We are about to go live on YouTube. Once Look quickly everybody yes I pinned the link. see link above The link is pinned in the description. Ok? It has gone live on YouTube. I reach I am taking classes on YouTube. Everybody come on Quickly. The link is pinned above on YouTube. Is No? Click on the link and go to YouTube I am closing this class from here. Now Class continue class on YouTube. Ok? Ok everyone understood. Show me the motor. I closed I am taking class. Understand? Show me the motor quickly. Yes. Let us go Correct. A clear audio video is playing perfect check it once Tell me in the comment, quick audio video Perfect Yes The weather is as per the thoughts There is a namaskar inside a human being, Jai Bharat I welcome you to Ajay Mishra On this wonderful channel where today we are talking about Phoenix are going to take the first class of 3.0 and this This is a class of solutions. So quickly this session Share it with more and more people Please deliver it to me. Everybody join in. 2 hours This class is going to be really great, isn't it? These will be totally conceptual things Strong-strong. Everything is going perfect? Show me your thumb. Moved ahead. Will be started. Is the voice slow or is the voice coming out perfect? How many people are experiencing low voice? Double voice. ok low voice Hello Hello is there a voice issue it is great yes don't keep the plus class open Brother, please stop it, yes, classes in two places If you open it it will echo. Ok? Balance How many have perfect voice? Once Show it to me quickly. It's fine now. It's fine now. Check it. then because the session has started Will go. I won't do it in between. once again Check it. If double is coming then once somewhere else If you have a session open, close it and open it somewhere else. brother there is session It's true that my voice is echoing There is a little tinkling sound, it must be happening that's why That is not the tension, the rest can be heard You will get proper Isn't that the echo quality of my voice? If it is there then there is no problem. Let's get started Are. So if the session sounds worth starting If the sound is so loud then everybody thumbs up once Please show me. Show me your thumb. quickly Let's get started. Isn't it? Let's get started. So brother, today we are going to Going to Solution Lecture One. I told you about the voice, if there is any issue If it is then I will get it solved in a little while In. Ok? I told you brother. Let go so solution lecture one The first thing when you read the solution chapter Let's read it, right? So there are three kinds of things Comes to you. three types of Mixtures come to your mind. First true solution, second colloidal solution and Third suspension. So let's talk about all three first Start the discussion. The first thing that you What needs to be done is the true solution. Second you have to talk about colloidal solutions. And the third thing you need to talk about is suspension. okay brother? So let's discuss all three We do. See if you talk about the true solution Are. Let's say you took a container. Fill the container with water brother. What should I mix in the water? NaCl Mix NaCl in equal quantity of water and now everything is ready It is going perfect. Take it easy for now and proceed with the session Can be increased. Tell me everything is going perfect It has been in my opinion. I have asked for low voice. Some? If there is an issue then it will be solved now. just so much So that means you can hear it. You have a voice, right? That means the voice is okay Can you hear it? Ok. So try it And also to listen. And Gradually everything will become perfect. get it done right now I will give. There is some other problem, solve that too. Look what I have told you inside the solution spoke? There are three types of mixtures. Is No? What are these three types? Mixtures. So when you compare these three types of mixtures Let's talk about classification first Take it. What is this? three types of Mixtures. One mixture is called true solution. The other one is called colloidal solution. What do you say to the third one? Suspension. What is the difference between these three, brother? you water Take. Add NaCl to the water. so tell What will happen to NaCl inside water? Dive Will it happen? then it will form inside the water Na+Cl- What will you say to this? all these aqueous ions will be converted into. equals here Whatever term you use, what will you say? NaCl It dissolved in water. what will you say? NaCl dissolved in water. Equal. Here But what is going to be made, will be the true solution Going to do. There are two special things in this. Number one it would be homogenous. Isn't it? And number two would be this uniform. What does uniform mean, brother? Isn't it? does he wear a uniform? of uniform It means the same everywhere. of uniform What does it mean? Same everywhere. equal denominator The space distribution will be the same. From Somewhere Also take out a little bit of it which is similar You will get the distribution. whether from above Take it out, either from the bottom or from the corner Take it out from somewhere, take it out, the uniform There will be distribution. Ok? Homogeneous means single fuzz. Somebody ask what is here Is the fuzz going on? Liquid Fuzz is blowing and You are getting aqueous ions in this. Equal What do we guys call this? True Solution. Come to second number. Second Number What will you do in? you take water again And what did you mix in the water this time, brother? Oil. What to mix in the water? Oil. Tell What will happen if you mix oil in water? will be? does oil dissolve in water Or does it disperse? So brother inside the water Whatever oil is there will float on the top. So look Like water is below so here is a layer of oil It will become like this. Correct? So tell me who will stay downstairs? Water or Who will stay down? H2O and who's up here will it remain? Oil. So tell me what term do you use? will you do it? What happened to the oil inside the water? Has it been dispersed? so here What technical words will you use? To be discharged. Isn't it? It has been dispersed. So oil does not dissolve in water. Oil Disperses in water. here which Tell me what you are going to get Going to do? Homogeneous is going to meet or Heterogeneous about to meet? so you They will say heterogeneous. Heterogeneous. Are you getting two different faces? Oil is not mixing with water. Oil I am not mixing. The different faces Both of them are sitting with it. The third thing that What is important is non-uniformity. This Bar matter is non uniform brother. Tell me non Why is there a uniform? because everywhere there is a There isn't any distribution like that. what two Do you understand things? The session also Share it as much as possible. and right away You will spend your two hours in an energetic way Strong case. So this is all your work. Keep sharing the session, hit like if You understand it and it's fun Read it. okay brother? Ok? Let's go to the next one. Number three But when you discuss, tell me this time When we talk about suspension, then water We will take clay and mix it in water. then respect Here, I took some water and sank it inside the water Mixed up the clay. So when you mix clay with water So tell me brother what will happen? Clay in water What will happen if you mix it? Is there clay in the water will it dissolve or disperse or go down will you sit down? Everyone type this quickly. What Will it happen brother? The clay will dissolve in the water, will it disperse or go down and sit Will you go? So tell me when you mix clay with water So does he go down and sit down? What? And if he goes down and sits down What will you tell him? it comes down here Look, he sat like this. Who is this down there, brother? This is Clay. Who is up there? This is water. what term is this will you use it? what term will you use here Pay? Suspension. what happened here? Suspend Done. Ok? So, you would say clay is inside the water He got suspended. Ok? The number two thing is that you Which is what is available here, right? which you It is available here, how is it? Heterogeneous or Homogeneous? this time too Heterogeneous. Heterogeneous And how is the non-uniform now? Non Uniform Look, it's not the same everywhere, below The distribution is different from the above distribution It is different, if you understand the difference between the three Tell me which of the three is homogenous is gonna be the homogenous type of the three which one is first, second, third, tell me brother which one one is homogenous the first one the second one Which is the third homogenous one? Tell us the first one in this chapter which one is it? Do you want to study? the first one Is it clear? I'm going to start with the slide numbering here I keep doing it. Isn't it? So brother absolutely We work systematically. Like Plus Pay Let's go, we have to go here as well. Is No? Let's go inside now. Out of it Tell us which reading to do in this chapter Is? Which one should you not read? Tell me which colloidal substance is Where do we read that there is a solution? Surface In chemistry. So this is what we get in this chapter I don't want to deal with this. we read this right now in surface chemistry which has now been removed Has gone. Isn't it? He is missing from the scene. There is no need to read the suspension anywhere. Any object goes into water and gets suspended It has been happening. What will you do after studying, brother? Isn't it? So you should not read this also in this chapter. Is. So tell me who in this chapter Want to make a deal? The only and only true solution To. Who wants to deal with? Only True to the solution. Who do we need to read in detail Are you going to? True Solution. Right? When you throw something into the water Three things can happen. number one either he It will be resolved, number two or he will go It will disperse and if nothing happens Then he will be suspended. sit down Will go. Do you understand these three things? Ok? so now we're gonna read true Solution. so the next part from here What starts is the true solution. Now Whatever I say, it will be about whom Tell me will I do it? Now from here, whatever I say Who will I do it about brother? True solution, right? Now all the talk is true It will be about the solution only. That's right. All discussions are about true solution It will be about. Ok? First Statement Come. Statement number one. Statement number one. Now watch when I say the solution term. When What should I say? you understand the solution What does it mean to go? True Solution. And when you get a question somewhere, it is No? You get a question in any exam, The solution is written there. So, Do you understand who he is talking about? True Solution. Again and again he tells you the truth He will not give the solution in writing. clear is there a point? So, now I write the look statement I have been. statement number one everybody Solution Is a mixture. every solution is a mixture But Every Mixture but every mixture is not a solution is not a solution What do you think of the statement? True It seems to be false, tell us in the comments. People of 1.1 are live brother. Isn't it? 1100 people Watching almost live. So quickly to the session Share this with more than 1100 people. Absolute fire We are going to put it in the session this time. Isn't it? Brother, we should find out a little about the market. Share this and like it more Hit it if you find the session intense. I am giving you the exact same content Which I give you in the main class. At once Providing you the same content here Am. every solution is a mixture but every Mixture is not a solution. tell me right is it a statement or a false statement? At once This is a correct statement. Tell me what is he saying? he is telling you that every solution when I type the solution word I am speaking here so tell me whose Am I talking? Am I True Solution am I talking about? yes when i find the solution I am speaking the word. So every solution is a There is a mixture. Then you will mix something It will be done, brother. But by mixing anything Every mixture, by mixing anything you get Solution is not found. Means True Solution not get. Tell me when I already tell you I have already said that speaking a solution means speaking the truth The solution is mine. Ok? So tell me this Are all three a mixture? This is first, Are second, third and all three a mixture? But out of these three, the true solution is Just which one is it? It's the first one right So by mixing anything we got something random True solution is not found by giving but If you got the solution then you mixed something So it must be the correct thing, it is absolutely the correct thing So tell me, do you understand this statement? It comes with a completely correct statement A solution is a mixture, but every A mixture is not a solution Next Let's take the statement, let's take the next statement You got it, keep showing your thumb to everyone If you understand then show me your thumb Ok. Next Statement Statement Number Two Statement number two it is not necessary that the phase of it is not necessary that the f of solution is always liquid it may be I am also telling you brother, I have been careful listen, I also understand, maybe you also understand it may be Solid and gassy also Tell everyone please type the statement How does it feel to be right or wrong? 