Hello children how are you I am fine I will ask you one thing honestly that acid Basis Salt How many videos have you watched Summary video for lots of one shots Look, now I ask you to Which acid is present in string? I ask you now who is in the nettle sting Which acid is present in tomato? Which acid is present in tomato? happens I ask you right now of lemon juice inside the universal indicator I can't remember what pH is If you had revised it once, I would have remembered everything what is the formula of baking soda What is the formula of bleaching powder sir I want to see the notes again and again, oh what is the use of studying that if you had to look at the notes again and again before the exam because you Till now son I have seen one shot of yours I have brought the gun shot gun shot anytime The target is not missed after this gun shot I can tell you as much as I can within one and a half hours I will teach you, you will remember each and every thing It will remain on the tip but along with it this too remember that if you are in cbse board Or are you on any board where NCERT is followed in this one and a half hour Anything in your exam from outside the lecture Not a single question will come from outside this Your exam paper cannot come 100% here This is not a regular one shot, that this it's important read this it's important Read this, do this, don't leave this gun It's a shot, I'll teach you and make you remember it here I will also get my practice done here because I am 30 More than this question from previous year Within 1 hour of lecture you will I will make you practice for 30 rupees Complete NCERT within one and a half hours I will teach you and make you remember it too Wherever the concept of a son appears, there I should not even explain the concept to you I will only give tricks everywhere, I will give the same trick Where there is a need to remember, where there is a concept I will explain the lecture to you in a better way Take a good look at the notes and then download them Always do it and revise it once I will remember brother, let's start first You all know what cheese acid is. Acid may be a substance which When you add water to the aqueous solution when you put that what does that give gives h+ is as the only positive ion in I did not understand the aquas solution, leave it I will explain this thing in more detail later, leave it for now Just remember what acid is hc2 Hands get damaged and the acid turns blue What is this litmus red thing? We will tell you later acid gives h+ iso solution next We will catch it, let's move forward, now we have the base Brother, what is base? Base is such a substance It is bitter, meaning sometimes bitter soap I have licked the base in soap, it is made of Sir, I am hungry, you will eat the powder, I will move away powder when you eat do not eat it when a little Many people would enjoy testing it If you test Nirma powder in the refrigerator then you will find that Kalwa sa taste good soapy in touch Turns are like soap in red litmus Blue: This turns red into blue, it's the reverse Increases Hydro Oxy Line In Aqua Solution acid h+ and base - these are from above I am telling you it is not at all hard, but now to remember h+ from acid and h+ from base oh-my-zsh oxide k potassium hydroxide nh4oh ammonium Hydroxide, these three bases are strong for you should be remembered from na-k nh4oh ammonium hydroxide these big They are strong but these are a bit weak then magnesium hydroxide calcium hydroxide and then some oxides too mgo2 caoh2 Okay let's move ahead now brother this indicator indicator tells us whatever The given substance is an acid or a base You must have remembered many times that litmus Everybody remembers the blue in the base Turmeric turns red in acid Actually there is yellow in the base due to red acid I'm in a bad situation here, Phenol actually Pink in a colorless base is a must remember Simple line, you have to remember what is labor There is no labour who lifts the goods, we They are also laborers, they are carrying the burden Life's Labor Tra Popcorn Popcorn eat labour try popcorn with mayor city A laborer carrying bricks with the mayor of what is he eating popcorn with E quality came in the society with the mayor Labor Imagine Will Try Popcorn With The mayor is over, brother, it's over now let's start Do Labor Labor, I teach from here Labor L means litmus B means blue R means red see litmus blue red remember one thing first I will catch the base then the acid will catch the base first Then let's try the acid litmus blue red Turmeric Red Yellow Popcorn PPC Extraction Is Finops Pink Colourless First Base Then Acid Mayer Methyl Orange Yellow Red Ball Recalled Labor Try Popcorn With Mayor Labor L B r litmus blue red try it with me talk Try Turmeric Red Yellow Popcorn PPC Phenol Pink Colourless with Meyer If methyl yellow red is clear then it is called this Trick to remember you forever First there will be the base then the acid, never again Bhoolge Labor Try Popcorn With Mayor Chal Never see CBSE questions after this I will not forget brother, this is the first question CBSE 2023 asked the question out of the The following compound or compound will turn the Finley Solution Pink Fino Labor Tra Popcorn Pop Corn PPC Fino pink colorless and son what is first in itself tha base then acid phenops solution pink who does pink, if someone does base then he does it himself We have to find the base, so acetic acid is Hydrochloric Acid Calcium Hydroxide Base nao2 both the answers are correct right magnesium hydroxide calcium hydroxide it's all base clear o is next acid h+ base o general is hard No, don't write it straight away in your general mind. Next CBSE 2023 N Eq Solution turns blue litmus red what did you do son Blue litmus turned red, what will happen? So the acid turned the blue litmus red Wala Acid which of the following solutions When added in access wood reverse the change What's the change? Blue has turned us into red. Turning Red Back to Blue LBR Labor will you remember what we have to do back Reverse the Change takes us back to Red to Blue who will make red turn blue then base will do it wash your lemon juice and lick the acid now We had a talk so this has become acidic Who needs base magnesium hydroxide? Raha base mohfw.nic.in Let's move ahead, what's next son? CBSE 2024 now son one question you You will also do your homework yourself when you take notes If you download it, I will write the solution in it But now you have to do it yourself too Important Points to Remember Litmus Solution is originally Purple in color when there is no acid and base When neither acid nor base is added to litmus If you do it then it becomes purple and it becomes litmus Blue in red base, red other in blue acid wise purple good pure h2o has no effect on the colour of litmus which is pure water There would be no difference on litmus, neither water nor acid isn't it, there is a base, there is something neutral Litmus is a natural indicator These things are extracted from a plant Remember that litmus is actually purple Pure water has no effect and litmus It comes from the plant, brother, let's move ahead now is all factory indicator see litmus phenol Turmeric what was all this brother labor try Popcorn with Mayor Limar Tri Turmeric Popcorn Phenol with Mayer A means methyl methyl orange, these four What were they? They used to change colors so whoever could see them It will be visible to the one who cannot see it This indicator is all factory indicator What is the smell or odor of something It tells whether it is an acid or a base Simple substances whose smell changes in acid And the basic medium changes its smell It is clear in acid or basic medium You have three examples, one is your onion onion second is your clove clove oil and The third is your vanilla essence, these three things that dissolve in acid If you put it in the base then it will smell What else generally happens to these three The smell remains in the acid after going into the base There is no smell, no retention in acid Loose smell in smell base then it is made in acid If it is put in the base then it remains in the base It's the same smell that onions smell, isn't it? The same penetrating scent of clove and vanilla and put it in the base, all the smell has disappeared now If you have to remember then all the factories are available from here The word factory is visible, now let's imagine Let's do a factory, a big factory I went to a big factory and I are you a small kid, going to a factory? Will you eat vanilla ice cream sir one vanilla Giving ice cream is our different style Valil will add some onion to the ice cream And stick a clove in it and then eat it Look, you went to a big factory, what happened Manga Vanilla X Cream Factory All what did the factory ask for vanilla ice cream vanilla What essence did you add, long clove oil and what else I added onion and it became onion look at the finish this is a vanilla ice cream Vanilla essence, cloves, clove oil, onion planted onion and where is all this from the factory All factory indicators inside brother Let's see the CBSE 2023 questions Asks to select a pair of all factories What all is there inside the indicator brother factory This is vanilla ice cream with clove oil in it and onion is onion then clove oil and vanina Essence is right Onion is turmeric gone wrong Clo litmus paper gone wrong methyl orange This is wrong now the mentally