Titration of KMnO4 vs FAS | Class 12 Chemistry Practical | Easy Explanation @a2zpractical991

These are the sailors of the Pasamori. Scalar liquid is a liquid. You are watching this This is an honor. It is a bath. Be going to make It's a hand. What about the dates? 3.92 planet Hello, kids! How are you all? I'm sure you're all practicing a lot for your upcoming exams. I will conduct practicals in Pressure and Niveave. What are you doing on the smart board, sir? Brother, come here for a moment to adjust the smart board. You know, I'm already in the lab. Everything will become clear through practice in the lab; it won't be fully understood here. But let me explain this one thing here, and you'll clearly understand what to do in practice. It won't become clear in theory here, but whatever becomes clear here, I'll give you that, and then in practice, it will become clear what to do. Do you know whether you are preparing a standard solution? If you are preparing 100 mL of FAS solution, check how many moles per liter (molarity) you need to make. If the weight is known, prepare it accordingly; if the weight is not known, you must find it out. If you don't know, look: 392 divided by 1 is 392. You'll make it in 100 mL. You'll make it in 100 mL. In what will you make it? Make it in a 100 mL volumetric flask. Then, what will you do? Divide 100 by 1000. If you divide this by 1000, you'll get 0.1, so 0.1 will be in cubic decimeters. Write it down here—whatever amount you need to prepare, just divide it by 1000. That's right. Your teacher said not to prepare 250 mL, so what about 250 mL? No, and you'll now have to heat it up to 3.92 What do you mean, are you referring to 3.92 grams of ferrous ammonium sulfate? And we have to disassemble it; everyone has to get prepared. I'll tell you how to make it properly. 3.92 grams, what should I do? I need to prepare this theory along with writing it. You'll need to write three marks, not just that, but you'll also have to prepare it alongside. Okay, let's move forward and see. How are you all? You must be having a great life. Definitely, make sure to tune in to the Radio T Practical. So, children, regarding your titration, let me clearly tell you that the titration we are about to perform I'll tell the children about ferrous ammonium sulfate; if I say "M" for it, then the children that in this titration what we are going to do is to determine the concentration of camphor for the purpose of But Cameno for Ye, the two of them will provide a solution to this problem. You won't know the meaning of "molarity," meaning you'll know the meaning of "caminho foro." We must take very good care of this thing, otherwise we'll be caught by the camera. Provide the meaning of "FAR" and the meaning of "FAS" which is given to us. You'll know what it means—when we rent out the zero point Zin, what do we do first? This standard solution is fine; fill it up to this line here, if you're going to do this. Once prepared, you'll receive three marks. Let's start then, first of all, we What do FAS 0.1 malls do? Are you preparing? We are preparing, aren't we? How much do we need to prepare? 3.92 grams. I already sent you the exact line. This is mine. The Vaz class is set, but the tire isn't working. If your tire is like this If you operate it, you'll set it to the "T" position, and the "17 grams" displayed will become "0" here, leaving just the symbol for "G." If I need more, then this tire isn't getting any better, my current reading is 17.1, so I'll add 3.92 grams of wax. What should I do? 21.1, what should I do? I'll pay the VAT. Okay, Phila, it's become 19. It's already 20:кри 21.3, okay? What should I do? The kid, this one is torn. I'll take it to my table. Now, child, whatever you've just pipetted, what will you do with it? You won't transfer it into this small beaker, okay? When you transfer it, the child will remain here with some salt, which won't be transferred here, so you need to desalinate it in water, okay? So just gently place it in here, okay? And we will gently shake it repeatedly, then transfer it into this, okay? That's right, the entire thing you've just done. What will happen to the entire contents of your beaker with the hole? It will be transferred. After that, add 50-60 ml of water. Okay? Then I will add 50-60 ml of water. I am going to dissolve this salt. Okay As you will dissolve this Okay? Okay After disabling It's yours. Standard measuring flask If you've reached this line, you've already liquidated the position. Filled out So, what does this 100 ml bottle become for you? It gets ready. Okay? How will you fill it up to this line? Okay? Just take this much water that there is a label Standard Measuring Flask She couldn't cross that line. Right? Your lower lip will become completely swollen. That's your standard measuring flask. Standard measuring flask There is a line here Okay? If you've reached this line Has made the liquid So I'll tell you a few things Like your colorless liquid Right? Colorless It's liquid. There is no color in that liquid. If you are looking for such a liquid