1.2 Brothers have gone live, the audience is constantly increasing The next statement was made in the presence of a huge crowd of onlookers It is presented before you, tell me everyone is right It is wrong, it is not necessary that The Fuzz of Solution Is Always Liquid It May Be Solids and Gases Also It is correct, it is not important that it is correct. What is he saying to you? brother is saying it is important Not there. Everybody should participate a little In chat right now. Isn't it? Brother it seems that you are a little Are active. It is not necessary that the The fuzz of the solution is the fuzz of the solution. Isn't it? Fuzz of Solution. It is not necessary that he Always be liquid. because when you find the solution When you read a chapter, a thought comes to your mind The image is created. We read Liquid Liquid have been. But this is not necessary. The fuzz of the solution should always be liquid. As such It is not necessary, it is not mandatory. it It can also be solid or gaseous. it may be Solid and it may be gaseous. this is also correct There is a statement. The matter is absolutely true. Now you They will say, give me an example. take an example Brother. You can take the example of solid. Alloy. Alloy. You mix metals. Any There is no bonding between them. You can use metal Mix it. Lithium, Aluminum, Copper all Mix it. It will become an alloy. What did he become? Solid solution. Uniform Homogeneous. solution if you are talking then i I am talking about the true solution. Number One Highlights of number two True Solution There should be a uniform. being homogenous Needed Uniform distribution everywhere Should be. There should be a single fuzz. correct what's the matter? And if it is correct then this is in the alloy It will apply. So this is also a solid solution Example of. of equivalent gaseous solution You can take polluted air as an example. what can I take? Polluted air. Tell me what happens in polluted air? Air Take a sample of . There is wind. Isn't it? It is air. A little SO2 got dissolved in the air. So what even is SO2? There is gas. Inside the Air SO2 got mixed. So what happened? Polluted air. Now tell me that polluted air what will it be called? what is that polluted air Will it be called? Is there a uniform? one everywhere As is the distribution. is homogenous, The single is fuzz. So what will that be called? They is also a solution. That is also a true solution. But it is gaseous. So what statement do you Did you understand it? Did you understand the statement now? Let us move on to the next statement. Statement Let's move on to number three. Let's move on to statement number three. The next statement is. Take the next statement. Statement number three. The next statement statement number three says that The fuzz is of the solvent and the solution No, on statement number three. How to identify who is the solvent? First What is identity? The Fuzz of Solvent must be similar To the end of the solution. Tell me what kind of statement is this brother? Solvent's Fuzz It should be the same as that of the solution. Homogeneous means single everywhere The fuzz is on. Single fuzz right? Uniform means uniform distribution. this also is the correct statement. So whenever you go to identify Who is your solvent? So the solvent The one whose face matches the solution. Is No? Must be similar to the fuzz of the solution. It is an equal thing. There is a little bit of lag bhaiya It will be managed in some time. don't tension Take it. It happens sometimes. Isn't it? Ok? Keep reading. There is a little bit of lag Is. Let's move ahead. Is this much clear? so you When do you identify which solvent is yours? In me the solvent is only that brother whose fuzz Matching with the solution is the first identification. And If both of them are matched, right? If two If people's matches and everyone's fuzz are matching then You can call the person whose amount is higher as solvent. I will agree. Does this make sense? You Whatever you read here, tell me it is true Which one is inside the solution? Three statements. Did everyone understand the first thing? Three Did everyone understand the statement? So in case of solvent what happens first Will you see? First we will see the face and then fuzz will match everyone She does. So the one whose amount is more shall be considered as a solvent. Is it clear? Ok? Now let us look at what we read here Tell me, what does he read? True Solution So, I am reading it. Within the chapter we what are you reading brother? True Solution. Which one are you reading in true solution also? are we? We are studying in True Solution People Binary Solution. what are you reading? Binary Solution. Binary Solution also in our syllabus. What does binary solution mean? Most of the questions require you to solve binary problems. see you. Meaning of Binary Solution Binary means which has two components. Two Comonent. Two components. What would be the name of a component, brother? Solute. And what will be the name of the second component? Solvent. Solute and Solvent. These two components We will meet and talk to you. you this We have to understand who is the solvent? So what Do? Check the fuzz first. Cuckoo Fuzz The one that is matching is solvent. if both of the fuzz matches the solution then whose If the amount is high then it is considered solvent. Is the point clear? At once. Now tell me, in this chapter gradually I I am going inside. Isn't it? First of all What did I tell you? Where did you start from? Narrate. Where does the chapter start exactly? did I? Please look, please look brother. To all What did I teach you first? Mixture. How many types of mixtures are there brother? Mixture How many types? Three types. Isn't it? So which one is the first? True Solution. Which is the other one? Colloid. third Which one is it? Suspension. then tell you what Did I tell you? Colloidal is not to be read. Suspension is not to be read. what do you read Is? True Solution. Then I said True When you start going inside the solution, tell me What I told you inside the True Solution told? Some statements. The first statement is A solution is a mixture but every mixture is a There is no solution. Second Statement The fuzz of the solution is not necessarily It is always liquid, solid or gaseous Might be possible. The third statement is that of the solvent Should match the fuzz solution. so much talk Is it clear to everyone? Now we are studying binary The solution has two components. Now we are true Let's go inside the solution. I had said You don't necessarily need the true solution It should always be liquid. it could also be solid is and he Can also be gaseous. So let's go to her Let's discuss inside and take it further. like me Here I tell you, please listen carefully. Solution Solvent Solute. Now listen carefully. accept it I told you as I told you That solution can be anything. Isn't it? So tell me the solution, can it be a liquid solution also Can. so in the first case what am I doing Am? I took this liquid. what is the second case Is? Took a solid. What about the third case? took it? Gaseous. tell me solution b May be liquid or solid or gaseous. Isn't it? What shall we name the first one? Liquid Solution. Liquid solution. what about the other one Will you say it brother? Solid solution. So this is it Solid solution gone. Come to the third one. What's the third one? Gaseous Solution. So this is the gaseous solution. Is it clear? Now tell me what kind of solvent is there in this Will you take it? Solvent What did I tell you? The solvent is the one whose fuzz matches it. Isn't it? If this is liquid then tell me this also How should it be? Liquid. if this is solid If yes then tell me how should it be? Solid. And if it is gaseous then what kind of thing is it Should it be? Gaseous. Do you understand this does it come? So the solvent is that which has a fuzz Match it. Who to match with? With whom? match brother? With solution. ok now tell me after that The next point is what are the solutes Can you take it? So if someone asks you What solutes can be taken? What solutes can be taken? so tell What solutes can be taken in the first case yes? you can take anything and whenever Brother it can be solid or liquid also It could be gas as well. Solid Liquid gas, solid, liquid gas. What Are you getting the point? so salute you some You can take it also. But the solution and the fuzz of the solvent needs to be matched Is. Is it clear? three things? Come to the example. Isn't it? Now inside these Let's walk a little. Now tell me which of these We do not need to read in detail who they are Are you from? Tell us if we have liquid Do you want to read the solution? or give us solids Do you want to read the solution in detail or tell us I have to read Gasius. tell me about the solid solution Example: What did I tell you? Example What did I give as an example of this? To you? Alloy Isn't it? What did I give you as an example of this? told? of the gaseous solution. Polluted Air. So should we read all this or not? There is no need to read in detail. Because it is It is of little use to us. Who is of use to us Any question regarding this? Main our target Who is it brother? this is our main target Liquid solution. So now tell me about the chapter When we go inside, what will we read next? Let's go? Will you read liquid solution or solid Will you read the solution or the gaseous solution will you read it? Type it quickly. Are you going to read in detail brother? Tell me what are you going to read in detail now We people? Liquid solution. So the chapter's What else became of the name? Tell me brother what was the name of the chapter? The name of the chapter became Liquid Solution. Correct Is? So the name of the chapter became Liquid Solution. So where are we going now? Are? Inside the liquid solution. See I am slowly digging a hole. Is No? Now which one am I getting into? Inside the liquid solution. Now if I I go inside the liquid solution. Meaning I am going to talk about it. just its I am going to talk. So detailing on this only It will be. Now whatever detailing there will be, it will be on this It will be. Do you understand this? Now put it Liquid solution. Brother, keep sharing the session, it's a little If you like the session then please like it swing on the button with the hammer Hit him with bricks, but it should be like okay liquid Let's talk about the liquid solution Let's start doing it now and go inside the chapter Brother, we have gone deep and are going to talk now We will provide you the PDF of Liquid Solution You will get it, don't worry, I will I will tell you how to get the PDF which will give you the viewer looking at the last Ok? Liquid solution. now come the chapter There goes our liquid solution. you ever If you read books then mostly in books The books start here. And Most of the teachers are XY All those things from Z Institute also started from here We do. What would you have named the chapter? Are? Liquid solution. While before that I have given you a lot of basic material. Gave. After that I am telling you. Now We're going to start with the liquid solution. You can see the books, it is written many times in the books This is the name of the chapter. not a solution It would have been written. what is written? Liquid Solution. So that chapter starts from here We do. Oh, okay. that chapter starts here We do. Equal Ok. Now tell me about the liquid solution when If we talk then tell me the solution now Has it been fixed brother? Narrate just. How is the solution now? All people type How is the solution now? It is liquid. So Do I have to take it liquid every time? Liquid liquid liquid. Now tell me someone I ask you what kind of solvent should I take brother? Solvent Tell me how is the solvent? The solvent should be the one whose phase matches the solution Do. Isn't it? So tell me if this is liquid So will you take this liquid also? this liquid So will you take this liquid also? and this If it is liquid, will you take this also liquid? This is understandable. Now come to the next On point. Who is the next point brother? Solute what to take? What solute to take? So tell me What solutes can I take? salute you You can