challenged student Brother who cannot see CBSE in 2020 asks the question that if someone If it is not visible then how can it use the indicator Use the fragrant one i.e. all The acid base is the end of the factory Indicator preferred by him the child whom I cannot see what is the acid base for it The indicator will be clove oil, not litmus yes clove oil clove long sahi hai all Factory indicator, brother, let's move ahead Now behaviour of acids and bases in water when We first put the acid into water I had read in the slide that acid was added to water It gives h+ ions as soon as it goes into aqueous solution what gives h+ acid produces h+ ion In aqueous means water aqueous solution So don't pour h2so 4 in water like that do not pour it all at once but slowly otherwise When h2so was put into water, did h+ ions emerge? Two ions got removed and sulfate ions got removed hcl-insys The acid will not come out, what do you have to remember produce h+ ions in aqueous solution here It is important that the acid always gives H+ No, where will you give water in aquas solution If you go inside and take dry AC gas then It does not have h+ Secondly acid aqueous solution there is only one solution can give a positive thing that h+ cannot give any other positive thing a I can only give you positive thing ch h+ see this I had written about acid in your definition There is such a hardcore definition in the syllabus No, that's why I left it anyway Look at the time, it was written A Substance That give h+ as only positive ion in aquas Any other solution in aqueous solution Acids cannot give positive ions, only one only positive h+ can give negative All negative Many positive One h+ Identification of Acids Acids having h+ in water identity there's a h+ in water okay that's it No protest is not at all tyranny but about acid Identification h+ in water is clear and if water if it is not there then it is not h+ then that thing is acid No Acid has no power without water Brother, water is as important to us as it is to us Separation of h+ and smid for acids Sulfate ice cannot happen without water Identifying acids without h+ in water If there is no water then the acid cannot be identified, let's move on h+ of acid increases now which acid has h+ It comes out, look son, pick up any acid what did you pick up here h2so h+ hclo3 see how nitric acid will break down h+ and HNO3- ch3cooh how will acetic acid break down h+ and ch3coo - is it necessary to learn how to break or not you will learn slowly h2co 3 carbonium ion need to remember all this No, don't worry, I am telling you that acid All acids go into water and remove H+ ok now what is written h+ of acid combines with water to form h3o on hydronium ion Now the h+ of the acid which is released does not come out alone he stays alone not single like you It is your compulsion, not his acid As soon as the H+ comes out, it gets connected to water h2o to h2o one h went what happened h3o and it is added on top it is called plus Hydronium ion hydronium ion h+ of acid do not stay alone i am not like you that alone stay and you too are under compulsion brother h+ off acid combines with h2o to form Hydronium ion is very simple water h2o put an h+ h3o and the plus sign above so v from acid gives hydronium ion and h+ aqua ion now this h+ aqua is many times Friend, who writes such a long story again and again? h+ in acid water no h+ aqua hey sir You changed your statement, yes brother Because h+ will never be seen there We think that we will not get it at all, h+ You must have come to understand what we get is h3o plus hydronium ion now Who writes hydronium repeatedly, so big So we write h+ aquas, that is h+ aquasal inside water so whenever someone writes h+ aqueous h+ inside whom son inside h2o and that means h3o then either you Write hydronium or h+ aqua acid h+ aquas in water this h+ aqua ion and Hydronium Ion Gives Common Properties to all acids This is the common property of all acids. Like they're sour, like they're blue All these things turn litmus red Where is the property of acid coming from which When they go into water they release h3o+ ions or h+ gives aqua ion and no other And we will not give any positive ions, come on brother preparation of hclo2 The reaction here will be double displacement D In the first chapter, you read double Displacement then na2s o4 with cl1 hclo2 iso2disc We took this H2O gas out through this pipe And what did we plant? Now we planted two things. Pay attention, that is why we are teaching experiments that's why we called H2O gas as dry blue Tested on litmus, dry meaning no water no if there is no water then it is not h+ will give it and if h+ is not given then it will have Acid has no property so dry Will this make any change in blue litmus? blue lit mus stay blue son hey sir this is acid hey water Babu, where can you understand the worth of acid without it Understand this gas itself as a huge acid I wondered who had the dry blue litmus there was no water in it no change then he came again my litmus most means son this is wet water As soon as I brought water I brought it for s did we get water and what did we extract? h3o p hydronium or h+ aquas and same property to acids This is what I give h+ now as soon as I get moist Son, the acid has turned red in color Property came so I taught experiments This goes to explain to you that acid Acid without water is not the end of the matter dry litmus paper is clear no change weight water h+ colour will change acid is formed it got cleared with water ok here is one This thing is asked many times that this cacl2 why did you use this pipe here c Now why are we doing this experiment If we have to remove the dry AC and check it then we have to You want dry here only then check it You will find that yes, you must and what happens in it so cacl2 is calcium chloride This is your dehydrating agent: water if it sucks then What hc2 does is it sucks out that moisture so that the experiment can be done properly cacl2 takes away any moisture present in h so that we can conduct this what is an experiment this is preparation of h how made na2s o4 come on brother move forward good one Look, I have written this reaction, write it down too where will hclo2 connect and what will be formed from h2o h3o p is gone and what came out son sa ma and if there is only gas and no water then this There will be no reaction, no H+ will be released Let's move ahead, see the next son question is coming 2023 hydronium ice How to make R form by the reaction between No sodium hydroxide and water No Calcium Chloride & Water Hydrogen Chloride Gas And Water Yes hclo3 o+ hydronium ises cbse 2020 Son, please do this in your homework in a simple way The question is create a labeled diagram to show the Preparation of Hydrogen Chloride Gas in Who will you make the lambi out of, son? You will make a diagram with naclo4 concentrated make it and put it down h s sorry naclo4 test the gas evolve first with dry and then with wet lisam to dry If you do it with no change weight litmus What will happen when blue litmus turns runny wet water has come in two cases Litmus paper shows change in color in wet state The Reasons for Becoming an Acidic Exit Character by Dry hclo2 x ion will not be formed this is the answer and hclo2 ion then see dry hcl.com ion or h+ aqua ion so it has Acidic character is dry Now let's talk about bases, what do acids give if they go into solution then they form h+ aqua or h3o Hydronium Bases Go Into Solution increase the concentration of O minus ions or you can say this simply bases give o can you say mine ion in water can you say It is not correct by the way [Appreciation] na0 - look there is a strong base from here k potassium hydroxide k+ o mine when water When put in, this does not happen automatically as a hole in the What did you put in the vice and what did you get in the water? If the vein ions and mg2p are cleared then going into base solution - ion acid h+ Aqueous Bases - X Now What Are Alkalis hey look some bass go into the water and get solly There are very few bases like this Which ones do you need to remember that you should keep in mind while in water? Soble bases are called alkalis, some bases Are water soli force these are called alkali which There's a sobble in the water na4 sodium hydroxide potassium hydroxide ammonium hydroxide in Completely soluble in any water except no it is a little like these these Magnesium is a partially solid force Hydroxide Calcium Hydroxide barium hydroxide what is it It is partially soluble and slightly alkaline This is the best among all the pure alkaline water So, if you remember then take the example of alkali This is what you have to write in the exam such as zinc hydroxide ferrous Hydroxide Copper Hydroxide In Son, if I meet anyone else except him then he It is not alkali actually so group one whoever meets group two, but now So if you hold this much then sodium Hydroxide Potassium Hydroxide Ammonium Hydroxide This is very useful for you Highly water soluble, low in magnesium calcium barium after that no one else will go brother Let's take the question, what is this as well CBSE did not write Sodium Hydroxide is termed as alkali sulphate Hydroxide is not brother sodium Hydroxide is called alkali but Why is it not called ferric hydroxide? Because sodium hydroxide is water soly Ferric hydroxide is not water soluble Sodium hydroxide is a strong beige Val no it is sodium hydroxide is a base