that I am a strong acid so maam what did you say mam what is it it is base a reaction happened ok Now as soon as Upasana mam came to know about this Duggu ma'am came running to Duggu ma'am I was the acid, Sunil sir, since when did you become acid? right? So she said now I am Shivangi I will have fun with ma'am, Shivangi came to ma'am why Shivangi mam Shivangi mam said yes She said, it is me, Upasana ma'am, who is saying that She is the base, Upasana ma'am is saying that she is the base So what is Shivangi ma'am saying, look Shivangi Maam is saying are you base then I am acid I am understanding that now the base is in worship only When it was ready, that Shivangi came to Shivangi ma'am When she came to ma'am, Shivangi ma'am said come you If you are a base I am an acid now see when I When Shivangi ma'am came as acid then she became base Upas mam came as base then what about Shivangi mam When acid was prepared, Shivangi ma'am doubled it Shivangi mam played a game and became emphoteric If a heavy acid comes then the base becomes heavy If base comes then it becomes acid, end of the matter. Are you understanding Sunil Bhaiya? As soon as I went here in the form of acid and madam I will say that I am the base If I become a base in fasting then I am an acid Now madam is enjoying us so what are you madam If it becomes amphoteric then some metal Oxides and hydroxides and ammonium Hydroxide is basic but some metals Oxides and hydroxides amphoteric who is who From a a b p jd eights s bhi p jd ase bhi p jd what does it mean that Tin Aluminum Beryllium Lead and Zinc Tin Aluminum beryllium lead and zinc then tin aluminium beryllium lead and zinc as their metals what are oxides and hydroxides The Are Amphoteric The Amphoteric Acid or Base Now you can act like both of them After knowing the basics we will come here So now we find things relatable here. Now you will wonder what the acidity of a base means What is the meaning of acidity of a base here has it is defined as a number of Hydroxide or Hydroxy Is That Can B produced by the ionization of one molecule of one molecule of that base in Aquas and the Molten In state understanding i.e. if a particular base is If I put it in water or I melt it One molecule of it has as many O minus ions will produce this is the acidity of that base and the basic character of base is basic character because of yes again this is a concept from our syllabus Basic character basic character is because of this that the basic character is h mine is ki Because this is again limited to our syllabus It's okay, now inside this also our What types of bases do you have? First mono acidic base comes second Third, we have di-acidic bases. We have a tri acidic base quickly You will see mono acidic base means such a base whose one molecule will be more than a molten aqua in the state it releases a - ion right here but let me see, let me see, look at this Bases that dissociate in the molten or Fuse state and in the aqua solution to Produce 1 oh1 song nh4oh will also give a calcium hydroxide This one will give two, this one will give two, this one will also give two, Basically each molecule has three of these denge monobasic di basic tri basic talk End ok let's do this answer quickly Quick solve it quickly I will solve it quickly my dear dear king raja son The Acidity of Aluminum Hydroxide I we will finish it as quickly as possible finish early will reduce the acidity of aluminum Hydroxide is finished, what is the answer Its answer will come yes very good very good Ayushi Wani Hanuman Kind Mohammad U Monir Dancing Dawa Nishant Albert Einstein Anushka very good very nice so our pass correct answer what will be correct Answer: We will have three aluminium hydroxide then how many molecule of it o minus ises will give 3o minus ises will give so that is basically the acidity of aluminium Hydro oxide let's talk about the next thing now that is chemical properties of acids and bases means chemical What are the qualities we will discuss here? We will discuss chemical properties quickly will finish it, starting soon So See the first one is reaction of metal with Dilute Acids That is, if the reaction of the metal is diluted what will happen if it is due to acid now like for For example, if I ask this question Let me see what kind of reaction this is What kind of reaction will there be? good very good very good all the children absolutely giving the correct answer are quickly, quickly, say very good very good very good ok si C C C very good very good very good very good c is the correct answer now pay attention You see, the question is saying, look at the concept Concept of metals v dilute acids We have OK now you look carefully here What the pass concept says is that whenever Whenever the reaction of our metal With what will our metal be diluted, son? Whenever our metal will react with acid If it is with dilute acid then be careful listen if our reactivity of metal will listen carefully If reactivity of metal is greater than the Hydrogen Off Acid if reactivity of metal is greater then the hydrogen of Reaction of acid metal if dilute acid and if the reactivity of the metal more than hydrogen of acid the reactivity of the metal that is greater than the hydrogen of acid then this is what will it do by displacing The reactivity of the metal is greater than the hydrogen of acid then it displaces it what will it make of zinc chloride will give and will come out here with our Near Hydrogen The reactivity of zinc gas is proportional to chlorine What is the reactivity of zinc here? The concept is more than hydrogen If the reaction of our metal with dilute acid Getting Acid Dilution with Salt should not be concentrated and If hydrogen is not formed then the acid The metal reaction will have to be diluted if Getting Along with Dilute Acid and if the reactivity of the metal in acid If there is more hydrogen present, then it will form Here the salt of the metal is zinc Chloride and hydrogen will be released along with it gas good hydrogen gas here how Hydrogen gas will be released, it is evolved in the Form of bubbles i.e. bubbles will come out along with the physinorm ming that is very fast will come out A sound will come out and foam will form, forming bubbles If gas comes out then do this technical procedure what is called effervescence Effervescence in hydrochloric acid e.g. as soon as you add zinc If you put small pieces in Because zinc has reactivity in acids This is more than the present hydrogen What will zinc chloride make by displacing and also hydrogen gas now hydrogen The gas that comes out forms a lot of bubbles A glimpse comes out and a sound is heard Bubbles are forming, the sound of fission is coming Babul format is being formed Gas is coming out in this technical procedure what is called effervescence Effervescence so we have it 100% displacement reaction this is an Example of a displacement reaction and which displacement is that too where one a metal is displacing a nonmetal that displacement Which is metal nonmetal displacement? Reaction is a metal and a nonmetal is hydrogen that one is displaying This is a displacement reaction, ok bhaiya who is it Who else can displace hydrogen If you are not able to do it then you can show reactivity for it Remember the series, it is a simple thing for you This trick should be in your mind, girl kudi kudi kudi kudi kudi kudi kudi kudi kudi naal kudi naal car manga alto kudi nal ask for a car Alto which we will take again and again Whomever we take with us, we take with us again Whatever we take with us, we should not take it with us again Mathura seven places to visit Symbol Mathura seven places to visit Pratik Mathura Seven Tour symbol okay so look here here See Potassium Potassium Sodium Calcium Magnesium Aluminum Zinc Iron Lead Hydrogen Hydrogen Copper Mercury Silver Gold and others what will come to us in the end will come Platinum Kunal car which was driven by Priyanka Chopra Kunal ask for an Alto car which we will bring back Come let's go out with me Pratik Kunal ask for a car Alt with whom we again went for a walk with me symbol potassium sodium calcium Magnesium Aluminum Zinc Iron Lead Hydrogen Copper Mercury Silver Gold Platinum I understood the point, yes I understood it It went great so here we have Hydrogen why is it because hydrogen can behave like this metals it can behave as metals that's why it is kept here it can behave as metals that is it can't loose n Electrons make them behave like metals and has the power