take solid as well as liquid Yes, you can take gas also. take a solid once Take liquid once, take gas once Take. Are these three cases possible liquid? In the solution? Say. Now these three cases which It is possible for us to know these in detail Have to study. We will tell you about these in detail I had to read it. Now look, what is the name of this chapter Gone is the liquid solution. Now we get into the detailing We are going to do the liquid solution. Tell me, first of all talk about this case. How is the solvent? How is the solvent? Liquid. how is the solute? Solid. so in liquid Mix the solids. solid mixed in liquid Two. So tell me what to do? Urea in water Mix it together brother. Tell me an example of this. Example: What should we mix in water? Urea. By mixing urea in water you can Let us ask questions. So the questions they ask That is a question of liquid solution. in that The solvent is a liquid. How is the solute? It is solid. and the solution that is formed is It is a liquid solution. Is it clear? Others Come to the statement. The second statement tells you solvent if I take the liquid and I take the solute also in liquid form We will mix liquid in liquid. So benzene Please join me to Toulon my friend. What to do? Give examples. Add toluene to benzene. C6H5CH3 Isn't it? If you mix benzene with toluene then the matter becomes Will you go? This one is liquid plus liquid And this too in liquid solution. third Please give me an example. Take the liquid. Liquid Mix gas inside. Take liquid solvent And add gaseous solute into it. Look at the example carefully. So the example is My friend. Add N2 to the water. N2 Look, there is gas. Water is liquid. Liquid and What happened when you mixed the gas? Liquid Solution. it is clear Brother? I understand the session. You will find the content I am understanding it. Slowly in the mind When it is landing everyone will give a thumbs up Show me quickly. Brother 1.2 lakh people are watching and only likes There are 800. So does it mean that other people will have fun? Are you not coming to the session? bro 400 people Are you not enjoying the session? And If it is coming then break it brother then friend be stingy why do you do it? Hit it with a hammer. Yes. Now Look carefully. We call this a case Number one. This is case number one brother. This is our case number two. and this is yours Case number three. also if you wish you can note Do it and if not I will give you the PDF also Give. You can see it from there. no tension Not there. Focus on understanding. Isn't it? Focus on understanding. okay brother. Let's move on. now tell me when the chapter you If you read further then tell me in the chapter First of all, let us read this case. Water Plus we will read a case of urea. We are one Benzene Tolan will read Mila's case. And In the end, when the chapter ends, we will say this will read. What do you call this? Henry Law. When you find a gas in a liquid in water if we resolve then this is called Solubility of gas in liquid. And The case of solubility of gas in liquid What happens is called Henry's Law. This talk Does everyone understand it? Ok. Now take the discussion forward and write a question. Write down the question. So when the chapter ends then brother Henry Law It will end at. Isn't it? write question. I will give you the option. Everyone has to tell the answer. Read the question brother, read it quickly and whoever understands it, I am coming and giving you four options Please tell me or I am giving you three options Only two options are fine. either one of the two It's done. Question Mark: Tell me who is right brother? Type it quickly while everyone watches. Yes, everyone's answers should come, brother. quickly Everyone should get their answers. the question carefully Read and tell me. sugar water will you take sugar or water Brother tell me do you think sugar is syrup What is a simple example of sugar syrup? it's like you make syrup, you are there, accept it If you are frying jalebi then brother read the syrup take it otherwise you will have to filter it later Suppose you are making jalebi then say My podcast will happen, brother, what's in it There is a lot of water in it Add sugar and make syrup. So The question has been asked that if you have diabetes They are sitting making syrup which is a It is a liquid solution. Isn't it? inside that which The cane sugar you have added is 60% w/ W is in the solid state, and 40% of your share is water which It is in liquid state. So tell these two Which of the following should be considered solvent? Understanding the Question did you go? So see what is the confusion? One's amount is more, one's amount is less Is. Tell me whose amount is more? 60% its share then its amount is it too much brother? Its amount is more Is. And tell me 40% share is of water So its amount is less. So what is the confusion It happens to people that brother whose amount If it is too much then you can call it solvent. Do you think so? but so It is not there. Tell me whose amount is more? If its amount is 60% then you will feel this Is too much. Should I call it solvent? But It is not like that. What did I tell you? Tell me what did I tell you? Solvent He is the one whose Tell me brother. A solvent is that which has Whose fuzz matches. First of all you need to fuzz match Have to get it done. Tell me how is the solution? Solution How? Liquid. If the solution is liquid My friend, tell me who matches with Liquid? doing? Is this liquid from liquid? Is it matching? and if these two match If there is matching then tell me it is 40%. There is less share. but this is our What is? It is a solvent. So how many people Will you understand? Solvent our water. Did you understand it? Break it quickly. It is correct. Move ahead. Now let's look at the chapter, what we find in the chapter Did you want to study? True Solution. We take it inside Brought it. Now I conclude it once again Am. Concludes the whole thing from the beginning Am. Look, when we first started the chapter If we start then tell us from where? What was the first thing you said? first things first what did you say? Mixture. What did we say? Mixture. How many things are inside the mixture Did I say it? True Solution, Colloidal Solution, suspension. Correct? What we do not read this chapter? not reading colloidal, Do not read the suspension. then what did I read it? True Solution. then what did I Did? Understand some statements of true solution Take it. 1, 2, 3 then what did I do? True I told you about the solution that You read binary. There is a solute, a It is a solvent. Then what did I do? I Said that the fuzz of the true solution is necessary Not that it is always liquid. It's solid too It may be possible and it may be gaseous also. Then I gave you examples of all three. Out of these three, you will find solid and gaseous Do not read. Which detail do you want to read In? Liquid solution. then we liquid Entered the solution. of liquid solution Inside we saw that the solution is always It will be liquid only. Liquid, Liquid, Liquid. But even in that three cases can be made Are. Solvent, liquid but solute, It may become solid, liquid or gas. So these three We have to read the case. So basically in this chapter Do we have to read these three cases? Then when we came to this point, we thought of a question Took it. Have I finished what I said so far I also got it revised for you. Now we move forward I can, brother. You have understood the basics of the solution. Move ahead. endic concentration If you understand the basics then endic Concentration What are we going to see now? The Liquid Solution Inside True Solution are going to read. and liquid solution we are going to see his concentration inside Which is the binary solution. what are you saying am I? Inside True Solution, we I am going to read Liquid Solutions. he too the binary one with two components and its The concentration is worth watching. So let's go to his Look at the concentration. when we see his concentration So brother, let's come to the definition of concentration. Definition What is concentration? of concentration What does it mean? It is the relative amount. it is the relative amount of solute Present in solvent and in solution Please be careful when I say this Read what I am saying. I am telling that whenever you see the concentration that who Which is thick or thin solution then relative amount Please check the solute. What to see To you? Relative amount of solute. Whose In respect? Sometimes whose respect In? With respect to solvent. And sometimes with respect to the solution. See, you have also read about molarity in life will be. Big m and you may have read small m also. Everyone must have read this much in life, brother. Little If you are coming after studying then you can do it somewhere Have you read it from there? Isn't it? So tell me the molarity And in molarity you will know this much that what comes down below the denominator below it is a part in big m in capital m what comes down to is the volume of solution in The date of the litre i.e. solution comes What is the solution data in small m State the data of solvent Mass of solvent What is always relative on these kg The amount of solute is the amount of solute So what do we see about concentration what does it mean you have two boxes one x one y is asked which box is thicker Is it there, which one has a thick solution? What will I say to him? What will I say to both of them? Look at the relative amount of solute. Isn't it? In whose respect should you look? Sometimes You can also see it in respect of solvent Are. And if you wish then you can You can see it with respect. both to you I will give you an idea about concentration. talk is it clear? okay brother? Now let's come to units. Concentration Let's talk a little about the terms. Which concentration terms should you read? Are? What do concentration terms mean is it brother? Did you understand the meaning of concentration? Did you understand the meaning of concentration? What do concentration terms mean? Any Suggest a term by which we can express concentration Can represent. can you tell who is thicker solution and which is a dilute solution. Make a list. The first name is gram per liter. It is called its other name Strength. This is called strength. or capital S You can represent it like this. Correct? Come on to the other one. Second is percent w/ w third yes brother percent w/v next is percent v/v What else do you need to read in the list right now? You will read everything in detail next Molarity is to be read The big M represents molarity This is a symbol, you have to read the next one Formality Let's do the formalities, not that one bhaiya Isn't it the next one? Take it, the next one is normality. Capital n Next you need to take molality molality m and go ahead then you will get You have to read it when it becomes yours. What is PPM and what are the readings in PPM brothers w/w/v and v/v three reading Are. Correct? After it is yours What do you want to read? Mole Fraction. Mole Fraction. Then next you have to read volume strength. Volume strength of H2O2 solution. Make a list brother. Volume strength of H2O2 solution. So much You have to read it. Make a list of everything quickly. Brother Share this session. if how many people Are you enjoying the session? So far we are the people I have read it for almost 45 minutes. You will get a session Are you able to understand this? Are you getting it? If the concept is clear then share it Brother. Don't be shy about sharing Needed And brother when the whole session is over then you Everybody must write in the comment box How did you like the session? It means that each person I am seeing 1200 people live. I need minimum 1200 comments You should do this after the session is over No, you will not run away, at least do this much Do something for us in your life at least So brother, I need 1200 comments What does minimum mean? How did you like the session? Ok. Let us go Come on come on brother let's go ahead. The next point comes Is. Now we will read them all one by one in detail. Everyone made a list. Come first. who is the first sa bhaiya? Grams per liter. Come on. who is the first Like? Grams per liter. grams to liters I understand. Come to see first. First is grams per liter. Ok? This is also called strength. Ok? Come on brother. Suppose it is written somewhere yes x grams per liter. what have you written? x grams But there is a liter solution. So I ask you brother Explain the meaning of x grams per liter of solution. What does this mean? So you will say This means listening carefully. If we take 1 liter solution. If If I feel like I could meet you brother, I will leave it. Have you heard a poem like this? Yes, the poet is saying these things there. If If this happens then that will happen. Ok? So It is like that. It is a conditional statement. This what do you say? that poem conditional imran Did uncle recite the poem to you? If you Come and meet me, leave the world behind. so what's in it bro Is? That is a conditional statement. 