which is sable in water while ferric Hydro is also a base but it is not soluble in water come on brother what is next acid plus water is a highly assorted reaction let's go good There was talk of pouring acid into water It was important to always keep in mind that acid should always be mixed in water Never pour water into acid why pour it because acid and water Reaction son, a lot of energy comes out There is a blast, a highly sorted reaction It is about acid and water so it is always ad, it is always ad Acid to water, how will you remember little by little All those from Kanpur who might be relating to this You must have seen ATH ATW in cities acid to water or acid to water sometimes water Add the acid drop wise to the acid slowly Pour it into the water and stir continuously Always add acid slowly to water with constant stirring always add acid to water drop wise slowly with constant how to insert steering drop wise son Why sir why acid to water why not water take a bucket and put it in the acid and read if Water is added to a concentrated acid concentrate I mean it's just a lot of the best stuff in it Acid is the heat that generates may cause the mixture to What If You Splash Out and Cause Burns Son, suppose we poured water with acid There is acid inside, son, it is a very reactive thing If you put water in it then it can cause asort reaction splashed all the acid came out of hands Brother, acid got applied everywhere in the bath, I got burnt brother. no the glass container can also break due Two heat given out along with glass container It might even break due to so much heat You don't always have to say goodbye son, you have to remember ath a tead acid to water drop wise with Why constant steering because acid The reaction of water is highly assured if water is If put in acid it will splash out and the glass beaker may break ok brother question Check CBSE 202122 Term One result is 21 22 term one concentrated h2so 4 is Diluted by adding drop by drop Tell me diluted means adding water How to dilute means adding water to something dilute oth acid to water acid to water with constant steering aath chal bhai What's Next for Acid and Alkali What is the relation between electric current and brother Whatever happens, remember one thing Electricity flows through the solution only when Is there ice in the solution? If there is ice, then What is acid which gives H+ ion and what is alkali They give because water is soly - ions in acid and alkali solutions If there are ices then electricity will flow through it Solution: Son drains electricity only when h+ in acid solution containing isoenzyme no hydronium base on aqua or h3o in alkali solution because alkali In solutions of soluble in water - the ions will remember the electric current through the The solution is carried by eyes found out How do you get ice in solution solution of acid hc2 Resolved Do Not Generate Ion and Hens Do If you do not conduct electricity then your son organic compounds that are This is also organic, it breaks down ok then whoever has the money will conduct it Electricity is our next option brother topic reaction with metal ok how Acids react with metals now acids We study the properties of and the properties of bases. so first we have to do this You will have to remember the Priority Series many times You must have seen that this is a priority series, right? So remember it the way you want This time I told you another trick Today I will tell you the second one in my first lecture. Katrina asked for a car Over hydrogen They react with acids and release hydrogen Metals react with acids to release gases to give salt and hydrogen and son here Which acid will you take? Dilute acid Pay attention to which metal The hydrogen is above the dilute acid react to form salt and hydrogen gas This is a way to make hydrogen gas also available let's zinc plus dilute hclo2 salt is removed and hydrogen gas is formed There is also an exception to this, that Nitric acid does not do this reaction, but it You will read it in chapter three, don't worry now Listen carefully to whatever I am telling you. I will teach you everything in the chapter, one by one from the board There will be a question, don't take tension, don't say this In the comment that Sir I don't know the third I will teach that in the chapter on metal know metal alcl3 Son, do you know the valency of aluminium? cross multiply chlorine by -1 Lia plus did the hydrogen gas escape You all have to balance them as well by reacting I think this is 6cl balance see c+ hso4 then son copper sulphate The valency of plate sulphate is -2 then it will be cut cuso4 plus hydrogen gas no that's it The focus is on hydrogen hydrogen gas from dilute acid we will take it out and display the bottom one a little You will find which reaction you have to this chapter You must have read in the forest, whose example is this The displacement reaction is more Those who are active are less reactive Let's display it, see where the zinc is right above hydrogen in the series Where is aluminum in the series with hydrogen Above is correct, where is copper in the series Under hydrogen there is no beta reaction If it happens then metals are chh r ab hydrogen The hydrogen atoms that are above the acid are If we combine salt and hydrogen then Son this will give reaction this will give iron also Everyone will give magnesium, everyone will give copper, no You will give mercury silver but it will not give clear okay okay now see this preparation of What is the process of hydrogen gas We read it because it is given in NCERT so what do we do son we are one dilute sulphuric solution inside a test tube acid so you took an acid and zinc Gals means you took zinc metal zinc Look where it is, look where it is above hydrogen The reaction will take place on hydrogen Metal Plus Acid Gives Salt Plus Hydrogen is clear, look metal plus acid salt plus hydrogen is gone so ours zinc ps h2so 4 dilute what is made znso4 This is a white colored powder, it is called white I say withdrawal, son, whoever Salt Cay have sulphate family so4 this family which it happens it's called withdrawal family okay If there are withdrawal symptoms then make a white withdrawal and Hydrogen gas is now formed One thing I told you about in the first chapter I had studied, I tell you again and again, Hydrogen The identification of gas is that it burns with a pop sound yes like this it becomes i amja nahi pop It extinguishes the sound and a burning candle It gives a pop sound and is made by itself but he extinguishes the candle because he He himself is a const force but it is not a supporter Off combustion will burn itself but does not let it burn If it is okay for someone else then why zinc granules I use it, the word Granal is written Because son granules means small pieces More surface area cut into If it is found, the reaction is faster Gives most surface area the way you home You grind sugar and add it in big pieces, right? do not put small lumps so that more If the reaction found in tea is more then Zinc Annals gives more surface area znso4 is a white color salt cold white withdrawal h2 gas burn with pop sound and extinguishing a Candle is a must but not a supporter of combustion ok the candle will light up with a pop sound will solve the problem brother let's see the question well there is another one reaction of base so you I read about metal, sorry, read about acid What does the reaction of acid with metal give? is made up of salt and hydrogen and those metals which Now base and metal should be above hydrogen The reaction is not so popular, just one The reaction is further in this chapter of yours will teach you what is in the next chapter Reaction of sodium hydroxide with zinc It would react with the base metal in the same way is like the reaction of acid with metal like from acid and from base salt and hydrogen Now remember its salt is sodium If the reaction between hydroxide and zinc takes place then will it become na2 zno2 sodium zincate and what else How will the released hydrogen gas burn with Burn a Pop Sound and will extinguish the burning candle and so on sodium hydroxide plus zinc what is made of na2 zno2 and hydrogen so base plus metal salt plus hydrogen acid plus metal salt plus hydrogen na2 zno2 it how to remember naat jana how to remember naat jana naat means na2 naat jan aa2 is it ok See, a question regarding this has also been asked when CBSE has come in 2024, Sam has come Metals React with Acids to Produce Salt and Hydrogen Gas Illustrated with An example of how you will test the presence off this gas you will do your homework is a If you want to show an example, give that very example Give example of zinc plus dilute h2so 4 give what will come out znso4 + hydrogen how will you test the presence of this gas Burning candles will be brought by pop sound and then it will extinguish when 2ml of Sodium Hydroxide Solution Is Added two few pieces of grated zinc in a The Test Tube and the Form of the Reaction that Occurs can be written in now what is sodium I took the hydroxide and I took the zinc. reaction na2 + zn20 2 na2 zno2 and hydrogen gas so see which one is nat h2 na2 zno2 plus hydrogen gas this one This is also a reaction but look at the water in it The hydrogen is released, move ahead brother Let's move on to what is neutralization now In neutralization, acid-base interactions collide and form salt and water It is very simple, acid plus base gives