to loose an electron Hydrogen can behave as metals Hydrogen can behave like metals that is, it can loose an electron That is why in the reactivity series of metals I have placed it, the more metal there is on top Will be more reactive from top to bottom If you come, will the reactivity decrease? Reactivity will decrease to the top potassium sodium coming to the bottom Calcium Magnesium Aluminum Zinc Iron Lead Hydrogen Copper Mercury Silver Gold and Platinum reactivity will come down from top It will decrease, it is a simple thing Correct well hydrogen is basically here It is kept because it can behave edge metals can loose electrons then The one above the hydrogen will which hydrogen can be replaced by acid They will not be able to replace those which are below Correct Let's quickly move on to the second reaction We will see our second reaction very soon Nearby is the reaction of metal carbonate and metal bicarbonate with dilute acids now this What have we done in reaction to the question Read the question, one we put a row says Egg Raw The shells of an egg Look at the shells, what are they made of R Made from calcium carbonate so you picked up a raw egg and You put it in a beaker which What is basically inside, inside which the king is son who is vinegar vinegar is lying there inside which So there is a beaker with vinegar inside it. We put it inside and the egg shell is it's basically made of calcium There is a beaker of carbonate in the beaker put the vinegar into the vinegar beaker the egg shells were basically made of from calcium carbonate so here bubbles You will get basically gas access Identification let's do it okay so here is gas x Which will be the identification? We have added vinegar to it, that is in vinegar ch3cooh it is near it katai nick part and it's near anair sorry sorry sorry sorry it's near anair and this is katay nik part ch3coo 1 mine this is son which ion hey raja which ion is it Sunil Bhaiya if there is acetate ion then listen Son listen carefully this is cut with this pineapple will will The king's son will go This will go with this and this will cut with this exchange of nines is happening couple exchange The dance is happening Kataya Anaan Katan Anaan To these cuts with pineapple these cuts with pineapple Couples are dancing together What did I basically do when I went with Anna? Our This turned out to be calcium acetate [music] What happened? Calcium acetate became This cutlet went with naan so what did it become h2 became co3 it will break into h2o and co2 Understand inside, my love Monkeys are either metal carbonate or metal hydrogen Carbonates such as, for example, calcium carbonate is converted into acetic acid i.e. vinegar I added vinegar in diluted form of Acetic acid is sold in the market Vinegar or syrup from which noodles are made If everyone would know then this knife is of this eye This Katan went with Sanan and then it was made calcium acetate i.e. metal of carbonate or metal hydrogen carbonate If the reaction is with acid then it will be formed here salts such as calcium produced here acetate this cation goes with this nayan then calcium acetate is a mixture of hydrogen and If carbonates come then h2 co3 will be formed and always It will break, it will always break, in which h2o and in co2 so remember the product is metal bicarbonate or metal hydrogen carbonate plus acid will give salt plus h2o I will remember CO2 yes I will remember it What will happen brother, then carbon dioxide gas e evolved in the form of Bubbles along with fizz and firming this is none as the effervescence process okay so this Which gas will be released in the case co2 will be released wow my king you played the instrument come on Son, let's understand the next reaction Reaction of metal sulphide and bisulphide With acids sulphide means this ion this is basically sulfide this is basically by sulfite this is by sulfite ion this is a Poly atomic ion is bi sulfite or it is called hydrogen sulfites and that's basically what we have we have this of sulfides ion okay so this is what we have of sulfide ion and this is what we have is hydrogen sulfide or basically bi sulfide ion now attention Look at a little calcium sulfide or sodium hydrogen sulfide we have this its cutting part is this its basically There are many parts, similarly we have this cut nick is the part and this is what we have is it sulphate of anayat or bi of metal It is sulphite, its reaction is happening with acid so this is the reaction of acid and this is the reaction of acid it is naayan, it is the antacid of acid and this is the antacid of acid Nayan If yes then you can exchange the Katay Nayans my friend this Katay will go with this Nayan So calcium chloride will be formed by cutting this If it goes with Nayan then it will become Sodium chloride now look ahead carefully see son Listen carefully, this is calcium and chlorine Sodium salt of calcium chloride prepared and chlorine combined to form sodium salt of chloride son see this h2so 3 and h2so come to me listen to me dear son h2so 3 will break here h2o in and so2 did you understand that h2so will break down into h2o and so2 Sunil bhaiya which are these two reactions This is the type of reaction of son Katyay Nayans If exchange is taking place then double displacement which reaction is this son it is double Displacement Good Double Displacement Reactions also have three types Majorly one is that in which insoluble The second one that forms a solid is the one inside which Neutralization Acid Plus Base Will Give salt plus water and the third one is in which that gas is produced so here in double displacement Which example is gas forming reaction example of This is the third type of double displacement that gas is being produced yes it is double Gas forming in displacement reactions is an example of similarly if we look at its If we talk about it then it is double displacement Example This is an example of double displacement hay katay nayans exchanged to become h2so 3 it will break down into h2o and so2 gas formation If it is happening then it is under double displacement There is an example of gas forming reaction in so if the question comes in the exam Let us see that if metal bisulphide or Metal sulphides react with acids So which gas will be made, will you eat tikka of so2 you will go above and beyond if you buy metal carbonate or basically metal carbonate If the reaction is with acid then CO2 will turn into metal Reaction of bisulfide or metal sulphide if it is due to acid then it will become SO2 and my king Play the concept if it is made of metal If sulphide reacts with acid then what will happen listen again metal carbonate or metal Reaction of hydrogen carbonate with acid If it happens then CO2 will be formed and metal sulphate will be formed Reaction of bisulfite of metal if acid if it is from metal then SO2 will be formed and if it is from metal If sulphite reacts with acid then it will give H2S Did you understand it or not? I felt it was a success. So watch carefully, my king will play it concept's baaja see this my king see this My Queen listen to its story son oh my king My queen, listen to its story son Sunil Bhaiya that you have to create a ruckus in the verbal exam Machani Machani look carefully at the metal son I took zinc sulphide sulphide of iron sulfite acid taken sulfuric We took hydrochloric acid Sulfuric Raja understood this acid, this cut is with this eye If this happens then zinc chloride is formed, this cutting of it Hydrogen sulphide was formed when it came with Nayan Seeing this the king went with this Katane Anaan Made iron sulphate this went with the cuttings anan So hydrogen sulfite became the issue and this also ended What is double Difference between displacement and double displacement Whose type is this oh my king tell me quickly king son king son king son king son king son king son king king king king king king king Which gas in double displacement Forming reaction gas is being produced hey it was fun O! oi hydrogen sulfite The gas smells like rotten eggs Like how is the smell rotten egg smells like rotten Foul smell like rotten egg the smell of so2 it's the smell of burnt matchsticks Is Smells Similar Two one we burn a match stick when you burn a match stick When you light a matchstick, the smell you get is It smells the same because it is there if only so2 is being produced then same It stinks and CO2 has no odor at all It is a colorless, odorless gas, it has no No color and no smell I