1 litre If you take the solution, you will get x grams You will get the solution. They are saying that if you don't take it then you won't get it. Some? I will get more. Someone please tell me brother I have 1 litre does not take the solution. I 2 liters of solution I will take it. So one person said I am 2 I take 1 litre of solution. Now tell me what will be? What will be in 2 liters of solution? These Explain it to me. So tell me what is the price in 2 litres You will also keep x grams. no because attention Give me what is written above. Its What does it mean? This will tell you the thickness Used to be. He is explaining concentration to you. Do you understand the meaning of concentration? As You mixed green color inside a water. Made green color in a bottle. so this thickness you decided that i am going to do this I will use a darker colour. Correct? Now it is not necessary that you make the same in a mug That much thickness either you make it in a bucket or you Make it in a tub. This is not fixed. Any I can make it in. So when someone makes If you can, you can increase the volume No brother. You have to play more. Isn't it? So You make it in the tub. You have to play less bucket Make it in and if you want to play less, make it in a bottle. The thickness is fixed. The thickness has to be kept the same. So Tell me what will be the amount when you increase the litre Will it increase or not? x in 2 litres Adding grams will not help. 2 You will have to double the quantity in litre. So if you are 2 If you take a liter then tell me how much you should take Will it need? Say. Do you need 2x gram solute Will I have to take it? Is that correct? if you Give the next statement. If you are a 3 litre What will happen if we take the solution brother? 3 If you take a liter of solution, will you donation You will have to take 3x grams of solute. Yes and no. Is it clear? So what about the first statement can you write this with that also? write this too You can and you can write this too. All three You can write things down. So tell me what is it like Thousands of things can be written. then tell me x What does gram per liter mean? So this is a It is the ratio. This is what concentration means I am telling you a ratio. and this ratio can have thousands of meanings. the first one too It's ok. The second one is also ok. The third one It is also ok. There are thousands of such OKs. and such Thousands of things have only one meaning. If Someone please ask what does this mean? x gr. Per litre. If I write this to you then what will it mean it means? This also means x gr. Per litre. If I write this, what does it mean? This also means x gr. Per litre. So I what did you say? I said x grams per liter can have thousands of meanings. But all of them There is only one meaning of meanings x grams Per litre. What can I say if you get this line If it is visible then we will say x grams per liter. These Even if the line is visible you will still say x gr/ This is a Litre. Even then this line was spoken, it was x gr. But Liter. And I can write thousands of such lines. So what will work? x gr. Per litre. talk is it clear? The class is for 2 hours bhaiya It will be. Sit with your heart in your hands. have read it properly No? I had told you earlier. I had already told you. class is strong It will work the way it does. There will be a 2 hour class. Let go. So you always see what you memorize People? As soon as we say x grams per liter, people immediately What do you say mean? Someone ask you x What does grams per liter mean? So your A line immediately comes out of the mouth. 1 litre The solution contains x grams. it is a bit necessary Is. You should say if 1 liter If you make a solution of this thickness then You will need to add x grams of solute. If you make the same consistency in 2 liters if yes then you should take 2x gram solute It will have to be what does it mean to do things over and over again Are the ratios varying? assume that you Let me ask you a question. Listen carefully. take questions 4 grams per liter NaOH solution There is so much information. Any other than There is no information. I have to tell you the mass of NaOH And I will give you an option. Options are 4 grams, 8 grams, 12 grams. Can't say. Type it. Everyone type this quickly. Type it brother. What will be the answer? So, I can't say anything about the answers. tell me the answers Can't. why can't you say it brother? After all why can't you say it? We Tell me why can't you say it? What Will you tell me brother? This means thousands, right brother? What does it mean in the first place? Tell. of 1 litre If you take the solution So tell me 1 liter solution. how many grams Will you have solutions? There will be 4 grams of solute. Is No? If it is like this then it is like this. if then if you 2 Taking a liter of solution, it is of the same consistency If 2 litre solution of same consistency is not prepared then If you made it, tell me how much would it be? So tell me what is the matter? 8 g of solute It would be yes or no. It is correct. If you take 3 litres of the same consistency Brother, make a solution of the same thickness You would have to take the answer. the data inside it I would have to take 12 grams of the solute Would have fallen. This is correct. so that means Salute, who is your brother? who salutes Is? If NaOH is a solution of NaOH then NaOH It is a solute. Water is the solvent. got a The solution is ready. So the amount of NaOH Anything can happen. Four and thousands more like this Meaning, can you write it? Someone ask you Tell me what could be the amount of NaOH? So You would say it could be 4 grams or even 8 grams It could be 12 also. till then this I can't decide unless you tell me this Tell me whether the solution is made of 1 litre or 2 Is it made of a liter or three liters or Made of four. if you fix the liter I can also fix the mass of the two solutions Give. But litre is nowhere in this question It is not fixed. in this question just what is it fixed? consistency. and if the thickness is fixed So you can create thickness in any. What should I say? a dark green colour you can only Can be made in a bucket, not in a mug Can, can't make it in a cup, can make it in a spoon I can't make it, I can make it in everything. So This means the amount of solute can vary Is. If you mix solutions of different volumes, Let's make it. Equal. Well pay attention here to the meaning of liters Give it. If someone says 4 grams per liter. Well, what are some intellectuals saying? Are? But the litre is still there. But a liter is Fitted to. So brother my friend this is a It is the ratio. Understand the meaning of ratio. 1 litre 4 grams in me if you assume for example Someone says it is written 4/1. now tell me 4 / 1 Does 8/2 happen or not? tell me brother 4 / 1 8/2 same thing. It is a different matter. That's correct. ok and here it is 12 / 3 Doesn't it happen? Tell me. So tell me if somebody says a I gave him a ratio of 4/1 writing 8/2 one writing 12/3 all three right or wrong all three are equal or they are different all three are the same all three are the same so 4 grams per liter is any one of the three tell me it is in it 4 grams per liter not in it What is 8 grams per 2 liters, so 4 grams But don't you have a litre? If there is 3 liters per 12 grams, then what is the quantity of 4 Is there no liter on grams? Do you understand how much? I came and said hello bhaiya, did the person who asked understand Was uncle all right? my ratio is Friend. Ratio. The meaning of concentration Ratio. you understand the thickness what is the thickness I am making it? How much amount should I make Yes, that will be decided, right? then the next Can you tell me the times? Pay attention to the ratio Any one absolute value is this ratio. From this, if you can find any one absolute value I want to tell you. Somebody should tell me only then when you need another absolute value You should know it. If you decide one, I will decide four I will tell. If you two decide then I will decide eight I will tell. If the ratio has to be kept 4:1. If you decide three, I will make 12 Give. So tell me what does it mean in any one ratio there is no single absolute value until can be removed unless the second absolute I don’t know the value. did you understand this Everyone? Let's go. Come on next. Next comes x% w / w The first one is done brother. The first one is done. on the other Come. Come on person w/w. Person w/w of What does it mean? Suppose you find it written somewhere x% w/w this is the solution. What does percentage mean brother? Meaning of Percent it happens that it is out of 100 percent out of 100 No? So out of 100 means you are in 100 parts will see inside. Isn't it? So w/w means what happens brother? Isn't it? w/w means mass within mass We will see. Ok? So tell me what will you write Brother? if we Take 100 grams of solution. if we If we take 100 grams of solution then will it put x grams of solute inside it will get? Is this correct? Tell me. w /w to see the mass inside the mass. w / w means percent means percent out of Looking at 100. What do you understand Is? But you can tell me its thousands of meanings too. Can be done. Tomorrow someone may say that bhaiya If I see it in 200 grams then tell me 200 grams what if i make a solution of Will x grams do the job or 2x? Will I have to add grams? You will have to mix it 2x. Only then will you get that much concentration. So what You can write thousands of meanings like this Are. This is understandable. So I to you what am I trying to explain is Ratios have thousands of meanings. Ok? Ratios have thousands of meanings. One of it Conclusion If you want to write then what Write? if you buy 100 parts 100 parts by mass take the solution so inside it you need x parts You will get the solution by mass. Does this make sense? Of this matter Understand the meaning carefully. This thing means If you take 100 pieces of mass According to the solution, you will find it inside You will get x pieces according to the mass of solute. Are you getting the point? pieces means you take grams here By Mass. By mass means any amount of mass Take the unit. If we take grams here then Take grams there also. Let's take KG here Take KG there too. take milligrams here If yes, take milligrams there also. if you are 100 pieces of mass will be collected from the solution so x pieces you get of solute inside it See you by the month. Is it clear? Ok? Study, brother. Study. Everyone Study. Isn't it? How many enjoyed the session? Used to be? Are you getting it? That's great Content. Ok? Suppose I tell you 4% Listen carefully brother. Some say 4% W/W NaOH solution. Ok? You have to tell the mass of NaOH Mass of NaOH in this solution. This is a question, brother. Ok? This is the question. now tell me what is the answer Will you give it? Will you give me four or eight or 12? Will you give it? or you can't say it, type it quickly Everybody type Sir Fufa's AIR 100 what upon arrival I will get respect guru respect then I will be in AI Bhaiya I am telling you that if you get a good rank then I will honor you I won't give anything away, I'll give you respect I will honor you with a garland Give They are saying give away tell me sir yours is good If you get a rank I will give you respect I will not give you respect, okay so if respect If I give you my respect then it will be a big thing Isn't this the car that went up the valley The matter is settled, I will respect it Isn't it okay, I can't say if there will be an answer Brother, respect is a big thing, isn't it? Look, the answer is I can't say it. Please pay attention. Now let me explain two things to you. if you If you are writing like this then it means that if you If you make a solution of 100 grams then tell me What is 4 grams of solution in 100 g It would be a solute. 