salt plus water so we took an acid hclo2 came out from here - what is the acid from here gives h+ base what is here aqueous from this - what came out h2o h+ - h2o And what is left then salt plus water acid plus base calcium hydroxide base ase from here son h+ from here oh2 ok from here calcium from here The valency of calcium sulfate is also two sulfate You can also check your caso4 balance no acetic acid ch3coh magnesium hydroxide look here like this h+ its this don't take out the h, it never comes out, remember Keep this one from the side h+ and from here oh2 now the valency of magnesium is son + 2 and ch3co- has one valency ch3coo- if 1 goes there then mg2 will go there and if 1 goes here then mg1 And this is called below ch3coo No need to remember magnesium acetate Acid plus base gives salt plus water Why does this happen? Because the acid has h+ of Aquos Base oh2 the liquid is clear brother let's move ahead Are Now what is the reaction of metal oxide with Acid Now metal oxide when reacts with acid If she does then she gives some salt and water it seems like I heard it So Dash Plus Acid Gives Salt Plus Water Dash Plus Acid Dash Plus Acid Gives Salt and Water So what is this thing, something in acid Add salt and water to form acid plus base So son, what kind of metal oxide is it? Generally metals are basic in nature Magnesium Oxides Are Basic in Nature oxide zinc oxide copper oxide Calcium, what is this basic metal The reaction of oxides with acids is the same There will be a reaction as clear as the base Copper oxide is in your syllabus reaction with whom plus acid give salt plus water and copper How is chloride with blue green color Water came out in my mind, how will I remember Black cop on ox who is black They are cops, meaning those who are black yes we don't have any black cops here There aren't so many, they are present at some places Such black cops are seen a lot in America There are black cops on ox in movies etc. We also see a lot of doing here Colgate Green Blue Color To Black Cop On ox cop os copper ox oxide what color son black what are you doing son colgate chlorine which color is green blue color so what happened to s cl2 colgate Look at the chlorine green and blue color Did he hold a brush of green and blue color I gave you something in your hand like this You can remember things otherwise you can memorize them It will happen son so on whom will the black cop sit he is sitting on an ox and what is he holding What did they get from Colgate here, son? What color is chlorine? Blue Green Color look you will remember it yourself let's go Black cops try to be like this I see black cop on ox copper oxide He is sitting on a black colored ox, what else Have you caught a coal gut? Which colour is blue coal gut? That means chlorine is blue green in colour and copper is blue green in colour Chloride Blue Green Clear so remember it like this can work brother generally metal oxide r Basic in nature because they react with acids I told you to give salt and water I said that basicity is achieved by reacting with acid Salt and Water Now see the next reaction Non metal oxide with base gives salt and Water now tell yourself what is in the base I added salt and water came out, what kind of thing is this? If it is acidic then it is a non-metallic oxide Acidic nonmetallic means oxides of sulfur oxides of nitrogen oxides of carbon You can remember like this, generally not always Generally sulfur dioxide sulfur trioxide carbon dioxide nitrogen dioxide is a reaction of carbon dioxide plus calcium Hydroxide what happened to you son non metal oxide what happened to base Nonmetal oxides react with bases to form salts and if water is there then what will become of salt caco3 calcium carbonate and what will come out h2o Water Calcium Carbonate You may have seen it sometimes called limestone Have you ever seen it called Chowk? Does it exist in different forms? There is a lot of effort in building construction too is used Generally nonmetal oxides are acidic in nature because they react with base to give salt And the water is clear, let's go next now. Reaction of Metal carbonate with acid to metal carbonate na2 co3 when it reacts with acid carbon dioxide gas is released and its Except the same thing salt and water then metal Carbonate with Acid Give Carbon Dioxide Salt and water is good, similarly metal There is also hydrogen carbonate hco3 - carbonate is co3 2 me hydrogen Carbonate is also called bicarbonate. hydrogen carbonate or bicarbonate hco3 My, wherever this carbonate thing is things go near metal whether bicarbonate carbon dioxide what does the rest of it emit were salt and water let's see hclo2 co3 is not in bicarbonate + 2 it happens sorry -2 it happens u came here na1 So what will come out here, son? It's a new thing Carbon dioxide will be clearly remembered make salt what will it become na2s h2so 4 + sodium bicarbonate bicarbonate is hco3 -1 na1 becomes equal to nahco3 sodium What will the bicarbonate come out one so what remove the carbon dioxide and turn it into salt n na2 A4 what else do you remove, the water is clear now a property of carbon dioxide You have to remember that carbon dioxide When we put lime in lime water we get lime Calcium in water hydroxide then it becomes milky White precipitately water is lettuce from this i lime Water, in this you assume carbon dioxide What is Pour Lime Calcium Hydroxide If you put carbon dioxide in it, how will it be son it will become milky The white precipitator will make the insole feel a little heavy will be formed but if you add more co2 to this solution put it in access put a lot of co2 in it I keep putting more in let us from you access put co2, we understood this here co2 is put in lime water if you put co2 in access Give it to me son, the milkiness disappears Milkyness Missing Milkyness You must remember that it disappears what would happen is that if some gas got into the lime water and Lime water became milky then if that gas is removed and put a lot of lime in the water Milkiness Disappeared dioxide and its reactions this is what you have to remember First look at the reaction of carbon dioxide We added this reaction to lime water I just saw the non-metal oxide base reaction with salt and water then calcium Carbonate became white PPT precipitately it is force son this is ok and water came out with it now when it is made What carbon is added to lime water? dioxide became milky when it got more Add carbon dioxide, that is, now this what is milky solution is there and co2 in it so first we added caco3 water into it and then added co2 If added, it becomes calcium bicarbonate c Ba to c son see what is valency 2+ and bicarbonate hco3 -1 so this comes here to here calcium bicarbonate which is water Soli Bal is clear Solution Soli Bal in Water Milkiness Why does disappeared dioxide look milky? If yes then you should remember these two reactions We added lime to the carbon dioxide what is the difference between co2 and water Calcium Carbonate and Water Icy Calcium If you add more co2 to carbonate and water then What will happen to calcium bicarbonate which is sable milknet We have also given the disappeared in NCERT what did you do son here sodium carbonate took i.e. na2 co3 and dilute hclo2 gives salt and water then co2 Removed naclo3 now this co2 went up take this co2 what did we do with calcium Calcium added to hydroxide solution What is hydroxide in lime water? what will happen if you put it in lime water turn milky and if more carbon If you keep adding dioxide then you will get milkiness It has disappeared, the question has also come up about it cbse 2023 when sodium bicarbonate Carbonate is reacts with dilute If you want hydrochloric acid then son be it carbonate or bicarbonate from acid If it reacts then what will it give co2 gas the gas What will happen if carbon dioxide is evolved it turns lime water milky cbse 2023 Another question is an experimental setup in which on passing the gas produced in the Reaction in the solution x The solution x First Turns Milky and Then Colorless Explain whether you have taken sodium Carbonate is visible and what did you take is dilute hydrochloric acid then what is carbonate and hydrochloric acid son, co2 gas will come out and this to whom did you pass the solution x what is this will be son it must be lime water, he said explain it you will do that carbon dioxide brother when If this reaction occurs, carbon dioxide gas is produced what was the solution x it was lime water when Carbon dioxide goes into lime water If it is, then we get calcium carbonate from lime Water Turns Milky and Carbon Dioxide If you add then calcium bicarbonate You will have to write that reaction of hydrogen Milkiness You have to keep disappearing, next is strength of acids and bases so let's do this little thing Let's remember which are the strong acids Is Sulphuric in your syllabus Hydrochloric Nitric Acid Are Strong why is it strong because there is a lot of h+ The more h+ it gives, the more What is the big acid that gives more concentration of h+ aquas ion sulfuric Acid Hydrochloric Acid Nitric Acid Just remember which are the weak acids Acetic acid must be remembered from your syllabus And How are these two carbonium acids which are strong then weak hclo3 h2so 4 which are weak acetic and carbonium h+ ises give next What are my strong bases? Strong Base became strong, after this magnesium and Calcium is slightly weaker than this