understood it, it is absolutely correct no problem no problem come on son ask this question quickly it gonna solve this question official Compton focus question is solved quickly Let's see how many children solve this Question we will solve it quickly 9 b 45 is eliminated We still have over 600 kids sitting here what's the matter very good son quickly from quickly from quickly from quickly from quickly Look son, let me tell you something look carefully look at what I say carefully Nonmetals have oxides, what about them I will give you some knowledge about non-metals look son, those oxides are there All of them will be very acidic, son that neutral it would be like let me give you an example like Let's assume it is carbon monoxide or not n2o Is no that means it is nitrous oxide isn't it like That h2o these are all oxides of non metals Neutral it is acidic now see son it is co2 no2 it is so2 it is so3 son it is just like water It will react with you, it will make a good acid It will react with water to give it will form carbonyls it will become sulfuric it will give it, it will make two acids Two acids are formed: nitrous and nitric acid gives This is what happens next when we study compounds If you study then something will come there too Nonmetal oxides are acidic because they know how to make acids and some Neutral is one who does nothing No acid build up Now look, son, listen to what I say carefully to acidic what is an oxide acidic oxide is the nonmetal Oxides Basic What are oxides Basic oxides Metals contains oxides of it's ok amphoteric oxide shivu mam shivu ma'am shivu ma'am shivu ma'am to shivo ma'am kya such oxides of metals or such hydroxides that behave like both like acids and bases so if right now these talking about amphoteric oxide Metal oxides that can react with both Acids and Bases i.e. Shivu Mam Acid And the base is reacting with both because just like with acids and bases is interacting with the base and the acid Neutral oxide is behaving like this Neutral Oxides Basically we have What are basically oxides of nonmetals? So it will react with either acid or base See neutral oxides are non-metals If the acidic oxides are also non-metals then Acidic Oxide Non Metal Oxide Neutral Oxides are also again oxides of non metals which don't behave with anyone You basically have aluminum oxide what was amphoteric oxide finished If it's ok then we will get the answer for A. The answer for B will come to us, the answer for C will come to us. What will we get for One D's answer? what will come to you What will be the answer for 3 and e? tell me quickly my friend yes 251 34 25 134 yes piyush pish my brother you are absolutely right 25 134 Acid Oxides of non metals will be neutral Oxides Oxides of non metals which are acids Basic will not react with both Oxides Metal Oxides Amphoteric Oxides Metal oxides which are acids and bases Neutral oxide will react with both I told you look at this, aluminum oxide amphotec oxide is done it is sorted Very Good, you understood it till now, write it down Brother, please come once to Chemical Properties Our part is done, please tell me quickly once come Bhaiya, in just 47 minutes this much happened. I will try to finish it within an hour hurry to do do it Let's start with an introduction to the pH and PA scale A quick lesson on pH and the pH scale Know here, now see what is pH it happens let's see quickly So brother who is the sensation that we have the chef is basically a Danish was a chemist who in 1909 meditated See what happened in the year 1909 Suggested a way to express the hydrogen ion concentration of a solution in terms Off PA now what have they done here Suggested a way to express the hydrogen ion concentration of a in terms of peach now What is this method actually This is a form of quantification did you understand it Hear from Quantitation what it tells us what is the actual strength of the acid and base What is Qualitative Analysis? Now you can do Qualitative Analysis. Now you can use indicators are that is a qualitative Analysis Acid is the value of litmus solution If acid comes then it is red and if base comes then it is blue Suppose you have taken methyl orange If acid comes then it is pinkish red and if base comes then Yellow but which acid is so strong Which acid is weak and which is strong Who is the base, how weak is the base, it is not If you want to know this, I will tell you that in front how strong is the acid strong base is weak acid weak base so for this we have I will have to do it my friend here Quantitation analysis and that quantitation It is said that what tells us strength What is Acid and Base? Quantitation of hydrogen ion concentration Let's see how many hydrogen ions there are The higher the concentration the more acidic it will be The lower the number, the less acidic it is If yes then what does PH stand for here See also Does Peaches So Basically Have pH Stats for Power of Hydrogen Power Hydrogen This German word here is pH. It means potency D Hydrogen which means power in English Off hydrogen so german word for power that is potence y actual in tha potence d Hydrogen means in English Power of H stands for Hydrogen chemical symbol to power of hydrogen pH means the power of hydrogen again Listen, PH means Power of Hydro The German word was potens de hydrogen where But H is an elemental symbol. of hydrogen and p stands for potency in Meaning of the word potens in german english If there is power then there is power of hydrogen now Here Sorsan Maharaj says that if You can look inside a solution The higher the hydrogen ion concentration The more acidic it is, the lower it is, Less Acidic If yes, then he explained it to him in that way Quantitation Now look at this temperature It depends if we are at 25 degrees Talking about Celsius, it is 25 degrees Celsius. So solutions may have a pH Range from 0 to 14 0 to 14 this The scale runs when our temperature is it is 25 degrees Celsius Now see three types on the basis of this There are different solutions of acidic basic and we get neutral if If it is PA then it means that as much as The more concentration we have, the more we have h ps xga is equal to o minus x will be acidic solution means we have this is as much concentration for Example Concentration of a plus aqua concentration of hps Aquas is greater than the - What is drunk in aqueous acidic solutions if the pH drops below seven what will happen it will become less than seven i.e. concentration of h+ will be greater than x - aquas So the pH becomes less than seven if this is what we have pH concentration if we talk so if we talk about the concentration of h+ aquas so concentration of h+ aquas is lesser than the - Aquas are you getting the point or not p is equal to 7 so this is This means that the concentration of h+ is equal to that of x is the same as the concentration of X if h+ is more in aqua ion - aqua ion So the pH will basically be less than seven 6 5 4 3 2 a 0 if the concentration h+ of x - If x is less than p then p will be greater than 8 9 10 11 12 13 14 This is how this Ionic will go now You will come to equivalence in 11th class, then you will understand it well now you have to remember okay so when We have concentrations h+x and -x will become equal to acidic because of this character because of this the basic character if Their concentration became equal, that is number of eyes a which number of eyes a In particular volume, if both are equal then it is a neutral solution if their If the concentration is more than this then it is acidic The solution has a concentration less than so the basic solution is the basic solution is then pH will be more than 8 9 10 11 12 13 14 is acidic so the more than seven It will be less 6 5 4 times two and one will be more acidic and if it is seven then it is neutral, okay understand a solution Finding a Solution Haze Fifth note of musical scale 6 Vile inside Haze Peev Which Is More Which is more acidic? will a whose PA is 6 and b whose PA is 1 then What did I tell you? Your pH is as good as it gets will go down to seven 6 5 4 3 2 one same If that thing becomes more acidic then its The pH will become more acidic it will be fine Is Let's do the same thing diagrammatically here. We have told the same thing here You have made this thing diagrammatically You can see the same thing in the form here of diagram it is told that on seven It is neutral, if you go above seven then it will be basic If you go below seven, give me something acidic it is kept