4 grams of solute means Salute, who is our brother this time? NaOH If there is a solution of NaOH then Ok. If you are here in this case If you had made a solution of 200 grams and sat down Tell me, in 200 grams of solution will you find 8 Where do I get gram solute? I would get it. You can write thousands of statements like this. If it is equal then what would be the answer? They Then it will be decided. If I assume that tomorrow I am sitting here with 300 grams So tell me do you need 12 grams of solute Do I get it or not? I get it brother This is correct. Correct? Now tell me which of these is the answer Gonna tick we? Answer: Hum that tick do. The answer can also be four. Answer eight It could also be, answer could also be 12. You will know the answer when you decide that How many grams of solution did you prepare? He has this concentration. It is just that concentration is telling and the concentration when you decide the solution How much is it then I will tell you how much solute It would have been taken. So what is the answer still tell me Can't. important thing as an example But let's say there is a paper, right? One You got 4% marks in the paper. be careful Hear Ok? This is an example. accept it You got 4% marks. Correct? There was a paper. You got 4% marks in the paper. So if I May I ask you how many marks you got? I What should I ask you? how many numbers did you get Will it be in that paper? so what would you give me your number Will you tell me or ask me something? One thing is needed - your wish. I will give respect. I will not give the car, brother. Vehicle I will not give the car. I will give respect To you. Your rank will come, I will respect you Give. What am I saying? Your 4% numbers Suppose it comes in some paper. So I to you May I ask you how many marks did you get? how many Marks have you achieved? English medium? English speaks English. Brother English He speaks. how many marks have you Achieved? tell me tell me india wants to know how many numbers do you have then you will ask something will you tell me the number You should ask bhaiya how much does the paper cost what should you ask how many papers if the paper was of 100 marks then my There are four marks if the paper is of 200 marks my number is 8 hello everybody so paper How much are you out of marks, how much are you How many marks paper are you preparing? Four is percent Four is percent 100 If you take 4% then the answer is 200 If you take 4% then brother there are 8 answers. Paper It will be decided based on the number it was. Understanding Are you able to find it? This is what I am telling you here I am explaining. The percentage is decided here It means the thickness has been decided. You Decide how much solution you are making. Then I will tell you the solution. understand the point did you come? Did you understand it? What did I say? 4% Absolute marks cannot be told from the number Can. unless you are told that the paper What number is it? The paper is of 100 marks If there is 4% in it then it is number four. of 200 marks There is 4% in the paper so there are 8 marks each. Are you understanding the point? Let's move on Are. So you would understand this, this ratio would be Is. What is this that is written? This is the ratio. take it into formula Take it. I don't understand this in the formula Take it. You must have understood it. well it's fast You guys are there. If someone asks, brother please tell me its formula. I don't want to think too much. Isn't it? I have been told that brother you are smart you are going to K AKM class but Don't change, I have come as a promise Someone must have told you to become faster Don't come, I have heard that people there become smart If you are also going to the same person then tell me what to write above Tell me, won't you change like the weather? what will you write above mass of solute mass of what will be the unit of solute in the formula I am writing the unit of mass of solute Tell me what you will keep Guru tell me what unit will you keep Are whatever i hear you saying gram grams milligrams anything you should say unit anything will work here now see below Listen, this is the concept, you have to understand the formula People keep memorizing it, they will write it down throughout their life Mass of solution now ask which unit If it goes down then you will say the same one below The one you put up above will work, which one? The unit will work, you can put grams on anything put milligrams put kilograms anything Apply it, but whatever is to be applied above should be applied below You have to apply it, right? If there is a village above, there is a village below as well Gram. It is just a ratio. hey do you understand What? We have to see villages within villages. KG I want to see KG inside. Inside mg Have to see milligrams. So this means unit Anything above will do. but the same one below Anything that you ran above will work. into tax Give 100. This is your formula. So if you assume Your girlfriend has denied it Don't come thinking too much. have you heard You are going to AKM class. Only Bring the formulas. So take this to him For. Look, I just read the formulas I have come. Are you okay? you haven't changed You have gone Dev. Did you understand brother? Let's move on Are. Tell me is this a unitless answer or else Is the unit inside? What kind of answer do you tell me? Tell What kind of an answer is this? So brother this is unitless There is an answer. Why is unitless the answer? Because If there is gram on top and gram below then cut Will go. If it gets cut then the answer is units. Now the mind I will raise a question of yours. Answer when If it is unitless, then how is it telling about concentration Is? I should get up, right? not one in your sharp mind The question should arise. If the answer is unitless. If the answer is unitless, there is no unit. He doesn't even have a unit. Then How is concentration telling? are you understanding Point? So what am I saying to you? Value Suppose you have two containers. a box Here it is, here is a box. any of the two The solution is ready. 4% W/W NaOH in one Is. One contains 5% W/W NaOH. who has Is it a unit? Tell me which of the two has a unit? No one has a unit. of two No one has a unit. Who is fat? Which one is thicker? This one is thick. Hey, are you able to understand? Did you understand the point? unit for either is not with me. But the concentration Can I represent you? These people are not Can or could? So we can do it. I told you about the thickness. Relative Amount Where is the most of the solute? he told No brother. He did the work. so what to them Do you say anything? Concentration Terms. but this Can also be unitless. Point Clear Is? One likes are done my friend. Break it down a little more. hammer on the like button Hit me with such a blow. you can hit with slippers too You. But it should get liked. As many people Brother, you are reading, hit like brother. if you enjoy it Teaching is being done with so much effort. life palm I am teaching you by keeping it on hand. Let's go to the next But let's move on to this topic. Next is my friend x% w / V Next is X% w/ V listen carefully. I say you x% w/v Explain what it means. what does this mean brother? So this means that if you take 100 ml Let's take the solution. If you take 100 ml If you take the solution, you will get x grams You will get the solution. Pay attention to this One has to see the mass within the volume. what to see Is? Mass inside the volume. The meaning of W/V Below is V. Above is W. so what are you looking at Are? Mass. And whose inside are you looking at? V Inside. So, what will you write? how to definition will you write? If I explain this to you, you will say why me 100 ml 100? because looking at the percentage have been. If I take 100 ml of solution I make it then me inside it You will get x grams of solute. it is understandable Is? But if I don’t do that. I I make it of 200 ml. If I make 200 ml So within 200 ml I would get 2x grams of solute. is it correct? Did you understand it? and thousands of things like these I can write. Is it clear? come to the formula Go away. If suppose it is said at home that Don't want to go too deep? Yes, there will be percentage in the answer, right? Like 4% I told you that if eight out of your 200 When you get your marks, you are asked how much in percentage If I get my percentage then you will say my 4% Marks came. Even if you get 8 out of 200, it is still 4% It is Marx. So the answer will be percentage right? Will I not take it? I understood the point Everyone? So what are these which are written above Will you say it? These are ratios and the ratios How many meanings are there? Thousands of Ratios There are meanings. There are thousands of such meanings of ratio and those thousands of meanings have only one meaning There is a ratio. I started to understand the point now To you? Now take another question. one more question Take it. Suppose I tell you 4% W/V NaOH solution And I have prepared 200 ml of solution for you. has made. Correct? you need to tell Mass of NaOH in the given solution in the given solution You have four options 8 12 I can't say it, everybody put it on quickly put it on as quickly as possible Tell me quickly in answer chat Yes brother, did you get the answer? How many got their answers? tell me the answer this time You can't do that or will you tell me otherwise? So tell me this time Are. CNH2N-2 are you reading? You are saying it, please say it. So brother Will you tell me this time? See why this time Will you give it, friend? Because 200 ml is fixed for you I have done it, brother. 200 ml he Fixed the solution. that's what we ask I was saying fix it to 200 ml. I tell I will give the answer. Now tell me how to make 4% W/V also Is. He also told that it is 200 ml. The water is finished. If you take 100 ml then it would be 4 grams Would. If you are taking 200 ml then it will be 8 grams. If you were making a 100 ml solution So it would have 4 grams of solute in it, which It is NaOH. Ok? But if you buy 200 ml solution right here Will make. If you make a solution of 200 ml Brother, there will be 8 grams of solute inside it. This I am able to say it again because in front of me The party told us this. Front What did the party tell us? it I told you to take 200 ml of the solution We are there. I have taken up this case. This one If I have taken it. Isn't it? If you can find it. If he has put this then forget about the world. Then you can apply the deposit. But if he If it happens then you should leave the world alone. First Vote Leave it. Did you understand? Is it clear? Ok. Let's go. Ok? Let's come to the formula. So this time brother Can you tell me the answer? This time the answer is 8 grams Is. Everyone please do gram here. Is No? This time the answer in grams is 8 grams Is. The answer is fixed. take its formula You take it quickly. Isn't it? Convert to Fule Let's do it. Convert to Fully. see w/v's There is a formula. Apply the percent w/v formula above. Mass of Solute mass of solute in grams below volume now Do not do anything in the above Will apply. It has fixed grams below ml Volume of Solution Add these ml into 100 and apply this Formula. So if you assume that you don't have any brain If you want to apply it brother then take the formula. every I'm something for that type of person I will tell you. You take the formula. One is saying, Sir, please teach on the daily board only. Many memories have come and gone but this time you please come. This type of thing is going on with brother. Let us take another question. Okay, tell me does he have a unit or not? Does he have the unit or not? So brother It has a unit. Isn't it? check it out Do you have a unit or not? So it has unit. Why the unit? Because above is the running gram, below is the running ml If it is there then brother it won't get cut every time If you don't want to cut then don't think about it, cut it once If he goes, he will get it cut every time, it is not necessary Hey, he won't get it cut every time, he's a man becomes wiser Ok Write a question brother write a question the question you have is like this 300 ml solution of NaOH contains 12 g of NaOH in it then find out The Percentage w/v Concentration of Solution I want to tell you this brother, you have four options 4% 8% 12% or you can't say it, type it quickly yes brother can you tell me 300 ml solution contains 12 g of NaOH I want to tell you how much percentage is running The matter is in W/V right? Let's see this I have asked you about bar percentage W/v. Do you know the formula for percentage w/v? Use more formula. If not, then tell me What was the formula brother? what will you write above? Mass of Solute. How much Is? Mass of Solute. Look, find it. Look at this solute is 12 grams. What will you put underneath? Volume of solution in ml 300ml * 100 It was cut. 100 303 12 3 4% w/V this ans. What is easy to understand? What Answer the question without using the pen or using the formula Could it be imposed? or by using this formula Can you only ask questions? so the answer is no You can do it with formula also. Let us understand J Are. Jay says if you know the ratio, the ratio If you know how to play then watch it for ₹300 for ₹300 Or you get 12 marks in 300. If you accept that, then what is the question? how many in 100 Will you come? This is the question. in 300 rupees paper You get 12 marks. The paper was of 100 marks So how many marks would you have scored? Isn't it? So that's it So the question is. tell me can we divide 300 by 100 Can I make it or not? What to do Brother? Divide it by three. into what do it? Divide it by three. It is just a ratio. Here you will divide it into three. There are three divides here If you want to do it then divide it into three parts here also. End Done. It is just a ratio. So tell me in 300 12 is divided by 3, which means it is here 100. So what happened here? 12 / 3 ie That four is over. This is the answer. in 100 Four. How much did you understand? Well, mathematically if If you go, the question can be asked easily Without any formula. Leave it to me, understand it It has come. Let's move ahead. 