calcium hydroxide magnesium You can also call it hydroxide Ammonium hydroxide is weak, remember It is important to keep it because lace Concentration oh2 out of the two hydrochloric acid and Acetic Acid Which One is Considered as strong acid and why son out of hydrochloric and out of acetic why is hydrochloric strong Because it gives more concentration of h+ aquas ice in water or aquas solution Give the name molecular formula of one more Strong Acid Another Strong Acid I have told hydrochloric I have told sulphuric There is two nitric, tell me now the next thing The topic is PA, it tells what is PA how much acidic a solution is or how much basic it is in numbers It defines PA means power off Hydrogen Potence Potence means Whose power is the power of hydrogen now you How will you remember this, son? What should I remember? The first thing is Majors H+ Aqua Eyes What does concentration in a solution mean? How much in a solution the more the h psi ion the son the more the h psi ion The lower the p, the greater the h, the greater the p The more the ions the lesser the acid pitch, therefore Look whose Peach Zero is very acidic Peach ji means very less peach h very much Very acidic Rhes and P14 means very Basic 14 is last, right at the end of the scale So PA is too much which means h+ is less If acid is less then it is very basic, now remember this You will also remember to take it in such a way that it is less than seven What happens in acidic water with a pH of seven Equal is called neutral and seven is called If we talk about base in excess then pH of something If it is less than seven then the acid is more than seven You can remember base and neutral on seven like this You must remember that the more acidic The more h+ and the less p ok let's see the question brother CBC 202122 Term One Select from the following the The statement which is true for bases is bases are Bitter is correct it turns blue litmus not red This acid turns litmus red. does that go wrong bases have a pH less not den sane brother bases pH from seven More acid is less than seven and neutral is seven Bases are abstract and change red limes to blue bases are essence, aren't they bitter All these three also went wrong Statements Gone Wrong Bases Turn Pink when a drop of phenol is added to them phenol labor try popcorn p p c pop Corn Remember Popcorn Phenol Pink Colorless What was our base earlier, so in phenol base pink is right bases turn pink na phenol erate Clear Next Beta CBEC 202122 Term Now here are some samples for you You have to tell the decreasing order of h+ ions Have you given the pH value? Son, you have given the pH value of some samples Now you have to tell the decreasing order of h+ Friend, I have given you PA and I want to tell you do one thing Let us first prepare the pH order. The order of pH makes the highest pH Whose son is it? It belongs to the 3 year old, right? 3.7 Which has the highest pH? 3, followed by Whose next is this, the one with four Whose PH will come next, the first one Whose last is the least? Now the son of two P and H+ are just the opposite - the more P, the more less h+ then just reverse it 3 e < 4 e < 1 I take 2 whose is this h+ h+ and pi Isn't its pH inversely proportional? was the highest then its h+ became the lowest Clearly see now, this will be an order of h+ The maximum is two, then one, then 4, 3, this is it 2 1 4 3 You will ask many such questions Good, moving ahead, now something came up Universal Indicator Look Now What did you read about the indicators? litmus read phenol read popcorn phenol Read Tri Turmeric Read Meyer Methyl Orange read then all factory indicators Read, all these indicators were telling only this Whether something is an acid or a base is universal The indicator tells you that something is How much is it acidic or how much It is basic, give me some idea about pH lets give a little bit okay so Substances which detect nature of chemical Age Acid and Base and Also Major Strength Of it one will also tell whether it is acid or Base and strength also example pH paper pH paper son, suppose it is the pH of something comes three or comes one pH is very low one That means too much h+ ice means it is very acidic so not acidic very acidic so what do you It is becoming known that nature is also becoming known that Acidic is also major the strength of it So it measures two things: nature and Remember that strength gives you nature and Strength of any solution now there is some Things you need to remember to look into Does pH paper have any color? whatever it is it has a colour what is the colour son The more you go towards red, the more Acid red means danger danger means acid and The further you go toward blue, the This is basic, now how to remember this Remember, you must have heard about VIBGYOR, right? spectrum vibgyor vibgyor reverse Write it down, the more violet the more basic The more orange to red the more acidic Guess what will be the term between Vibgyor vi b ro it removed the middle came g Green then green means neutral clear The more violet color, the more Basic and as much as you are coming this side of red On one side Vibgyor is as acidic as Vibgyor on the other side and who is in the middle vibe removed roy removed diya ji green so green neutral now in this You have to remember some things like stomach acid gastric acid number one gastric Acid number one Very acidic gastric juice about 1.2 what is a number red or the second lemon in the middle of the orange how many lemons there are two lemons in the house number two lemon juice very Acidic 2.2 Beta as acidic as orange and less so on the red side pH is fine lemon juice then you need water newt So where is neutral, vib gear on green Neutral one more thing is milk of Magnesia Magnesium Hydroxide Its The pH is 10 and it is blue in colour you will have to remember PA 10 and blue color and lastly sodium hydroxide very Strong base is very strong then 14 more 14 means it is completely clear towards the violet vibe So you have to remember these things about acid base let's ask the question, we will remember it It is very simple, come revise it with me once The more h+ the less acidic it is The lower the pH the more is the color red It is clear, the more on this side The pH is more basic and the color moves towards violet brother let's see let's see the question CBSE 2023 exam date information Regarding pH and the Nature of Four Different solution watch of the option in the table is Which one is correct? You can do it yourself yes you are fine what did you give here pH value is given, colour is given, nature is given Of solution see what they are saying about lemon juice are you basically wrong in saying lemon juice it is acidic where were two lemons Milk of magnesia has a basic pH 10 is blue color blue color 10 basic correct gastric juice not number one but number six Diya is pure water is green, yellow diya If it is wrong then it becomes correct Next CBSE 2030 to Solution A A Give Red and Blue Color Respectively With This Indicator A Koun Son, it's giving a red color which is towards red That acid is going away, so it's yours acid and a gives blue n which color give Raha Hai Blue Vibe Gar Violet Indigo Blue Green Low Range Red Red Kinza Peaches Low Acid towards and wa indigo blue basic so son a what happened your basic is done what are you Went acid present in solution will give hydrogen Tell me the ion concentration of this Which has higher hydrogen ion concentration it will be in m justify your answer because m is acidic if both m and n solutions are mixed and the resultant mixture is Tested with a universal indicator it turns green m a and n mixed acid And what will be the base, what kind of salt and water The solution is that it turns green, so son, this is what It turns green, which means it is now neutral must be green color is neutral right what is it what will be the nature of the salt form son Nature salt's neutral salt will be fine Why is it neutral because it is green in colour Let's move ahead now importance of pH Some examples in everyday life Let's remember the human body from NCERT The pH of water is between 7 to 7.8 Right around the waterer our The pH of blood is also the same. The pH of our blood is also the same in the human body If the pH of rain water is 7 to 7.8 If the value goes below 5.6 then you will have to remember it What happens son, acid rain occurs If the pH of rain water is less than 1.6 It is less, which means a lot of acid is coming out now Suppose if the water goes into the river then the fish becomes still they will not be able to stay, it will be difficult for them to stay because just like our human body The pH is 7 to 7.8, so is theirs There is a certain pH range beyond which it is not If you stay alive then this tells you that you are a PH patient What are the applications of acid rain? I went to the pH of the river, what would be the acidity? then the pH of aqua life will go down Survival is difficult next remember stomach Which acid is produced? sa aqua solution sorry ac gas nahi h sa Why does X produce acid stomach h s helps in digestion of food now many times It happens that you have acidity, what happened son, go out I went and ate samosas, ate puris and kept eating a lot of them keep eating And then what happens if there is acidity? My son is unable to digest so much food I want to know how to digest my stomach what is it, put it like this, everyone will choke the stomach how do you