next we will see now here it comes that Brother how will you measure the pH scale like Suppose there is some visible indication need our pass like for example we need to find out is something an acid or a base if we know Want to find out whether something is an acid or a base? So for that only indicator is sufficient But if we want to find out how much of which thing It is strong acidic, it is weak acidic He has a strong basic and he has a weekly basic for this we have to use universal Who needs to use the indicator What is Universal of Universal Indicator Indicator Let's understand this particular understand this thing so here is the pH of a solution The pH of a solution can be measured using a universal Indicator ch is a mixture of thymol blue Finley Ates Now we have such an indicator here paid which is different h+ aqua ion concentration If it will give different colors then it is actually used to measure pH so the pH of a solution can be measured By using a universal indicator which is The mixture of different indicators like Thymol Blue Final Different Indicators Universal indicator is made from a mixture of and it has so much power that it gives us Can tell the strength of acid and base i.e. can do quantitation analysis do you understand yes it shows different colours at different h+ at different h+ aqua sign concentration it shows different colours it shows different colors at different h+ aqua sign concentration in the solution i.e. different h+ Different colors in aqua sign concentrations By showing us the strength of acids and bases Universal tells me to listen to you One such indicator is different indicators It is a mixture which exists at different pH conditions By giving different colours we can tell the strength of acid and the base tells yes you are understanding it Sunil bhaiya yes you are speaking to me Sunil bhaiya then this There is such a mixture of different indicators which vary over different pH ranges By giving colour we get the colour of a particular acid or base Provides information about pH does like for example for example If I take this particular example, I am taking this particular colour band Suppose I miss you do you have it The seven colour band V I B G Y R violet e blue green yellow range red then this You have to put blue here You have to put green here You have to put yellow here Orange and here you have to put it Red Blue Green Yellow Orange Red will come to us right here Greeny Greeny blue okay greenie blue here it comes Blue only blue or make it like this Dark Blue Give Dark Blue Blue Green Blue Green Yellow Orange Red It is ok na ji, now as for example Extremely something basic like for Example: Sodium hydroxide solution whose pH is approximately 14 so this is our The Universal Indicator is Extremely Pass Dark Blue Color Someone will give it, let's say it's mildly basic Like for example milk of magnesia If this were there then we would have a strong base but this is because there is very little water inside It is soluble hence it is a weak alkali is a strong base but a weak alkali age Let me tell you this right now Its pH is approximately 10. Pure water or If it is blood then its pH is almost neutral Lemon juice will give a green color depending on the pH Extremely acidic so reddish orange color The gastric juice will be almost Extremely red color if pH is 1.2 If it comes then it is different at different pH ranges The colour itself tells us that their What will be the strength and who will be strong It is acidic Weakly acidic Moderately acidic is it strong basic is it moderately basic or It is a strong basic, it will tell you everything, right? That Weekly Basics Moderately Basics Strong Basic Weakly Acidic Moderately Acidic strong acidic so all these things give us tell Will give it, brother, any paper also comes for this yes it is definitely available pH paper is available Look at this pH paper sold in the market we have this what do we do with it What do you basically do with a normal paper? will do it by taking a dip in the universal indicator If you dry it then it will behave as a pH Paper is generally impregnated paper strip. In the universal indicator is used for Measuring the pH of the Solution This Paper Strip is known as pH paper to normal You took the paper strip, friends? And You have dipped your Universal Indicator I have kept it aside to dry so that will behave As a pH paper, you should understand this my friends so that is called as the PH I hope you understand this much about the paper I must be coming, done, let's ask this question Solve Will do the official Compton focus question So it is a simple thing that I have told you till now Did you just tell me what pH means? Till then we were doing qualitative analysis Finding out whether something is an acid or a base But with the help of pH, we can find out Which acid is stronger and which is weak acid It is moderately acidic It is strongly basic We found out that all these things are weak basics we can with the help of pH and in that our Universal helps Indicator Greater and Smaller symbol is wrong Where is wrong my brother? hey my brother you are absolutely right The concentration of h+ - x will be equal to p what will be the concentration of h+ x greater will be o mine x because of this it is acidic character because of this the basic character If it is more, then Pi will be less than Sa that is 6 5 4 5 1 0 if h+ aqua ion The concentration of - will be less than that of aqua ion That means the basic rector is increasing by 8 9 10 11 12 13 14 If you go then this The concentration will be high, it is absolutely correct no problem ok let's go answer this quickly from the pH of the soil is tested and for the Better Growth of the Crops Slightly Alkaline soil is required i.e. we The pH of the soil should be slightly alkaline need very good choice in the fertilizer will increase the alkene hydronium Hydronium which is present makes it acidic Character Acidic character will increase will increase from hydroxy ion to basic Character finished What will be the basic thing from Kam O Mine Aquas Ion Character will increase the talk It's finished brother, please come once brother, please write it down quickly From last two topics only salts are left We will finish the work quickly about Quickly Saltus Its Types and the Nature Of salt please tell me once quickly From [Appreciation] Quickly Salt Its Types and the Nature of Saltus will tell you quickly fine than Now let's look at the nature of salts a little bit Let's quickly find out about salts I know about his nature Let's find out a little bit, okay? first of all what salts do we have r sults sults speak in hindi salts what do you say in hindi language Salts to salts are basically the ionic You know this much about compounding, hey What is an ionic compound that contains There will be one Kataya, one Anair, Sunil Bha Ionic knows the little things Compounds are those that consist of a compound As well as an anair hey I know this so Ionic compounds are salts that contains a positively charged ion, that is Inside it, there is a positively charged ion i.e. Katay which is usually a metal ion Accept Ammonium This Nonmetallic Cut is the ammonium ion addition to the ammonium ion E Basically Nonmetallic So first of all you should understand about salt We have ionic compounds called salts Inside which there is a cut which is usually a The metal ion is accept nh41 p i.e. except for our ammonium ion all the cuts we have these are the metal Ies so this is a positively charged ion i.e. Kataya is usually a metal ion acceptor ammonium okay and and and negatively Charged ion means an anion is a metal ion sorry non metal ions so we have salts Ionic compounds are those in which a Katay and one anair will pass Katay usually metal ion is non The metal ion is now a cation of We are also telling you the exceptions which ammonium ion which is non metallic still it is a if cutting is ok then there will be cutting and other things in it That means these will be positive and negative ions So we know Sunil Bhaiya would have cut and Raja's son will be an anair, what's the matter Sunil Very nice brother very funny So for example salt is sodium chloride magnesium chloride potassium nitrate sodium carbonate ammonium Look, chloride is cut here This will go to us, it will be cut into pieces, what we have will become what we have be an awry for example sodium chloride then the cutoff is na1 p and the cutoff is na1 p and the anair is cl1 - mg2 