1 hour 20 minutes session is almost over It is what I think. 1 hour 11 minutes. Yes. Correct. Are you enjoying the session? Move ahead. Pen tab is the best. Someone is saying the board is Best. Ok. Uncle, where can I write questions on YouTube? It is in the notes. what else should I write on the walls Question? Where should I write the question? You will write questions on the walls. Let's go. He is teaching so loudly. Gulu's throat hurt. I teach. You are saying the sound is low. Such atrocities So don't do it brother. is the sound good Brothers, tell me once. Correct? Let's move on. Next is x% v / v. Come on next. next is x% v/v vol/ Volume. If you take a case with volume up Are. The question comes to you x% p/v solution. Ok? This question comes up. brother says it means Explain. The meaning of this is what you explain You will say that we are talking about ratios again It will hurt, right? but this time with volume We are looking at the volume inside. So what Will you say it? If we take 100 ml of solution Are so inside it xml There will be solute. Is it correct? Ok? But if we have 200 ml here Let's take the solution. 200 ml of solution If you take it then it should have double quantity i.e. 2x ml. There will be solute. Tell me it is correct. And are there thousands of such Can we write a statement? This is also correct, This is also correct. And thousands of such things are true Are. You have already understood the ratio. Meaningful thing It is clear. now what can i convert into full Should I take this? Quickly. If this is converted into Phule, brother. So, what will you write? Look, is the matter clear? If we convert it into Phool then what will we write? See. If you convert it to full form and write it You will write percent V / V = up Volume of solute. Tell me the volume is off In which unit will you take the solute this time? Which unit will you install here? Which unit should I install? tell inside the bracket Above. So you should say anything will do Here. Isn't it? then ask which one below Will you apply it? then you will say the same thing below What you have said above will work. So if the above If you have taken mn then take mn below also. If you take a litre on top, then take a litre below as well. Is No? There is no problem in that. equal thing Is? So don't memorize the concepts. this matter The ratio is going on. If both volumes If there is volume then it is bound to be cut. in that There is no problem at all. ml then ml litre Liter. Is it unitless? Isn't it? Is this a unitless issue brother? So This is the case you got next The formula has arrived. and this time also is unitless. Reason that the unit is on both the top and bottom The unit is being cancelled. So is this also What are concentration terms? But this unitless Is. In the 3% you have read so far Tell me how many unitless did you find? How many unitless were found? Two. Ok. Let's move on. Will you tell me brother? 200 ml of solution Inside 8 ml you get NaOH. So you Percentage B / B has to be told. We will get it cut. Four It will give you the option like this. Ok. Tell me what will you do? percent v / v Apply the formula directly. feels like you Too much of formula application. So up what to write? Volume of solute below 8 ml Volume of solution 200 ml 8 / 200 intu Do it. 100 Story Ends. From 100 it will deduct 2 and 8 4% v/v na Draw the solution. Now let us come to molarity. Brother Everyone so clear tenly molarity. Chalise And Ali Molarity What is molarity brother? How to calculate molarity will you define it? Molarity. well what can you do to fix this are you there? I have to make a solution. see the jugaad It will end straight in a line. j what does he say? J says brother give it 100 quickly Make it 100. If you want to see it for 100 then make it 100 Take. How will you make it 100? Jay says here Brother, divide it into two. what to do here Do it here too. There is a divide here as well The divide is over. Look, it will happen here 100. So what will happen here? It is the ratio Is. Eight out of 200 and four out of 100 will be finished Went. Look, the answer has come. Get it straight, brother. Let's go to molarity. Next program molarity. What is molarity? Look, we the people Made a list of concentration terms. See Here. Isn't it? Which ones have you done now? As yet? Look carefully. which ones did you do Out of it? The first is done, the second is done, the third It is done, the fourth is done. This much is done now. Now we Where are people going? On molarity. Molarity Let go if we come to molarity So molarity is represented by capital m. let's write the number once on top Tell us we will write moles of solute above Write down the volume of the solution in liters Equivalent volume of solution in liters. okay brother? This is the formula. In shortcut If you want to represent it a little Do you want to understand exactly what it is? So Write molarity like this brother. Write on top Moles of solute. Write down the volume of solution in litres. Isn't it? Volume of solution in liters. And After that, if I tell you, if Take the volume of the solution as 1 liter So, it is 1 litre, consider the denominator as I made a one putt so tell me then Are these moles of solute and this molarity Will the gifts be equal to each other? you can write tell then molarity will become equal to moles of solute to molarity When does it become equal to the moles of solute When is molarity equal to moles of solute? changes depending on the volume taken When what volume should be taken? 1 litre. Do you understand this? from this The definition is created. what is the definition Is? See Write molarity definition. You will get the PDF. don't worry take notes of. Isn't it? You will get the PDF. Molarity Write the definition. it is equal to The Number Of moles of solute present in 1 Liter of Solution Present in 1 liter of solution. Read What is he saying carefully? It is saying that If you take 1 liter of solution then its The number of moles of solute that comes inside Do the count. the solution has the same molarity of. As an example, suppose you have There is a container. Please listen carefully. One There is a container. You have found a solution inside this I have made it. There is a uniform. is homogenous. Meaning it is the true solution. talking about the same Is. I asked you to tell its molarity. This State the molarity of the container. Ok? How Will you tell me? Molarity? What would you do? It is a big container. if you accept it then you What to do with this? Just take out 1 litre. How much should I withdraw? from anywhere. well where Remove from? 1 litre. Remove it from here. Value Take a 50 litre container. So you can buy 1 liter Take it out from inside it. 1 liter from here Remove or take it out from here, from where Remove? or remove it from here or Remove from the middle. Where did you get it from? somewhere You can also extract it from . Suppose I here I took out 1 litre from it. 1 liter like me I will take it out from inside that 1 litre The number of moles of solute present in The molarity of the entire solution is. what did you say I have? Did you understand? What did I say? Whole There was a large solution chamber. Look, it's so big There was a chamber. You took out 1 litre from it Took it out. 1 litre can be taken out from anywhere Take it. from here from here from the shore from the middle Get it from anywhere. Isn't it? 1 litre Take it out. in 1 liter of solution in dissolved form of solute Have a look. That is the molarity. Whose? Same Whose molarity is it? This is what you have ordered for 1 litre I have taken it out. or the remaining attention Please listen to me. Now suppose if this There was a 100 litre container. Listening Carefully just. There was a 100 litre container. you have 1 liter Taken out. Saw the prices within 1 litre. So Molarity arrived. Whose is that molarity? This of 1 litre or of this remaining 99 litres or Then for the full 100 litres? Whose? Type it. Whose? Anushka is saying sir finish the class. Please. Tell me. Whose is it? It belongs to everyone. what will you say? It belongs to everyone. Correct Answer See what is this? If you have the concept If you understand it then you will say it belongs to everyone. Who I have taken out 1 litre of it too. which the rest of You left 99 liters of that behind too Is. and the entire 100 litres that was there earlier Is. How many understood it? Anushka I wish you were in the plus class there is no button here It is everybody's thing, brother, did you understand? Why does everyone have uniformity? Let me tell you the reason What is the reason, there is a uniform solution right? Brother, the uniform solution is the same everywhere If there will be distribution then if you take 1 litre Take it out and see how much value it has You are stuck, take out 1 litre, 1 litre The number of moles of solute trapped in the solution It is there, look at that. Who has the same molarity? This 1 litre and also the remaining 99 litres. And In fact if I could even take one drop of it I take it out from anywhere, even that The molarity will remain the same. Do you understand this does it come? clear. Let's move on. The next program is. Write down the question. Tell me quickly, everybody Tell me quickly everybody The guys from 1.1 are still live. from the beginning But till now it reached 1.2 and now it has become 1.1. So the likes of 1.1 are also visible. so it means ok matter. Everything is going well. read it properly People are living here. That's a good thing. Look brother, if I tell you the molarity of NaOH Ask the number of moles present in the solution Absolutely a mole right? you can't tell until you Volume should not be given. to understand this It hurt everyone. Now you must be starting to understand In my thought. Can't say. Ok? Let's look carefully. If I tell you I I am taking 2 molar solution of NaOH So that means if I buy 1 liter of it If I make a solution of 1 litre If we make a solution then it would have 2 moles Solute okay that means if I take 2 of NaOH If you make a liter of solution then the same concentration will be there Of So you would get 4 moles. Ok? That's correct. So I can write thousands of things like this I can because it is a conditional statement. tell me about this until you fix it I would calculate how much volume I took till then can't fix it. So tell me if there are 2 also Can. It can also be 4. how much is this will be? I can't tell you this until Until I find out what? Until I find out, brother How much volume have you taken? That's right. So What will be the answer? brother tell me. type it fast Everyone. What will be the answer? Can't say. Can't say. Ok. Go ahead. Here comes the next point. If tomorrow someone tells you Asked to explain molarity a little more. So above you will write moles of solute. Below You will write the volume of the solution These liters. Ok? If we assume that the molarity in it is These should be multiplied by liters So tell me, will moles of solute come? Equal. So if you look at the volume in molarity If you multiply liters then from here you will get See you moles of solute. If you put the volume in right here in molarity multiply ml So what will we get then? millimoles of Solute. Tell me what is the equivalent in moles and millimoles is there a difference brother? in moles and millimoles what is the difference brother? Tell me quickly. What is the difference between moss and millimos? What is the difference between moles and millimoles Brother? If you look at the moles and If you check millimoles, look at liters. And the difference between ml in 1 liter How many ml? 1000ml Isn't it? well in a single dose 1000 millimoles equals so if we look at the volume in liters If you take it you get moles. if you If you take the volume in ml then you will get equal thing Sir, today is Saturday, please leave the class early So brother you will be released only when I tell you 2 I earlier said that I would prepare for 2 hours come do it Isn't it, prepare for 2 hours and come for 2 hours I said the next question It will be 2 hours, it will be done by 9:00 pm right will leave Ok? Go ahead. Suppose the next program gives you a question that you have 2 molars The solution of NaOH is And volume of solution is 4 litres. You have to tell the moles of solute. tell me brother type it fast yes brother tell me if he tells you moles of tell me about solute then tell me moles of solute How will you tell me? What did I just tell you? In molarity If you multiply the volume by liters then Brother moles of solute arrive. This is correct. So what is the molarity?22 What is the volume? 