feel the food has arrived what is the work sir please digest the food sir I have to digest it, yes, but do it slowly I eat it, take acid and it starts pouring acid Now when you eat too much then digestion It doesn't happen, the stomach says I will melt it and take it. Take it during acidity condition if it gets worse Indigestion makes the stomach produce too much acid you should not eat too much it causes pain And irritation now son if it becomes very acidic If yes then how to correct it, what is its solution base base which milk of magnesium Magnesium Hydroxide PP Anta Acid Magnesium Hydroxide Mild Base VO you don't drink eno eno, right? work has started 6 Which antacid do you use in seconds Anta acid means who is against acid magnesium hydroxide antacid what is it Neutralizes excess of acids which There is access of acid in it and magnesium you will get hydroxide hclo2 and water chain is done brother pH is off If the mouth is less than 5.5 then son, his teeth will get rotten If the pH of the teeth is less than 55 then Son, your teeth are gone. Yes son, why would your teeth be gone? You eat chocolate etc. and don't brush your teeth You are sitting inside, bacteria chocolate came what will it do, it will make the acid of chocolate Food is stuck in your teeth, sir, you fell asleep at night what does it matter to me which date is the next day go to pay I have to go, you don't know about it If I don't want to go then I should brush my teeth, yes I will sleep brother Eating chocolate at night like a child What are you eating in the morning, what is stuck in your teeth It happened brother, my teeth started breaking and getting damaged why start because bacteria made chocolate what did you make of it acid made of due to Sugar and food degradation, now what about this brother What is the solution for this? Use toothpaste every day. Work on alternate days and do it for three days in two days I do it once a week Manjan GB works but GB does nothing The toothpaste is absolutely dirty, so brother the toothpaste base What is in base toothpaste What is there in base colgate etc. there is a base so what does he do it neutralises the acid Next son, the sting of the honey bee Honey bee is there, right? What is in a bee's sting? bees contain formic acid If the blood is burnt then it is fine formic acid What is the method to apply a mild base low like baking soda baking soda nahco3 I will teach you further, don't worry now if What to do if a bee kills you like this? Baking Even if you buy soda from the shop and apply lime on it, it will work It will become lime water, it will be lime water Take the paan which is eaten with paan do you eat Should we eat sweet paan, yes Nettle Sting Beta Nettle What is a Nettle? The plant has stinging hair so this nettle plant what is it methane Acid is present in some plants like Did you ever play cricket in your childhood? The ball would not go to the Bagla plot Or would you go to the forest again to get a thorn I wondered what it was, son, it was made of nettle There used to be a plant that had a thin layer inside its leaf The thin sting used to pour methane acid like this I hurt you inside, so what, brother? Where nature hurts right next to you He gives a solution like this, there is no such thing in life If everybody says that NCERT book is a lie then They say that the brother has a dock next to him there is a plant which is basic then I took its leaf and rubbed it and it got cured It is like a tribal, what is the remedy Rubbing area with dog can cause nettle sting then methane acid is used to correct it Method Rubbing Area With Dog Plant Dog Where Nettles Grow Plants That Grow Beside Nettles It is right next to the nettle, isn't it? Nature Provides What does nature give as neutralization No one ever neutralizes you The prisoner looked very beautiful, I liked it very much You fell in love, you went to her and told her everything and he pushed it back you pushed it forward bola i have a very big crush on you i Like you he said and something else than this Bad and what reply then you came crying So who came to explain it to you, his friend? What you didn't like came to you To save money, the dog plant is right next to it So wherever there is trouble, my son is there Don't take these solutions too seriously Nobody is coming to make you understand anyway Look at my face, my pH of salts is also bad what can we do with pH of salts now How to find the pH of salts, acid, base I understood that strong acid is very less pH of red solution base is around zero P around 14 means the same seven over 14 If it goes away then violet violet color is absolutely How to find out the pH of salt What is salt made of Acid is made from base Acid is made from base So the acid base will tell if it is strong Acid and Strong Base Meet Strong Acid Strong base then neutral salt pH Gone are the strong acids and strong bases neutral strong acid strong base Neutral, now whatever comes after this is strong The salt will be as weak as the acid will be strong Base salt Basic PA greater than seven Clear Strong Acid Weak Base Acid If it is strong then the salt should be acidic and not base It is weak, the stronger the salt the better strong to acidic drink 7 hey sir forget Brother take this strong acid quickly Quickly remember the bar, brother Strong acid h2so hclo3 weak acid ch3cooh and h2co organic this must be remembered strong hc2 so4 hno3 week ch3coh and h2co Strong Base n How did naclo3 become this strong acid what is strong base clear brother I have to do naclo3 let's do that kno3 Where would the potassium come from, son? hydroxide and nitric acid what is it is k strong base nitric acid strong Check the acid Nitric acid Strong acid hco3 How is Carbonium Base Acid a Weak Acid? carbonyl ide is the bol Babu, seeing the weak acid, you also taught me brother carbonyls is weak weak h2 co3 so son strong base weak acid tell me what will happen How will the solution salt become basic P what will happen anyone bigger than seven can do it is there caso4 in this where did the calcium come from where did the hydroxide so4 come from h2s speak bhai strong acid strong base Taking the neutral solution on your own You have to do the rest of your homework yourself, come on brother Let's see the question CBSE 202122 term One N Aque Solution of Salt Sols N Orange Red Color One A Drop Off Universal Indicator is added to its salty son Orange red vi gyer means what type of salt is it Orange red of beta aqueous solution salt So son how will the salt be acid will it be yes or no orange red is very acidic so son what is the acid salt Tell me if strong acid will be formed from weak base What will strong acid and strong base be made of? Weak acid works with strong acid and weak base Brother let's move on to the next question yes the question is CBSE has come in 2024 An equal solution of salt turns blue Litmus to Red is turning blue litmus red What kind of salt is this brother, it is an acidic salt Salt could be obtained by the reaction of It is acid salt, from where did the strong S come add weak base acid should be strong hno3 Strong Acid naclo3 term one will run automatically homework ok brother this is your homework Let's move on, next son, this is some list It is important to remember that naturally occurring arginine acid The condition gets worse sir who remembers me so much How do I remember it so let me do it quickly how do you remember Isn't it orange which acid is present in vinegar Let's go and tell stories brother, let's start do one two three here we go vinegar means I took the bottle of vinegar and drank it. After this, he will act in Babu Musaye drama Ami Manjuli's acting will make you crazy Acted after drinking vinegar Acted after drinking vinegar If you start doing this then drink vinegar Acting Acting Means Acetic Acid Vinegar Meaning he acted after drinking vinegar Acetic Acid Orange Peels I didn't peel the orange, I peeled it, the whole city was inside What's inside the City of Orange City Orange peeled inside city came out orange peeled inside city orange peel inside city city meaning Citric Acid Clear tarin son what is tarin tamarind pata you probably will Tamnus falls, we are the ones who eat it no tamarind tied the tamarind with wire imagine I tied the tamarind with a wire in my mind Lots of tamarind tartaric acid tamarind Tartaric acid from tomato tomato home I have kept tomatoes, I don't feel like eating them Who will we feed when we go out and feed the cow or the bull Who fed the tomato to the Ox? Ox Who was fed oxalic acid tomato Ox ate oxalic aid in brain Tomato took the ox and brought the next essence Milk essence means milk, curd means curd. Don't you feel like eating spoiled curd? we will take it and throw it in the river Where did you throw it, in the lake, isn't it? I threw it in the lake means lactic acid lake means Lactic Lemon Beta Lemon Recipe What is a sour orange like? What is a sour lemon like? peeled the apple and also peeled the orange both Like big orange and small lemon both are sour did the sour lemon have a green slit inside it City came out, lemon peel came out, city inside Citric acid turns out to be the next ant sting so son ant is one we have an ant are you hungry what are you eating fenugreek What is Paratha Ant eating? Methi Paratha And brother, give me a small methi paratha What is Methane Acid and Sting? I ate fenugreek paratha, I felt a nettle sting Son, take out the net from the nettle