in magnesium chloride vice of cl1 - k1 p in potassium nitrate no3 1 - na2 co3 ment vice of na1 p and co3 inside 2 - h4 we will have here at nh4 1 ps and here the save mine will be there I hope you understand it It's ok son Sunil Bhaya will go ahead R Saltus Electrically neutral what do you think guys are salt Electrically Neutral tov hair ve There is no overcharge on Go Plus Would hey brother properties of bases are already Being As much as covered here in your syllabus I have mentioned all those things here. But we are covering your doubts It is absolutely genuine that Sunil Bhaiya is made of metal reaction for example that if We have the reaction of amphoteric metal if the base I have to get it done from him in Analytical Chemistry if you remember then your mind This is a curious question and it is a good one that sunil bhaya chemical properties of bases Physical properties are covered then chemical You have not yet covered anything in the properties If you do, I'll tell you what you You are saying example that bhaiya metal plus Base is amphoteric metal plus alkali. The reaction comes under analytical chemistry and there should be cover nice acid plus base reaction now It will be covered further here, right now I will cover you, don't worry, he will do it next If it is in chapters then I will go chapter wise I am doing R Salts as per the syllabus Electrically neutral then correct answer we have yes a 63 kids are fine Nishant Rajendra Albert Ain Daily Blog Amandeep Parveen Sat Sayam Seemas Ashwat Aham Very Good, now look at this thing carefully, quickly From We will look at the salts of electrically neutral What does electrically neutral mean This means there is no overall charge on them hoga there is no overall Charge there is no overall charge what does it mean this is that the charge is balanced Do you understand the point, what is the charge what am i saying balanced Ionic compounds are salts and sulphates is electrically Neutral There is no overall charge on these The more positive it is, the more It is a simple thing to be negative, give your mind I said sodium chloride I have a salt so my brother is on this positive charge and negative charge are equal Is there no imbalance, there is no charge It is as negative as it is positive So the balance is done electrically, right? You have become neutral, right? As positive as it is If it is that negative then it is balanced right? hey my brother is as positive as he is It's negative, the matter is balanced, the matter is over yes went to see this it See, the more positive the matter is, the more negative it is It's good that this example is over Explain this to me once you understand this example see this Son what is magnesium plus Charge how much is there on one chlorine The charge of minus is two, chlorine is one There's two on magnesium plus one on chlorine This is a minus, we have a total of two chlorine, so my king play this instrument a bit, this is basically t will become plus and this is basically a minus will go u plus u The more the minus, the more the positive, the more the negative as positive as negative as positive so negative thing The finish is ok Let's move forward now Let's move ahead, now we will understand here classification of acids Based on the strength I have seen so far Which classification of acids do you know? Explain, let me tell you the first thing I explained to you the classification of acids On what basis is it organic based on the source Acid inof Acid inof is also called Mineral Acid These are called organic acids which are present in plants Inof guani acid is obtained from and animals those that are obtained from rocks and minerals That is, those which are obtained from the living source and This money received from non-living sources is done Then we had a conversation here friends We discussed basically what those acids are about those who have oxygen inside them So brother, is there no oxygen in hydra? If there is no hydra then there is oxygen then oxy acid what did we discuss after that Afterwards we discussed about their basicity Basis Pe Monobasic Dye Basic Tri Basic That is, how many h+ x will one molecule give That happened inside the water on the basis of strength If we talk about it then we have two here types of acids and bases will be an acid will be a strong acid or Strong base weak acid or weak base is ok Yes, now this is a strong acid and a strong base Can you make a list once before understanding it? If you remember, I will remember you in the list I will get you the strong acids You should have a list in your mind that you we should have it in our minds like strong acids are let's suppose these are the Strong Acids: The first one is sulphuric acid h2so f is a strong acid hno3 ie that nitric acid is a strong acid Hydrochloric acid is a strong acid Hydro brom acid is a strong acid Hydro iodic acid is a strong acid But chloric acid is a strong acid and chloric acid is a strong acid hclo3 hclo4 h hb3 h2so how do we get all of these We have all of these acids Strong Acids sulfuric acid nitric acid hydrochloric acid hydro brom acid chloric acid on hydro iodic acid and Chloric Acid These Are Strong Acids Correct have accepted these seven acids i.e. these of the seven acids Apart from this all acids are weak We have weak acids including all What are organic acids saying If you leave these seven acids If you have memorized the seven acids, it means that you have memorized them. done basically sulfuric nitric hydrochloric hydrobromide If you do this then apart from this all the acids will Organic Acids Including All Organic acids or whatever acids remain All the acids other than these seven are weak You have all those weak acids are including all organic acids all the acids are weak in you like you I had written a statement generally about all Mineral Acids Are Strong Acids But Not All, look, these are mineral acids But one of these mineral acids is present in your commonly You must remember that H2 CO3 is not here This means it is a weak acid So you should remember the small things that I said that generally all minerals and Energic acids are strong acids not all because h2 co3 look at this It is not coming in the particular list Meaning it is not a strong acid but it is weak If it is acid then it becomes h2 co3 or it is also weak All acids are organic acids, citric acid acetic acid malic acid formic acid these Everything is weak acid now weak acid or strong What is the actual meaning of acid? Understand that this means that this completely Aquas will dissociate in ice In the solution, if you have calculated its solution as 100 put the molecule in water and no strong It is an acid and it is a strong base and you have 100 When I put the molecule in water, my brother Its 100's of 100 molecules for example It has gone into the water, now its worth Rs. 100 There are 100 molecules, look at the arrow Complete Arrow 100's 100 Molecules Broken will go and h+ x and o minus x comes It will finish the job, it is a strong acid Only 100 of its molecules are present in complete ice. if I break down then what will happen here there is only what is isis only here 100 molecules of ice 100 here in ice if you break down then that only means Is if we have here for example CH3COOH is a weak acid it has 100 molecules so it has 100 the molecule is completely in the ice The bars will not break here, they will partially break dissociate into eyes to give ch3coo minus and h+ aquas here its 100's 100's molecules your eyes will break, that means this one It is a strong acid but weak acid means or weak base means that partially Dissociates ice in the aqua The solution is that completely dissociate in two Eyes in the aqua solutions are basically strong acids and strong bases but which Partially dissociates in ice that partially dissociates into eyes in the Aqua solution means completely ice I will not break partially in your ice It will break into let's say 100 molecules of it If you go into water, all 100 molecules will go into your body broke into ices but if its 100 If we go to molecules then there are only 50 ices here By recombining the remaining 50 broken pieces back I understand that molecules are being made what is strong acid strong base weak acid Weak base means suppose any You have dissolved 100 molecules of strong acid in water If you mix it in then 100 rupees will break into ice will be converted but if weak acid we have like for example acetic Acid is a weak acid, I told you a little