4 litres. so this becomes 2 * 4 here it is8. Tell me brother is the matter clear? Is it clear? so if molar volume is good for you molarity volume if both things were given See if you can spot moles or not. Can you tell me? Understand what I am saying carefully. Now Feel it a little. what are these people Formulas keep playing within formulas. What did I say? If you have to calculate the molarity in I will tell you and also tell you the volume So tell me, are you able to spot the moles? Yes. Moles are able to tell absolutely. Why are you able to tell? be able to tell the molarity That means you got the concentration. What did you find? find out the concentration and thickness I missed you. Then when I take you along I will also give you the volume which is 4 liters so I will buy this I will also tell you how much thickness you need Do you want to make it in volume, in a mug or Should I make it in a bucket or a tub? I also told you in which to make it To you. So I told you the size of the container as well I told you and I also fixed the thickness Gave. So how much solute do you need to mix Mole? This will get fixed, right brother? Are you understanding the concept? Thickness is also fixed Is. How much amount of solution is to be prepared That too got fixed. so how much solute Whatever has to be inserted, it gets fixed automatically. So That's why I can tell you absolutely. Listen to me carefully. what do i say I have been. Absolute from any ratio It is possible to find out the value only when the second Absolute value should be given to you. whether a The ratio is x / y, right? x / y and you want that I know the value of either x or y Should I do it? I told you the ratio. Ratio If I tell you and both of them Let me tell you any one absolute value from this So you will tell the second absolute value. Did you understand this point? Is it clear? Ok? What kind of property is molarity? next Point. Brother tell me what is the molarity of the property Intensive or Extensive What kind of property is molarity? Intensive or extensive question mark Please type intensive extensive do you understand the Suppose I give you the option of such molarity What kind of property is it? Is it intensive or extensive? if you can't say then what will you tick Molarity is an intensive property, now ask you Ask someone Molarity Intensive Property Why is it so? Explain what is the meaning of intensive If it happens then come to the definition right Come to the definition when you come to the definition Definition of Intensive and Extensive So first let's be intensive on both definitions What happens? What is intensive? Let's see. So what is the first thing I told you about? Molarity Intensive Property. Intensive What happens? Listen carefully. Intensive properties are those that To Not Depend on amount and size come right at x What is Extensive? Which depends on amount and size. Brother, do you ever have trouble remembering that which one was n, which one was x, so How will you take care? my way of remembering Let me tell you. remember you all your life will remain. See which depends more It may be depending. Assume that every day you I am asking, where was your call busy, right? You don't pick up my number. Isn't it? You You don’t give me time. of my message Reply: Very much depends, depends. So Then what should I make brother? x more depend Depend means case x will be remembered? Equal So it depends more on whichever one it is, that is x Is. Did you understand the concept? I will remember it. Now I will remember it for life, I will never remember the opposite will come that he was in do not kiss depend kiss I was there more depending your phone was busy hello Assume your phone was busy x Isn't it correct logic, what is equal to the other So you understood the meaning of do not depend on these Do you understand, will you remember this logic, brother? Read in such a way in life that it lasts till your death Keep this in mind and do analytical things Do the factual things Ok. Now let's go a little inside brother. this is it Ok. These are superficial things. the definition is Everyone gets it written down. Isn't it? all the earth I am going to tell you. Why are you here? just Let's discuss that. Isn't it? Come on, listen carefully brother. be careful listen to me. When I say I am talking about intensive or I am going to do an extensive check. So the most The important line that is missing She remains like this in the concept of people. You Whenever you check this for a given sample Check it. What to do? for a given sample Check it. That is, when you take extensive or If you go for an intensive check, bring the sample with you There should be no tampering of any kind Needed Because if the sample is tampered with If it goes then you are not on the right track. They Right to do an intensive extensive check There is no way. Are you able to understand? Now let's dig a little deeper into this I understand. Let us take as an example Let's say I took a container. Listen to me carefully, very carefully. Isn't it? Suppose I took the container. This I created a true solution in a container Gave. ok brother in this accept that I said the truth Create a solution and take the values inside it that bh 10 moles of solute were 20 liters of solution made 20 liters of solution was prepared, tell me ok Tell me quickly how much molarity is 10 moles 20 liters of solute solution was prepared Tell me quickly how much molarity how much molarity Can you tell the molarity easily? What is the molarity brother 10/20 So the molarity has reached 10 / 20 10/20 means 1/2 molar solution 5 OK, now let's say I tell you that what does a person do half of this sample takes the sample. Half of this analysis That's not what I mean by taking it. Attention Please tell me that I deduct half the amount of the sample I threw it away and mixed it with water. anything like Not there. I just put half the amount in the analysis I am taking it. the solution is same i am doing analysis I am taking half the amount. So if If I take half the amount in the analysis then Tell me what will come in this half amount Is? What is going to come in this half amount? How many moles are going to come and what is the volume Is he coming? Tell me if 10 moles in total and I bought the amount size which is size half I did it. Isn't it? I halved the amount Gave. So tell me if I reduce the amount by half If I give it, will everything come in half? How much will it cost brother? how many in place of 10 Will the prices come? Five moles. Ok? And tell me how much volume will come? 20 instead of how much? 10. Are you getting the point? So if you look carefully here, you will will also be halved. The price will be 10/2. Keep listening to the talk carefully? Ok? 10/2 Mole. And what will the volume be? 20 liters by 2 This will be the volume of the solution. So much Do you understand this? What will be the molarity Brother? 10/ 2 / 20/ 2 So tell me will you take a two to two cut? so answer now That's what the 5 molar is coming. Everybody understands this I? That means even if I took half the amount So did it make any difference to the molarity? Did the molarity decrease? or molarity If it becomes too much then what is the answer? Molarity That's all that remained. This means by reducing the size by half, the amount Reducing the molarity by half affects the health There is no effect of any kind. it Is it clear? At once. Ok? Now, if you understand this She goes. If you understand this then the next point Come on pay. Let me know tomorrow if I take size 1/4 I will take it. Come listen carefully. size if I'll take 1/4. Someone said brother I I will take only this much. I will take only this much. If I could deposit that much amount I will take it. I made the size 1/4. Ok? I will reduce the amount to 1/4. Ok? I will make the size 1/4. Amount 1/4 I will do it. So tell me now what will be the mole of 1/4 Will you go? Those which were 10/2, should they become 10/4? Will you go? Many intellectuals are thinking here why don't you solve it again and again remained? Why are you writing 10/2? 10/4 why are you writing? If I were there I would have written it here 5 Straight. Isn't it? and I would write it here 2.5 straight. I am very fast. it feels like that You must be feeling it. Have you ever had such a misunderstanding I will remove it in a little while. See 10 / 4 right? How much is the volume? 20 / 4. Now! See, the misunderstanding will go away. So this happened Moles. This is the solution in litres. Now Also if you calculate the molarity then tell me in 10/4 he will take 4 cuts in 20/4 Answer is 5 molar still coming i.e. 1/4 size when I did it, still the answer changed It did not happen. now the next person says tomorrow Even if I do one, you will understand the answer There will be no change. Changing the amount in the answer It isn't going to make any difference. The thing is clear Is it happening? well I say this over and over again Why am I saying bye-bye? Please pay attention. Tomorrow when someone tells you that you once You take half the amount, once you take 1/4. Isn't it? you have a systematic amount This must be happening because you bite. Isn't it? So I told him you just cut it at random Take. Tell me what you want to cut. You you have to deduct a random amount random Cut the amount. What do you say you want to cut? I said brother this time random amount Let's cut it. How much is this saying something like this? How much is the total? You are telling me not even Address. I don’t even know how much it is. Random I have cut it. So cut it at random. to me I don’t even know how much it is. So I said I Took 1/nth part. just listen carefully I have to get into the concept a little. all this You won't get these things, brother. Playing with care just. 1/nth part done. Now that I have 1 / if you have completed the nth part then please tell me friend what is the value if it was 10 then now How many are there? Just type it, just see Is the brain working or not? Who How much were those prices? Type it. Tell me how much did it cost? Mole by mole. Molarity I am not asking. I am asking you the price. Tell me how much will it be per mole? What is the price of 10/ will it become n? Will the moles become 10/ n? Now you understand why I wrote 10/2 Had been? When I take half then bye 2 When I take 1/4 then it is by 4 right? So when I will take nth part 1/nth part so what Tell me? There will be 10/n moles. and the volume of What will happen? Please tell me about the volume. Volume What? It will become 20/n. 20/n litre. And Tell me when you find the molarity Molarity is that going to come. Why Molarity is going to be the same? because 10 / n When you divide 20 / n then n is cut from n Will go. The answer will still be 5 molar. By this I What do I want to prove? tomorrow if you Any nth part is also taken out as 1/nth Whatever be the part n, it will not make any difference to the answer It is not happening. By this I proved that No matter how much amount you withdraw tomorrow, it will be small Take out anything from small to big. One Even if you take out a drop The molarity is going to be the same. What does it mean Molarity does not depend on the amount. How many understood it? show thumbs up Quickly. Yes. Break the matter clearly. The concept penetrated deep inside. now what do you Did you feel the molarity intensity or not? Came? molarity intensive it felt like Didn't you come? Now you get complete clarity why is molarity called intensive remained? Why is it not depending on the amount Was? Pay attention to one more important thing. When I tell you intensive extensive So I wrote one important thing that People do not write. Isn't it? so called The intellectuals who are roaming around in the market they do not write, they write for a given Nobody writes samples. don't write books So he doesn’t write either. for a given sample Tell me why I am saying this? for a given Why am I talking about sample? to for a I am saying given sample because If there is any tampering with the sample then my Friend, that is the right way to do an intensive check Not there. If there is any tampering with the sample Went. What does sample tampering mean? What does tampering with sample mean? If you have some moles were mixed inside it from outside of solute. Suppose you have four moles of solute Put. This was considered sample tampering Will go. because if you match the price Then you thickened