sting, net one Net is our nettle sting I have one There is a tree where the ball went, do you remember it went I had scored a goal, yes, forget it, it was in the net, son Is the methi paratha stuck in the net too? Ant also ate the methi paratha which is stuck Fenugreek is also stuck in the net Paratha methane acid remembered the whole yes no Tell me brother, did you remember, come on brother, revise quickly Let's start with vinegar PK Acting of Acetic Acid Orange Citric acid extracted from peeled city tamarind Tartaric acid tied with wire is not tomato The cow was fed oxalic acid Sar milk means curd curd has gone bad What did you do? You threw lactic acid in the lake. lemon lemon sour orange sour orange lemon I peeled the orange and found a city inside What do citric acid ants sting insects What did Ant ask for? Methi ka Paratha What is caught in the Cheated Nettle Sting Net Methi ka Paratha is methane acid clear so this this is how you will remember it brother come on watch Let's take the question CBSE 2023 ACID Product in Tomato Who ate the tomato Ox finished oxalic acid brother cbsc 2021-22 Term One, you can do it yourself friend You will do your homework, if you remember it settle it yourself i have to mix it brother orange What came out inside the peel? City Oxalate Acid What went wrong? Where did you throw the milk and curd? The lactic acid in tha lake is right ant What did Sting Ant eat? Methi Paratha that's right tarin means tamarind tamarind what is it tied to If acetic acid is wrong with wire then what is right if it is 2A3 then check 2th is correct yes common Salt is baking soda read is washing soda You have to study now, you will remember everything, don't worry Let's start first, son. We will read the formation of AO sodium Hydroxide Sodium hydroxide is caustic soda is also called soda wherever Come on soda means sodium soda means sodium How is caustic soda made, son? This chlorine What does chlor alkali do with alkali process? Are I put the aqua then braille says plus h2o what did you do, gave it electric current We say electrolysis is electric Current means electro-license, what all Chlorine gas will be released, Hydrogen will be released The gas will come out and na2 where is at anode hydrogen where is at cathode How to remember this so Chlor-Alkali is a thief who steals things Who has come to do this? By whose hand did Khali get caught? Sahib's Khali Sir, I will catch you and Khali Sir He caught the thief and told him to do this here now but drink salt water should we drink salt water first The thief was made to drink salt water and the salt water After feeding him, he was given electric shocks Imagine who caught the thief, Khali sahab caught the thief and drank salt water after that he got an electric shock electric shock The thief fell unconscious and was thrown into a box I closed it and parceled it out Come on thief, get out where do you go to China brother, China things don't go right anyway, you are the same Go then who did Khali sahab catch the thief what happened chlor Alkali what is given salt water salt meaning salt e water h2 a p h2 salt water drink what did the electric shock do electric tax The thief became unconscious due to power cut, what made him unconscious closed parcel cell positive p a anode cell chlorine so what is chlorine being formed at the anode where did the gas go China Sea cathode h hydrogen AO then where is hydrogen at the cathode Khali Saheb Chor Chlor Alkali Salt Water Salt and water Look at naclo3, what happened on positive Parcel positive anode Chlorine positive anode Chlorine and China Sea Hydrogen will be formed at the cathode and A will be formed here There are some usages that you need to remember Remember if the products contain chlorine then thrown into the swimming pool A little something to clean the swimming pool Imagine yourself in a swimming pool Swimming pool cleaned by chlorine added Chlorinated water gets cleaned simultaneously In the swimming pool you think that there are many If you are putting insecticide then it will become pesty I am putting sides, remember this one Chlorine sanitizes swimming pools and What is the pesticide used in swimming pool? Where is hydrogen used as fuel? Hydrogen has become a fuel, do you know a lot If the fuel is good then what should you fill the fuel in, son? The dog came near the car and gave birth to a baby I did it while saying that the truth is on Shamri The dog came near and gave birth to a baby and the baby What is ammonia What are the types of ammonia If there is fertilizer then remember hydrogen fuel Where will the fuel remain in the car Who comes near the car, the doggy does a baby ammonia in the baby which is fertilizer okay Trees got nao2 from fertilizer n so friend how to remember this nala hot n There is coal, there is a drain in which bubbles come out There is a hot drain and what is in it there is soap in it there is detergent in it there are lots of papers lying there If you have bundles then make soap and detergent It is used in There is soap bar and powder Nirma Washing Powder To Soap And Detergent If it is done and the papers are clear then Remember the chlorine to clean swimming pools add chlorine to it and You put pesticide in it, right? Hydrogen fuel to kill insects and spiders Put fuel in the car, dog is near the car I came and peeed, there is ammonia in my pee And na8 hot hydroxide in hot drain Bubbles are coming out, what have you read in them soap and detergent and paper making These are used for CBSE 2020 list Important Products of Chlor Alkali What products come out of the process Parcel and China Chlorine on Positive Anode Hydrogen and Na Sodium at China Cathode Hydroxide has one important use each one is useful so i reminded you next Son bleaching powder now its chemical Sometimes I don't remember the formula and that's the problem If it happens then it looks like beach with bleaching powder I am feeling it, look it looks like bleaching powder it's like something beachy they're saying bleaching The middle is just a middle in which the powder is lying Now who's on top of the middle Two on top of the middle Clown is two jokers on an ox We're sitting and the ox is pulling a car So what is there above the middle here, son? It is written look what is there to clown remember pulling a car on an ox What does it mean to keep bleaching powder in between? There are two clowns sitting on the ox driving the car Two clowns are pulling me, I mean son two chlorine ox means o car means calcium caocl2 became car means calcium oxide oxygen two clown cl2 caocl2 bleaching powder will always be good to remember next what How is Slag Lime Made? Slag Lime put chlorine in coh2 wise chlorine in put it in the container what will be formed caocl2 and what will be formed nickel the water will go away ok how do you remember I will keep this and remember it at that time Bleaching powder means what was there on the beach There were two clowns sitting on oxen and pulling a car There, a snake was licking a lemon Snake Lime Snake Lime was licking the slag line so how It is made exactly there, exactly on the beach, just on the beach where the clown was what did the clown see Snake licking lemon no claw saw it If the snake is licking lemon then slug lime I added chlorine to it, what became of bleaching Powder and water are gone son its usage You have to remember this before bleaching It will bleach the clothes right? Removes or restores color I will remember both things, won't I remember them Beach Bleaching Means Beach Above Beach If you are washing clothes then bleaching on clothes Bleaching cotton linen wash is done, right? clothes cotton clothes linen clothes or wash clothes on the beach and after washing the cloth take it in the glass Squeeze and all the germs inside the glass will die It feels so weird, but this is what I remember I will keep it in the middle and wash my clothes in the middle beaching powder bleaching powder cloth washed Means bleaching action on clothes cotton linen then after washing the clothes go to the glass All the gems died in a big glass Drinking Water Free From Gems and One More thing is oxidant remember okay so Ni Choda Make Drinking Water in Glass Free from james now see what is the question CBSE 2023 The INDUST Process Use For Manufacture of Caustic Soda Caustic Soda So how do you manufacture this? yes we are chlor alkali and not chor khali Evolve electrolysis of an x solution of compound aces which we people Khali sahab does electrolysis on the thief what did you give him to drink after catching him? Salt water, salt Meaning two gases wa and jade are libre to bhaisaab Then the thief was given electric shock after being made to drink water Then the positive anode was sealed in the parcel Chlorine and cathode hydrogen were sent to China Sodium hydroxide shows two gases is chlorine and hydrogen va and j va is Libre at Cathode So what is China on Cathode cathode hydrogen so what happened hydrogen is lead cathode cathode is china cathode hydrogen and jud which is positive anode chlorine What if the parcel became rooted? Chlorine became rooted. Weil brazed at anode on treatment with Dry Slag Lime Forms Compound B Now what is the root saying which is anode librate What is the problem with chlorine on treatment Dry Slaked Lime Slaked Lime Means Snake Lime Snake Lime Dude beach co hole twa what is visible in the beach what were the two clowns I was sitting on an ox and the ox was