I told you this a while back when I was here Sorry, I was explaining about acidity Here I will tell you about Basicity of Acid When I was explaining this thing to you I was explaining to you here the basicity of I was explaining this about acid I told you the thing here as well that I told you this thing too what does the arrow mean so here if its If there is one molecule then the whole thing is in ice Two molecules will break down into three the molecules broke down completely but Here, let's say it has three molecules. Then some will break into ice and then some will come back we will make it with great difficulty, what does it mean partial dissociation occurs If you are understanding then there are two things here Does it exist? Two things exist because acids dissociate into complete ices did not do If so, two things exist here Both ices and molecules exist what do friends do and Both molecules exist and this also there are also ises and molecules both exist ok son yes Partial breakdown happens, that's absolutely correct So what does strong acid and strong base mean? is completely broken in ice and weak Acid Weak base means that partially ice I dissociate this will partially dissociate into ices and molecules here But I hope both will happen You will get some clarity in a good way There is no problem here at all right now after this we move Classification of bases based on the Strength: Such bases will be strong bases Weak base is a simple thing, strong bases They are those who dissociate in complete eyes the weak bases are those which Let's partially dissociate into ice now One small thing to remember about all this Metal Hydroxides of Group I and II Group Two of the Modern Periodic Table R Strong Bases Accept the Hydroxides of beryllium now like for example if we have group one we go to Lithium Sodium Potassium Rubedium Caesium and francisco we francisco we are radioactive If you remove it, we get hydroxide of lithium sodium potassium rubidium caesium all of these Hydroxide which is complete ice will dissociate, it has strong bases Remove beryllium from type group two So magnesium calcium straw is made shium barium these remaining four also have which are hydroxides of metals if water If I go then I will be in strong complete eyes we will dissociate, that means this also If there are strong bases then some four will be common I have written here four commonly used I have written those which are commonly used here. Sodium hydroxide potassium given hydroxide calcium hydroxide and Magnesium Hydroxide Strong Bases Apart from that, all the remaining ones will be week Bases are for example ammonium Hydroxide Copper Hydroxide Diaz R Weak Bases ok, let's say for both of them for example na1 p x and - X Now see a doubt in the child's mind It comes on what basis you are strong and weak You are saying hey my brother strong and weak I am telling you on this basis, listen to me so you understand my point If you go and listen to me, you will understand what I say will go once and listen to me properly From Listen, listen to me once and accept it 100% There were molecules, let's say there were 100 molecules of it you dissolved it in water for 100 rupees giving 100 molecules o mine x na1 molecule breaks down completely in water why are you giving aquas means 100 h my x Gave It broke only 50 out of 100, so here But who will be more basic if 50 Aquas come Obviously this will happen, this will be basic This basic thing will increase and it will reduce This is my simple explanation ok let me tell you more about them There is a confusion between both of them This is called weak base, no, both of them Strong Base yes but it is weak alkali what does it mean what does it mean Look son, listen to me, these solubility is not water There is very little of it in me now because in the water Low solubility means it is poor quality It is alkali, which means that it dissolves in water This is not happening so it is an alkali but This is a strong base, the meaning of strong base What is it, let's say for example its 100 You dissolved 100 molecules of these in water too Dissolve it, now only 100 of its 100 got dissolved and 100 100 of its 100 broken into ices Only 50 will dissolve but 50 out of 50 will be complete If we compare them when they break then There will be more like this - Aqua Jaan see It had 100 molecules, it also had 100 Both were molecules dissolved in water 100 of its 100 molecules dissolved and 100 100 molecules of were broken down in science So 100 - aquas this gives 100h - aquas He gave 100 if you talk about these two I will take 50 out of this and complete 50 out of 50 If it breaks, it will give 50 - Aquas will give it too he will give 50 also he will give 50 why this week Alkali is completely dissolved in water No, when it has not dissolved completely, as much as it should Complete breakdown If only 50 gets dissolved then all the 50 will get broken will get strong base but weak alkali so low Solubility in Water ok now look at the nature of salt Identification Katya came and his son came to us Anayar came to Katay and this one came to us Ammonium Acid Plus Sodium Hydroxide acid plus base acid plus base acid plus base acid plus base acid plus base this cutting so what did you make of this cutting and water along with it, now see son one more thing Understand where the nick part comes from Sunil Bhaiya Katak part came from the base Raja son Anayat where did this come from came from acid small things Understanding the Positively Charged Ion of a Salt from a Base the negatively charged ion is coming from the acid Positively charged ions are coming from the base is the negatively charged ion coming from the acid Positively charged ions coming from the base The negatively charged ion is coming from the acid Positively charged ions coming from the base The negatively charged ion is coming from the acid Did you understand what I said Sunil? so acid what we have is acid plus base it will give salt plus water that is If acid and salt react then it will be formed salts and will be formed together water is ok hclo2 if this went with the nayan from the cutting then and that comes from the acid right here is salt well what kind of reaction is this hogi raja see son this reaction will be double Displacement reaction because of cutaway noise is an exchange of and double displacement is three is of the first type in which a Insoluble solids are formed here No insole is becoming solid second acid plus base will give salt plus Water neutralization is neutralization. The reaction itself there is work finished done now this salt must be made Now look carefully what its pH will be. Son, if we use the same concentration and the same amount Taking the acid and base of I am 100 So what is this strong base? is strong acid strong base reaction If it happens then we will use this salt which will be formed We will call each other normal salt because If you neutralize it then it will be normal or else this The salt that will be formed will be called neutral salt Normal or neutral salt and along with Basically we will have water here finish strong acid plus strong base will Give normal or neutral salt plus Water Bath discussion is over This means what will be its pH level pH of this particular salt is equal to 7 Correct Let the second one come to us for example Ammonium Chloride Listen Carefully Next we have here is ammonium Chloride Ammonium Chloride Now carefully Look king, pay attention to what I say listen carefully son listen carefully listen carefully listen carefully Listen listen carefully listen carefully look at this son we have ammonium chloride carefully listen to me very carefully Now listen, what will be its acid and base? Sunil Bha, what did you teach us that whatever is cut There is a nick part, this is the cut part It basically comes from base and bases are vat Hydroxide Ammonium Hyd oid What is Katay basically, where is Katay coming from will be from The base is ammonium hydroxide second Anayar Anayar where will we get the salt from Keep the salt cut coming from the base ammonium is the cation of the base ammonium to What could be ammonium hydroxide? will be the base Where does Anaer Acid come from now Chlorine So is the acid hydrogen containing? If there are compounds then this will happen Our Acid Se Frozen acid so we have hydrochloric acid be acid Gaya acid plus base will give Salt Plus water done h s p nh4oh will give nh4cl p h2o Concept One: Now let's talk about the second