You're preparing Make an FASVAC. So, check the lower measuring flask with you. What will you see? Lower Measuring flask Okay? That's yours. Kemaro Port When you prepare the FAS prep Not Afees is the stand In the measuring flask So these colorless liquids lives For Colorless Which one do you have? Watch Miniskirts Lower Minisix The posterior meniscus needs to be excised. So, add one more drop. A little bit of the lower part needs to be lifted up. What does the logger have to do on that line? I'll show you everything Practical ones look at it Looking at the practical It was practical. Because you need to find out its molarity, kid, this is what you have to do. You have to place the burette on the stand, and whatever number it has It's a horse, and what else is there in the courtyard? And go to the utilities earlier. Aang, you're the only one who truly understands me. And the bawd of the Rangi's bhisti is a woman of the country. And the open mode of the Rangi's bawa Now what should I do? Once this is reined in, our bad solution will be ruined, so we'll have to discard it. And on your way back, what do you need to do with the Cameno 4 in this bureau? Fill it out. But let me tell you one thing: always use the funnel. You should go to your in-laws' place, because the chances of this being successful are very low. Now I will fill this out, so when you fill this out, I will also tell you one thing. If you fill this in here, what will you observe here? In the alley, the woman said, "I am alone, O my dear, I am lost." What happened here, damn it, what's going on with this damn thing? What has happened here? This is indeed a serious matter, and I have already informed the concerned authorities. Now, remember one thing here. because if you always set it to 0 always colorless liquid, colored liquid So whenever we always refer to the upper meniscus, it is 0, so I am referring to the liquid I will adjust Caminofor to 0. And always remove the funnel, do all these things. Alright, let's go. Now, what should I do? Look, what should I do with this on Zedo? Here, I'll do it. Okay. Look at this Okay, alright So, color leakwater, so, arajeara Now what should I do? I'll open this knob. And I will not give Liquit, zero on zero, zero on zero. Okay? See, this liquid will reach zero on the scale. What should I do with it? I'll turn it into a doll. Alright So what should we do now? Conical flask, okay And what will we do in it? Ferrous ammonium sulfate, that is our Mohr's salt What should we do with it? We'll transfer it. Okay. So we have to go from one pipet to another pipet. And the one that flickers, up to 10 ml There's also a line here; if you have Pipetted this far along this line So this is 10 ml, the way to grasp it It happens exactly like this, index finger on top of yours It should be a place where you can release pressure. Deep pressure can be applied. And what can Liquit do here according to that calculation? You can do it, okay After going to our village, a little bit I can have problems, just a little, I'm here I do this, just a little bit When you visit my channel, you'll see Yes, you can also get it from there. Okay And just gently pull it a little. Fylge What to do, where to start, I don't know I'll take a little liquid here first. They say it's called Rins Prosas. So, what do we have to do? It's light, I'll handle it with KELL. So what should I do? Don't do it practically without rinse, otherwise an error will occur, okay? After rinsing, what should be done with it? Yes, it has to be thrown away. What has to be done? It has to be thrown away. I'll go there, I'll take out the papat, I'll take out the pipap, okay, you just make the reel and take it straight to the video. So, back again, what should I do with this? I'll print it out, yes, and this one, you don't need this I have to go to the line, the liquid is just a little above, okay, so I'm here When the cup was tilted, the liquid had already reached the side tube up to the yes line. Now I What should I do? I'll transfer it to Conical Fax. Okay, I'll transfer it to Conical Fax. What do you have to do to transfer this? Chake Laska will still work even if you didn't take a drop, because it's your error. After transferring, the child You are required to add a test tube of dilute sulfuric acid. You will receive 2 normals, which will be delivered to you as is. I have 2 liters of dilute sulfuric acid here. So, is it okay to add this to a test tube? I took a test tube. Because you know why to add it, so that when you perform the titration Caimen 4 and with it Thus, a precipitate of amino 2 is formed, okay And the other thing is, if it's black color, then it won't work. And the other thing that keeps happening is in acidic conditions Caimeno 4 is fast oxidizing. works in a manner similar to agents What do you do with this test tube? Add it. Now, what do you need to do? What needs to be done against this is to perform a titration. How long should you perform titration until you get a pink color It's okay if we don't meet, let's go then Now we will start performing