pulling the car car calcium one ox two cocl2 okay and What comes out son h2o clear cbc 2020 during electrolysis of brile Now next is baking soda baking soda what is nahco3 how to remember Baking Soda Looks Like Baking Goat Have you seen a soda can? People drink soda. The goat is drinking soda, remember baking soda Meaning the goat is drinking soda the goat is wearing glasses the goat drank soda and the soda is doing good When a goat or any animal is happy it is chill if it happens then what is he scared of? I feel that nobody will come with the car Who has come with this brother, brother has come on the bonnet of the car How did you come sitting on the car bonnet brother? How did the goat come to this condition after sitting on the car bonnet goat was drinking bad soda baking soda Soda goat soda who came brother on Carbonite Brother On Carbonite Carbonite Car so bicarbonate of soda means sodium sodium Bicarbonate Now remember baking soda, you will never forget it Now who was drinking baking soda goat soda from Dari bhai on carbonate bicarbonate sodium What is the bicarbonate reaction Briem naclo4 c and sodium hydrogen or what is bicarbonate called baking Soda, you have to remember this reaction naclo3 nh3 nh4cl and nahco3 Well what are the usages so look now the goat so remember goat soda what did goat soda do What will a person do after drinking soda? Now I want to eat crispy crispy Who will I eat pakodas and dumplings with in curd After mixing it like this, what do I do with the curd I will heat it up in the cooker and when I am heating the cooker and it might catch fire If there is a chance then bring a fire extinguisher as well I will keep this story in my mind and remember it can you drink baking soda goat soda she was planning to eat pakora after drinking soda Crispy crispy and cooker kept next to it in which curd is kept and so that it does not catch fire In case of a fire accident, remember these things first. Will you go for making tasty crispy Pakora is good, I had kept cooker for faster What is cooking good and soda acid fire Delay was being eaten with extinguisher and curd Curd of milk and what else do you remember son this Sometimes they are also used in antacids It doesn't happen when the tree lights up at night Mummy says drink soda water then see When the goat ate all this, it ate so well I ate this pakora and curd and my stomach got upset what did you do in the last time you drank soda water This is how you can remember it or memorize it Take whichever of the two you like, whatever the story is Come on, what's next, son? Baking How is baking powder made, son? what do we do with baking powder Baking powder must contain baking soda It must be baking soda, which means it is goat soda and the goat soda pirth is tied to it with wire given tartaric acid then what is baking soda hai sorry what is baking powder baking baking powder in beta baking powder soda is baking soda goat soda and if you tie it with a wire then it will Tartaric acid Baking soda Baking soda what is goat soda who is coming bi sodium bicarbonate carbonate now son If carbonate reacts with acid then What comes out is carbon dioxide gas Carbonate or bicarbonate is what comes out What does carbon dioxide gas do, son? This is how it makes bread puff up or coke turn into rice Does it do that or does it make it soft There is bread, right, if it puffs up like this, then what? it fills with carbon dioxide How to fill sodium bicarbonate Look, you will remember what you mix tartaric with baking soda what soda was the goat drinking bicarbonate sodium bicarbonate now Baking powder does contain baking soda That means goat soda is now ready i.e. sodium bicarbonate got and the goat which we tartaric acid Look at the carbon that came out, whenever any carbonate Carbon dioxide reacts with acid When this gets filled up, things become soft. The question of 2023 is state the difference in Chemical Composition Between Baking Soda Goat soda bicarbonate sodium bicarbonate And baking powder, add goat soda to it. What happened to sodium when it was tied Bicarbonate Plus Tartaric Acid Next What is washing soda son, now do you remember it? Soda means sodium washing means washing gonna do it sodium carbonate deca hydrate If you want something then I will make it for you I tried to make a little bit here Nirma bhai what is washing soda washing powder manufacturer manufacturer is manufacturer and what have I done here atom and who is this Hardy Sandhu Parmanu And Hardy, what did we do to Nirma? Hardy Sandhu, what did we do to brother Nirma Hardy Sandhu washed away the atom from Nirma You must have seen that you could never imagine isn't it Hardy Sindhu I love you anyways He washed the atom with Nirma who said hardy sandhu atom then hardy Permanent to permanent hardness of water Remember the washing soda formula it will cost na2 co3. 102 You can make something Can you tell me how sodium is formed son? heat the bicarbonate sodium carbonate Sodium will release water and carbon dioxide React the carbonate with water na2 co3 10 h2o glass soap peptidry and what else Hardy Sandhu created Nirma Powder i.e. Washing Powder Maker Washing Soda Atomizer Permanent Hardness Nuclear Hardy Permanent hardness look what is the question the name of the Salt use to remove permanent hardness of Who takes out the water, son? Washing powder Nirma Hardy took over i.e. washing There is soda or washing soda in it, look at this sodium carbonate deca hydrate deca Why do we call it hydrate, son? People Sodium Carbonate Deca Hydrate because 10 is h2o then deca hydrate is 10 h2o and what is cbc 2020 how is washing Shada prepared from sodium carbonate How to prepare it from sodium carbonate na2 co3 so son add + 10 h2o to it what will become washing soda na2 co3 10h 2o and what is the state the type of this salt so son what kind of salt is this na2 co3 102 where did naco3 come from h2co so came from naco3 where did h2co 3 weak acid come from What kind of salt is this, son? Is this basic salt? gaya nen the type of hardness of water which can be removed by its permanent hardness don't you remember the atom water of What is crystallization, son? A molecule of water is equivalent to one unit of salt. water of clings to him crystallization fix number of water Molecules Present in One Formula Unit Of salt, there are a few things you need to remember A crystal of copper sulphate CuSO4 h2o then washing soda na2 co3 10 h2o Sodium Carbonate Deca Hydrate Spoiled Then gypsum calcium sulphate. 2H 2O and ferrous sulphate crystals feso4 7h so this is for you Remember five things, remember these four things It must be copper sulphate. 5h 2o na2 co3 10h 2o feso4 7h 2o caso4 2h it is called gypsum Now how will we remember gypsum from gypsum the tongue will remember the gypsum tongue the tongue will remember So what did we do with the Jeep? We made a Jeep in each plate. licking it and there is a cat in that plate and licking two water glasses gypsum jeep plate There is a cat on the plate and two glasses of water CAT Calcium Plate Sulphate Water Glass 22o Calcium sulphate water glass clear remember tongue You are licking the plate from the plate meaning Sulphate Cat Means Calcium and two glasses of water 22 caso4 22o gypsum Tell me what is the question of CBSE 2024 Out of these compounds maximum number of water is Of crystallization types are the most There will be more water of crystallization varieties son maximum of na2 co3 102 feso4 near 72o cs4 near 5 and gypsum near 2 then the answer will be na2 co3 plaster off Plaster of Paris POP at Home If it is pope then plaster is done Paris Pope If you can remember the Pope, son What is plaster of paris which is made from gypsum There was no cat in which he licked the plate with his tongue and two water bottle plate means sulphate cat means calcium two water bottle h2 h2o caso4 22 gypsum is heated to 373 Kelvin i.e. Heat it to 100°C What will it take to drink one and a half glasses of water take out 3/2 and a half glass of water The remaining half of the water in the glass is gypsum caso4 1/2 h2o sorry that is plaster of baris then how will you remember the one who is pope what did you do with the gypsum in the plate There were glasses, out of which one and a half glasses of water and the Pope kept the remaining plates for himself If you took it then what happened caso4 1/2 h2o Cat in plate licked plate with gypsum tongue and two water bottles c cat means c plate mean sulphate caso4 two glasses of water o 2 h2o Pope removed one and half glass of water from it diya tell me how much 1/2 h2o cs4 1/2 h2o how much It is heated to 373 Kelvin i.e. 100 degrees what is the use of plaster of paris son What is the use of POP? What are toys? To make the surface smooth and material of It takes time to make decorations when Your hand is broken, paint the house first It gives wetness, after some time it dries completely hardens because the plaster of When Paris is mixed with water it turns back into gypsum This is what creates the opposite reaction, isn't it? Add this CBSE 2020 will go tomorrow You all will go to chemical formula from plaster of paris then son plaster of What did the Paris Pope do with the Jeep and a half glass removed water of c4 1/2 h2o a compound x which is prepared from gypsum Which compound would have been made from gypsum POP will identify and write its chemical formula so cs4 1/2 h2o so here The whole chapter ends while studying all the very best