one If here I put the same amount and the same concentration beans amount and same concentration same amount and same Raises the concentration of acids and bases if the same amount and the same concentration If I pick up the acid and the base here Listen carefully what will happen if the same amount And if I mix acid and When I pick up the bass, look what's here will be I picked hclo3 and nh4oh 100 ml hc1 ml nh4oh 100 ml and 100 ml of nh4oh inside 100 pay attention to my point about nh4oh from molecule Listen son, I am telling you this, brother, I I am telling you that my brother's 100 ml I picked up 100 ml I picked up this inside it It has 100 molecules, it also has 100 molecules Its molecules are 100 to 10,000 milliliters 100 molecules inside The first thing is clear about hc40 It is clear Sunil Bhaiya, now pay attention listen this strong acid this strong base No this is a strong acid and this is a weak base what does it mean Its simple meaning would be Sunil Bhai that 100 of its molecules will break down 100 h+ x will come out but here its Out of 100 molecules, only 50 will break If you don't get any X then it means this is a weak base Strong acid so what salt will we get here What salt will we find here? What salt will we get here? What salt will you get? Acidic salt If we get it, then its pH will be that will be less than seven Its pH will drop, it will not neutralize it If you can do this then the pH will be less than seven and It will come out together here basically water then ammonium chloride whatever is here its PA will be with us will be less than strong acid weak be V Gov Acidic Salt Plus Water Iska Jo the pH will be less than seven it will be fine Is Now let's see, let's talk about caco3 here will be a salt of strong base and weak acid caco3 will be a salt of strong Quickly identify bases and weak acids Let's take it in to our house go what's the matter let's let's let's Let's come to the comment section and see now hey, I can't see it from here a little bit where did my brother go Lecture my friends why did the chat freeze and what happened to you naughty boy what happened So far 600 children are sitting with me very good Dude very nice very nice what is the matter why is it not opening Bhaiya yes it is done now what will happen bhaiya yes yes Sir all is good good good good good come on it's fun it's fun ok it's done keep it like this will keep watching Brother please see this chat once Be salt of strong base and weak acid very good very good sat Aayushi Mazer Ratu Ishaan Kallu Kalia Abhishek Kallu Kalia Albert Einstein Nishant and ashwat kallu hey son kallu lallu pallu Kallu, are you not feeling bad Kallu Kale I am not feeling bad, the meme had come right? I am Kallu Kalia and you are the one who is meme wala are you acting yes nochi Boy Kallu Kalia come on now this is absolutely correct like For example I wrote Raja here son caco3 i wrote it here as if i accept it as king son h2o now you know the reaction Look, it's a simple thing, I got to know this did you also know that cutay nick Where will the salt part come from now? Where is Sunil Bhai of Katay Nick Part Salt the cut nick part will come from here basically the base Look brother, you have found out this that the cut part will come from the base, so this is our There will be a base that is calcium hydroxide good look anair what will come Basically, where will our acid come from? Now see, if it is carbonate then what is acid It is a hydrogen containing compound yes Sunil bhaiya this will happen basically h2co 3 add this h2 co3 and Reaction of calcium hydroxide here But this is what is going to happen to us basically what do we have acid this is what we have is basically a base this is an acid this is a base is acid plus base will give salt plus water brother this acid and this base react If so, this salt and this water would have been formed This is what must have happened, I put it upside down If we write caco3 water then its cationic The part comes from the base, i.e. Calcium hydroxide is an antacid, that is Carbonyls are our done, now let's accept that I use the same amount and same concentration I take acids and bases, what did I do? amount and same concentration of acid and Base means what I mean to say is that 100 ml I took this 100 ml I took this, it has 100 molecules inside it it has 100 molecules inside it it has 100 ml of this 100 ml of this 100 100 molecules in a milliliter 100 of its 100 molecules in a milliliter is equal to amount same concentration of acid and base Now I took my words seriously sun h23 what type of acid do i have Sunil Bhaiya this is a weak acid we have done Kar Weak Acid is what we have Sunil Bhaiya we have this one what did I do I told you the bass is strong, how is it strong base base is strong my friend hai weekly hai strong base weak acid so mere Brother, what will you write here for Salt? Weak acid is strong base so this is salt How will the pH become, this will become basic What kind of salt will it have, which is the basic salt pH will be and what will happen to seven There will be more together what will be built here But water then its pH will be between seven to what will happen will happen more than weak acid will be converted into strong base drink more than plus water is ok Come on son, ask this question quickly Son, finish the last topic quickly There is a salt form in ICSE 2021 By the incomplete neutralization of N Acid by a base see whose incomplete Neutralization is happening incomplete Neutralization of an acid by a base means We have an acid whose incomplete Neutralization is happening due to base So the character that will come inside salt will be It means that more acid will come out Acidic salt will be the end of the matter, hey brother acid Its neutralization is not possible Meaning pH will be less than sane's work The pH is going to be over, which will be seven will decrease if the acid is neutralised by the base If it cannot do this then the salt becomes acidic OK it is clear it is clear Come on my king play the instrument of question, write it down Please come once brother, don't forget your brother Don't go, Raja, don't forget your brother What's the matter raja beta very good oh my Raja Bajad Baja thank you so much thank you so much son Thank you so much for so much love and support Thank you for so Much and you guys are sitting here for two hours 35 Thank you so much for that from last minute This is a topic, we will finish it quickly in next 15 Method of preparation of salts within minutes which is given in our book of appet Discussion has not been given about the syllabus of 2025 in there is no discussion about the apparet us that we have inside him inside the apparatus I don't know specifically, we just need to know The Reaction and Its Types The first way is to make salts Direct Combination or Basically Synthesis Which reaction is direct combination or Synthesis Reactions Meaning synthesis reaction or combination Reaction you got from me in class ninth I have read that by reacting with multiple reactants We will make a single product that is yours Combination or synthesis reaction now see King, listen to me carefully, my iron what do you have iron suppose i have one Silvery gray colored powder is silvery I have grey powder and accept this raja I have a yellow The colour of the powder is sulphur powder which is yellow I am understanding the color of silvery grey color This is powder I have yellow powder for them I heated it and it turned black. will get converted into iron sulphide Ok brother, now what do you want to understand from this? Beta single product from multiple reactants Whether single reactant is formed from multiple reactants or not Multiple reactants formed or not Is a single product made from this or not at all It is made of silvery grey iron powder The reaction will be with yellow powder and sulfur If you heat it, a single product will be produced that is iron Sulfite means salt to us if I want to make this is a salt right this is a Salt is the first way to make salt we have combination or synthesis reaction Multiple reactants form a single compound Now for example if we have there's carbon dioxide and we have It is calcium oxide, if we will make calcium oxide react that if I make the reaction happen No heat with dioxide Here, if the reaction of calcium oxide If it happens with carbon dioxide then it will give me calcium Carbonate again this is a salt, understand it If yes then you should understand that