titration. So what do you have to do? Look, this left hand here—completely You need to grab this knob with this hand. You should hold the conical flask with your right hand. And perform titration in a circular manner, gently. What needs to be done here is keep adding. Alright, so like caminofor If you don't put it in, it gradually disappears. What happens, child, yes It disappears, okay? OK You're seeing it as if I've made a drop This is my complete solution When is this light pink? Imagining light pink Light pink Stop 12.4 Whole 12.4 Light pink Whole 12.4 Bala But how long do you have to keep doing this titration? Let me tell you, look, just like your first reading came at 12.4 And the second reading comes at 12.13 12.3 or 12.1 You will have to keep doing the practicals until then. For example, if you have the practical performance and its reading comes out to 12.1 And came twice, 12.1 Then what could possibly happen is that both readings will match each other. So long as you don't get constant reading Constant means, for example, your reading comes as 12.3 So, 12.3, if you get it three times or twice performed That is what your constant reading is, and what is CBR I have done this practical once. If I get up to 12.4 Vaccine exactly So what will become of me? It will become the final answer. So what do you need to do for this? Back to you What needs to be done with the burette? Fill it up to 0 miniscus. What needs to be done up to 0? So What should I do? What needs to be done? And what to put back in a test tube, sir? Dalu sulfuric acids Not a drop of concentrate You'll get two normal ones, okay? I got the light Bing color again. And my reading, you know, from the back again Practical If this was meant to be a titanic I can't get it back from 12.4 So I have to perform back again Maybe the reading I have is Heading to gate 13, light 13 has arrived You did it a second time, you did it a third time Everyone found out. So you must do it exactly in this way What matters for a titan is not to be, but to perform. Some things are us Let's go to our smart board and take a look at it.df What are the importances and how are they? Something is here on you Kids don't understand, I'll explain it to them. I came here to see you from afar. Don't overdo it, don't overindulge Suluzian in Buret What was taken in the burette? Tell me. I took Sir Liao's Kemeno 4; I can write with my eyes closed. Kemeno 4 had taken it, sir, the packet solution in pipette, what was taken in the pipette? Sir, FAS was taken, ferrous ammonium sulfate; write whatever you want. Sir, what was in the conical flask? Tell me. Sir FAS was, ferrous ammonium sulfate was And sir, I had added diluted H₂SO₄. Indicator, remember that, kid The examiner's favorite question is Question 4. Itself acts as an indicator. Endpoint, how did you get this endpoint? Tell me. First, your liquid was colorless. And later, colorless mixed into what? light pink Who was mixed in it? It's all becoming clear, just keep explaining to us See you next time What is piloting reading? Pile reading, as my reading was 12.4 So, what reading is between 12.4 of which and which? 12 to 13, got it? So whatever pilate reading I get It's 12 to 13 I am As your reading has come up 11.9 So, what reading is between 11.9 of which and which? Just stay one's difference, 11 to 12 11 to 12 Alright, let me see how much I was given at the beginning? 12.4 Then the second time, it was 12.4 And the third time, you hadn't seen it, had you? 12.4—this was found. Now this is the initial It was zero zero when I started doing the practical performance. Now, look, what are these differences? If you subtract this from that, brother, even if you subtract minus, the upper one will still remain. You must surely know that subtracting minus applies to everything. What is CBR now? You mean Constant Buried Reading. What is the most common thing among these? What is the stem? Nothing to do, child. Wherever it says CBR, just write 12.4. Wherever it says CBR, write CBR. Then remove CBR and enter the value of X. How much is this? Just 12.4. That's it. Don't do anything else. Don't touch it. Move on. What's written here? CBR was how much? 12.4, right? Do you remember? I forgot, man. You remember, right? 12.4, so 0.2 divided by 12.4. Who can do this calculation? Who can do this calculation? My mobile phone went where? 0.016 That's exactly how it was, as shown, step by step, calculating to save it. If you have any doubt, sir, please let me know about the calculation part. There's a video on this channel explaining how to calculate the CAMEO Four Faces calculation using the Aji method. How can you do it? How can you ignite it? I've already made it, I've already told you, there's even a trick—go and check, you'll find it. You'll also find it in the playlist; add the calculation video too—ferrous ammonium sulfate, qualitative practical, so you'll get it. You don't need to make this; I forbid the examination. You'll figure out the practicals. How was the video? Did you see it? He's already familiar with this practical. Alright, I want to.