the sample. you own You are just changing the sample. then he is right There is no way. So no one from outside can come in Could. No one from inside can go out. Poem Did you hear this one, Rishi Kapoor is mine friend wants to say this in that he is He has been talking about intensive things since then. you say Brother, there are different things going on. They No one can come in from outside. no one from inside Couldn’t go out. Let's talk about these intensive things He is doing it. He is saying this from the sample There should be no tampering. Understand the poet What is the poet saying? Tell me in how many ways sample tampering can be done it occurs? Please listen carefully. of solute Even if you mix the moles, it will be different from the sample It's tampering. If we remove the moles of solute then There is also tampering with the sample. then someone's worth Do not mix. Don't remove anyone's mole. Done. The second thing is not to add solvent. Solvent must not be removed. Extra Water Do not put it inside it. and water removal Not even. How to delete? Do not heat it. What will happen if you heat it? Water Hut Will go. It will become thick. Tampering with the sample Is. Hello everybody? Are you able to understand? So Tampering with the sample means if from inside Someone came out, someone from outside came in Then it would be considered as tampering with the sample. And What would be considered tampering with samples? No heating, no cooling Is. If you do heating then water from here It will evaporate and go away. of the solution The sample changed. Even if you do cooling then something may differ. so this means heating There is no need to change the temperature. Heating do not need to do, do not need to do cooling, some There is nothing to be mixed or removed. all this There is talk about not tampering with the samples For. Is there clarity? Just a little more my friend 10 more minutes I will turn it off in 10 minutes. Isn't it? One Write down the question. Everyone take a note, brothers. Write down the question. 10 minutes more apply it now Today's class is only for 2 hours. no further Is. Today's class is only for 2 hours. Check it. 55.55 molar is the correct answer. how many people understand Did the matter come into play? How many people understood it? Tell me What does molarity pure water mean? If someone is telling you that pure water What does pure water mean? Please explain. Pure water means water in water It is getting dissolved and becoming watery. You must have heard the poem Main Pani Pani Ho Went. That poem is about this. that pure She is talking about. The poet is pure there Talk. When water dissolves in water If the water becomes water then my friend will be water It is a solute. Water is the solvent and This is the solution to this. So tell me if pure You are carrying water. of molarity What is the definition? then the molarity of The definition is 1 liter if you make a solution Let's take it. If we take 1 liter of solution then how much Mole is solute? That is the molarity. Isn't this what molarity is, brother? So tell me if If there is pure water then what will you see? Who is the solution? Water. So 1 liter of water Take it. Pure water. solute in it too Who is it? That is also water. then the moles of solute See for yourself. That means look at the value of water. So Tell me how many moles of water are there in 1 liter of water? If we find this, will we get the answer? Do you understand this? If you find this, you will get the answer Will go. Now tell me, would you hold 1 liter of water? Are. Tell me if you take 1 litre of water. 1 liter water means 1000 ml water. 1000 ml water. 1000 ml of water means 1000 Gram water. Why? why is that so brother? Because what is the density of water? Water The density of 1 gram per ml pure water is You are writing it down. Ok? So mass equals volume* Density. How much is the volume? 1000 ml Density How many? Multiply ml by 1 gram. Volume * Density. So 1000 gr. Water. 1000 gr. Find out the value of water. 1000/10/18 Mole water. And 1000/1 mole of water means 55.55 Mole water. It is correct. Is equal? So what does this mean as a conclusion came out? The conclusion was that 1 liter of water 55.55 within moles of water are obtained and for 1 litre of water The number of moles of water inside will be the same as the quantity of water The molarity will be. what is the molarity of water is 55.55 molar. Is it clear? ok why are you saying this 720 Have you given it brother? Why have you given 720? create For. You don’t have to become one. What not If you have not understood how to become then you do not want to become I gave you 720 just because my friend He is confusing me with the amount given Molarity doesn't matter What kind of property is molarity? Intensive and If it is an intensive property then its amount it doesn't make any difference take 720 take 18 Tomorrow I will put 50 grams of water here. Answer bean will come, should I add 10 grams of water, answer bean You will come because you want to see in what you You are looking for molarity, what is the difference from amount It depends how many moles are there in 1 liter We are looking for you sitting with this much amount or you are carrying this much in 1 litre The prices will be the same as they are getting now That's not going to change. Now a confusion Listen. What creates a state of confusion Is? Why did you divide it by 18? to remove moles For. What is this? This is the month. So in the mole Divide by molar mass to convert You will do it with water, right? from the molar mass of water They divided it. Tell me what is the confusion? just finish five minutes Brothers, people will be worried, people are in agony Brother, I am in agony, listen to a question, understand it I have come, then listen carefully to me What am I saying, if the water is pure then 1 how do you find molarity of a liter sol What does molarity mean in 1 liter Take a solution and find the moles of solute in it this is the molarity right so tell me if water there is only water, there is only water The solvent is water. The solute is water. The solution is everything, water. so you What would you do? how many moles in 1 liter of water is there water? Find this. because that's what Is? Solution. What is this? Solute. So You will see the value of water inside the water, right? It is pure water. Pure means nothing else It is found in it. So that is what I am looking for. 1 Took 1 liter of water 1000 ml water. 1000ml Water means 1000 gr. Water. 1000 gr. Divide the molar mass of water by 18. The moles came in handy. So solve this. 55.55 moles of water. In 1 liter of water, if this much The price of water is 55.55 so that's it is the molarity. Here at Fill in the Blank Tell me what did you feel? fill in the blank here I was filled with 55.55 There are 55.55 moles of water in 1 liter of pure water It comes. This is its molarity. And this The amount is not going to make any difference. Isn't it? Go ahead. Listen to another question. Chubta The question arose. What confusion is being created? could it? Suppose I take a container. In this I have taken 10 moles of solute. Ok? Made 20 liters of solution. Ok? Tell me what is its molarity? Molarity comes to 10/20 i.e. 1/2 molar That means 5 molars. Now suppose an intellectual He comes and says, brother, if you accept this I added water. How many liters? 20 Got a liter of water. Addition of water increased to 20 Liter. Please listen to me from here. First This solution was ready. I have 20 liters Poured water. If I can calculate the quantity of water in 20 litres then If I put more in it then the volume will increase It will go a little. How will it be now? What Will the container get bigger? 20 litres of water If you add it then the total becomes 40 litres. Now Tell me what will happen to the data? 10 moles of solute Were. So what if you poured 20 liters of water? Did the moles of the solute change? No. The number of moles of solute is still the same. The moles of solute will change slightly on adding water From. The number of moles of solute is the same. 20 Litres You added 20 litres of water. So What is the volume of the solution? 40 Liter solution is ready. This is called dilution. Now Tell me what is the molarity? what is the molarity Is it 10/40? Is molarity 1/4? What Is the molarity 25 molar? what is the molarity Has the reduction happened? Earlier the molarity was 5. Now Molarity became 25. So what is molarity? Has the reduction happened? now people here what do you Will you confuse me? You will get confused that brother You kept the amount low here. amount here Increased it. The amount has changed. listen to talk be careful. Added water. you say yes or no Go. What I am saying. What water is added to this solution? Yes. What Has dilution occurred? Yes. did the amount increase is there a solution? Yes. does the molarity change Has it happened? Yes. What is the confusion now? What Molarity changes as the amount increases Is? See the amount is increasing and the molarity Change is taking place. so what is the molarity amount But it depends and if it does then it is intensive How could you say it? if you did it then you were intensive How were you speaking? Did you understand the point? If you are raising questions and not intense then You have read earlier that it is intense. So What will you answer to this? You will tell me friend from the sample There has been tampering. what will you say? here The sample has been tampered with and the sample When tampering happens then molarity There will definitely be a change. Are you able to understand? Have you changed the sample here? What Have you diluted the sample? And when you dilute the sample then The molarity will change, right? This is an intensive check Not the right way to do it. These intensive checks Not the right way to do it. That is why I What have you got written in Clear Cut? which line People do not listen carefully that brother whenever If you check intensive extensive then here Should be written for a given sample. Because If you change the sample, you will There may be confusion as to whether the molarity Did changing the amount not change the situation? but it's not like that. That sample has changed. Is the point clear? Is the matter clear? So that's it for today I keep it brother. That's it for today Are. Enough is enough. So brother, if you like the session If you found today's session to be intense, If you like it then like and share it everywhere Equal Share it widely everywhere Share it everywhere you can You can share it in as many places as you want Yes, share it and everyone should comment on it Yes brother, this is something you must keep in mind Everyone has to write their comments. You can write your comments in the comments. Please give your feedback if you can use my code If you want to use it, this is our batch If you want to use my code then My code is J STAR LIVE. my code is J Star Live. If you use this code So you come under my guidance. You See, it is in the description box, right? Plus If you subscribe then these batches Phoenix 3.0 has just been launched from 27 June Batch the answer. and if you look in the description See, my link will also be pinned there. of the code. so from there if you go and it If you take the code then my personal mentorship You will join the group. from me Contact us and come for special classes And in the special classes I will tell you that What to include in a Personal Mentorship Group will be. Inside my personal mentorship group By applying this code you will join and that personal What all will happen inside mentorship brother? Doubt solving will happen. Isn't it? doubt solving It will be. It is about all the subjects, right? Physics, Chemistry, Bio, everyone's doubts It will be solved. you can contact me on call Can do it. Isn't it? You will definitely remain in touch with me. some thing If you have any problem, you can talk to me Are. So these are all features of personal mentorship Of the group. Whoever uses the code, brother J Star Live, please take that screenshot And came to my special class. there i I will tell you that further personal mentorship How to join the group. Everybody understands Did I come? If you find the session interesting then give it a try brother. People please like and go. Isn't it? Share it As much as possible. and everybody when the session ends I will do it once in the comment box Please do write how you liked today's session. What was the energy level? What was taught? How was the content delivered? Isn't it? how much do you Did you understand? Write down all these things So that we can know what is going on. Correct is it brother? Hello. see you next class In. That's it for today. My heart is sad but It is not broken. If the hope is just gone No. Hello Jai Bharat.