multiple Getting a single product from the reactants that means it is apple of a combination of One of the synthesis reactions is to form a salt The way is through combination reaction You can make salt, okay there is another way By displacement reaction, that is, any to get the thing replaced or you ICSC This is also called replacement reaction so bye displacement reaction and bye we can do this replacement reaction Like we realized this a while ago that we have zinc because zinc Acid has more reactivity than hydrogen There is more hydrogen present inside than It will displace it and make it zinc Chloride and hydrogen gas will be formed Correct This is because the reactivity of zinc Zinc is more hydrogen than hydrogen It will displace and form zinc chloride plus hydrogen gas so this zinc chloride is nothing but a salt like that what do i have Silvery grey I have an iron nail I am going to call it blue colored copper sulphate I will put the reactivity of iron in the solution Because it has more displacement than copper will make sulphate of iron and along with it reddish brown copper what is this all salt yes it is brother this is also salt this is also Salt If so, construction of salts displacement It can also happen through reaction, like here Zinc chloride is formed here basically iron Sulphate is formed so this is salt that is formed displacement reaction is going on One to one and by double displacement reaction example of precipitation precipitation is basically What happens to the insoluble substance after the reaction? Becomes quite solid in the next chapter These words will be useful in analytical chemistry Solid After The Reaction means after the reaction, a formation of insoluble solids There will be three types of double displacement reaction The first type is precipitation and the second type is Neutralization is the third gas forming what happens in precipitation An insoluble solid is formed is like for example for example this What I had was sodium sulfate and this what do i have barium chloride if I get their colorless solution here water is a colorless solution Both of them will mix well in me I would take their colorless solutions here's what I have this is basically the cationic part and this is basically the anair this is basically the katay nick part and this is basically the The analytes are sodium chloride barium sulphate so what is barium sulphate basically White ins is solid no what is it my friend white insoluble Solid is a white insoluble solid i.e. what is it Chloride build up in the precipitator If it goes then you should understand that it is double displacement reaction means the type of it Precipitation can also lead to formation of salt Katay Nayas' insole could be exchanged Formation of a salt The construction of the press has been done here gaya this is a Salt is salt, that's absolutely correct for example if I have what here I have some copper sulphate here I have a blue colour solution Cationic part or anionic hydrogen This cationic part is sulfite gas. Anayar Katan Sanay will exchange copper Black insoluble sulphide is present here Solid will become a black insoluble solid which we What are people saying This will form sulfuric acid along with If it is built then salts will be manufactured here again It is happening, yes it is definitely happening The fourth type will work is double displacement in the reaction itself that the neutralization reaction from we made from combination reaction Displacement is made double Formed by precipitation in displacement By double displacement neutralization If we make it then we will also get it through neutralization There are two ways, the first one is here and the second one Here's the method, now what do we have here If our acid reaction is near, then water If it is done with a soluble base then this type of Titration of the neutralization reaction People say and if our acid Reaction which occurs with an insoluble base If yes then this is only and only neutralization It means in double displacement What happens in neutralization of acid with water soluble base i.e. alkali The reaction is of acid plus alkali If the reaction occurs, it is called titration of acid Plus if there is a reaction of insoluble base then only neutralization now titrate it yourself Chemical itself is a very big topic If you come to equivalence then I will explain it to you in 11th class But I gave you some idea Give Now look what you have here is hydrochloric acid that is cutting nain This is basically our sodium hydroxide Nearby is the Katan En Katan Ana exchange will do this cutting with anan say that will Make water and this Katan went with Anan then This means that sodium chloride this is done ji second one Basically this is what we have cut out the nick part and there we have it anair here we have it Katay Nik Part and there we have it Anaar this is an insoluble base but the base is Na this is a base not an alkali copper I told you that oxide is a base and not an alkali Just a while ago this with Kataya Anayar What did we make with this pineapple? Look if there is hydrochloric acid nearby this is a cataclysmic part this is the anak part this is the katak part and this is basically the other part okay so here This Katan is being exchanged for Katay Ana When I went with Sanan, I became h2o this Katan Sanan When it is mixed with copper then it forms chloride of copper Again here this is also salt and here What is this also, it is salt in both cases what is salt if yes then here to make salt There are two methods of acid neutralisation Is the reaction taking place with water or base or acid The reaction of insole is getting formed from force base Salt remained in both cases after that the last of the double displacement type i.e. gas forming reaction There are three types of double displacement: Making the insole force solid i.e. precipitation the second acid plus base will give salt plus water neutralization reaction that is called neutralization The third is basically the gas producing type That means gas will be formed, now we have read this that metal carbonate or hydrogen carbonate what if the reaction is with acid If salt is formed then water will be formed along with it And if CO2 is formed then salt will be formed I read this reaction to you exactly Similarly if we have sulphur of metal I am remembering if the sulphide of metal or The metal will have bisulphate and the acid will If there was a reaction then SO2 was being produced salt h2 and so2 if the sulphide of metal is And if there is acid then we will have salt and hydrogen sulfide, these three reactions I am missing the metal buy of carbonate or metal hydrogen carbonate If the reaction is with acid then it will form Salt water and carbon dioxide metal Reaction of sulfite and bisulfite with acid If it happens then what did I tell you about salt juice h2o p so2 and then I told that if The reaction of metal sulphide with acid will be So what will be made, we will have salt and Hydrogen sulfide gas will be formed oh yes or no raja will you play it or not Baja ji absolutely That's correct! If you understand this much then let's do it once Brother, I definitely felt it finish the work if you understand this much I have missed my point so please write it down to the Comment section that you have understood OK Is Let us write down the income once, write it down quickly Enter the comment section, what's the matter? What's the matter? All right my friends. I hope you understand all these things I was coming, you were enjoying it I did all the things here in my dear brothers and sisters finish I would like to present this lecture and say that Sunil Bhaiya was with you and will remain with you till the end The physics guy is with you, see a lot I work hard for you guys I want you all to work equally hard here. Do what Sunil Bhaiya works hard for you You too are working hard Please understand, there is the next chapter Analytical chemistry will settle the deal We will give it to you, we will drive you away, okay, right? don't take tension i hope so You understand everything, and Everything seems easy, anything It doesn't seem like it is difficult, if it seems like it is Don't worry Sunil Bhaiya, everything is with you Looks simple and easy it will look ok it is clear it is clear hey dun dun dun ok so see you next Till then take care of yourself in the lecture Be happy, stay the same and always say Jai Jai Physics wala Jai Hind Jai Bharat Vande Mataram B
