Question paper pattern for 12th board chemistry practical exam #practical @a2zpractical991 #exam

So, hey guys and welcome to my channel, friends I am Sachi Supala, and you are watching the 8th year practicals. Friends, there were so many questions from you today that How are question papers set for the practical exam in 12th Chemistry? Which will be our final practical exam I will clarify all your doubts. So, today our topic is exactly this one. Format of the 12th Chemistry Practical Examination 2023 and 2024 So the practical exams that are going to take place for you from the first week of February How to be And how will the questions be asked? I will discuss everything here. This is related to Physics and the Andes. Check out all the videos you'll be going to. If you liked it, please share it with your friends as well. So come on, let me show you I will explain the question paper format here. You must be seeing the format of the question paper. Annual Examination Chemistry Practical That is your 30 marks. So, what's the deal with the rebel 70 marks here? 70 marks How many marks is yours? So 70 marks What do you have, so I'll tell you Your paper is worth 100 marks. What do you have among them? Your theory exam of 70 marks are and 30 marks of yours How many practicals will there be in total for you? 100 means your exam How valuable are practicals? If the child is to become past That's very easy for this. Because you are getting 30 marks in practicals And you need to bring 5 marks from the takkar. Then you will definitely pass. You have taken science in order to score more marks. So, 30 marks will be awarded here. For your practicals No one has the right to go anywhere. Alright, let me start for you. So the first question is First, let's talk about question number 1. This is your question number 1 What is this to you? Question No. 1 Look at question number 1, what do you get there You have a certified general. And the journal that belongs to you It belongs to E. Balbharati's textbook. They use E. Balbhar's handbook. You must know about this handbook. This is the handbook we use and refer to. Here you will get a total of 5 marks Question No. Look, friends Question 2 Question 3 Question 4 So, what will be the total? 30 marks But your Question No. 2 is compulsory. But the question number 3 that exists It has the friends lottery system And the fairness of this lottery system What do we have to do? Tell me, will you pick up this paper? In this, question no. 3, everyone What do you usually need to find out about Kameno 4? Molarity, that is, concentration. With whom is titration usually performed? How long will you be given auxilic acid? It will keep doing FPS to you. The KMNO4 versus you Your FPS was Moversault This titration is likely to appear in the entire exam. It fits for 10 marks. They give very little of the auxiliary acid. We give exactly zero. So you will do it and go. You will receive 10 marks here together. So that is your question number 2. So, what will be your 20 marks for 10-10? Now let's move to question number 3. But friends, If you want to learn about marking skills How are marks awarded in titration? So I'll also let you know. I won't do even a little bit for him. I'm making a full video about this, beat by beat. Please watch the entire video carefully. I will make this video very deep. So, this is your marking skill. As I have already mentioned The certified general that you have It will be worth 5 marks. And it is compulsory based on oral, 5 marks And your volumetric analysis, that is your titration How many marks is it? It's worth 10 marks. And how much time will you get in it? Two hours will be given for it. How much is it for 10 marks? How is Marx? How will you be given 10 marks? Alright, I'm going to tell you that thing. So, look, whatever accurate weight you're doing Then you get 1 mark for it. Now you have a standard measuring class. You fill the liquid up to that line, 100 ml. So, how much do you get for him, 2 marks. After that, you create observation tables. You know, you often have to write down observations while looking at the observation tables. How much will you get for him, again, 2 marks. And I told you one thing: this video was also skipped, please watch it entirely. Because if you look at it thoroughly, you'll know everything. You will not be allowed to bring the handbook into the practicals. Therefore, prepare thoroughly on your own. Without a handbook, you have to go into the practical exam and write down everything. I will make a separate video for him too. So, if observation is made, then 2 marks. After that, look here: you get 3 marks for the reading passage that comes to you. But how will they get 3 marks? Malu, if the examiner has set the reading, 9.5. The examiner set the reading at 9.5. And you've got 9.5, so you'll definitely get 3 marks. But if your reading is coming up and down above, So, how much up and down is coming so that you get 3 marks? So if you get a difference of 0.2, Then you will get 3 marks. A difference of 0.2, for example, if your reading has arrived, 9.3, 9.4, or 9.6, or 9.7. If the examiner has set it to 9.5, from 9.3 to but not including 9.7 If any differences are found, So, what will you get? You will get 3 marks. But if your 9.3 has dropped to 9.2, 9.1 Done, So you've got 9.1, So, 1 mark will be deducted here for you. I mean, you'll get 2 out of 3 numbers. Here, maalo, you've got it, it was 9.7 So, what will happen to you here? 1 mark will be deducted. I mean, I want to point out that, If the examiner has set 9.5 If you add plus 2, 0.2 to it, And then bring down 0.2, Then you will get full marks. But if you give it to 9.1, 9.3 laiya, 9.4 laiya, then it's okay. Here 9.6, 9.7, it's okay. But if you start introducing even more differences, I started making mistakes in my titration. Then, one by one, your marks will be deducted. So, how many 3-mark questions will you get for this? Now you will perform the calculation, for which one mark and always result. Friends, you always have to write the result, and you will write the result. So, you will get marks totaling 10 marks. So, this was your titration, volumetric titration, marks distribution. You maintain meditation here very well. How is this being given to you? Look, question number 1 and question number 2, I have discussed it thoroughly. Now let's move on to our Question Number 3, Where the lottery system is. Lottery system means that in question number 3, there are many questions. What will you get from it? When you pick up the question paper, That's when the decision is made right there. The vaccine, it's been kept there, staying put. Which questions do you want me to ask you? What are question number 1 and question number 2? Mandatory. Question number 3, which is ours, is chemical kinetics. Chemical kinetics means, look, chemical kinetics you have, You must have done the experiment with sodium thiosulfate. Together with SCL. Vaccines, one of which is the one related to chemical kinetics, There will be two or three chemical kinetics reactions in your book. This is what we usually get. the one with sodium thiosulfate What is yours, sodium thiosulfate N2, S2, O3 And versus SCL. You are given a total of 10 marks to accomplish this. How many marks do you have in total? 10 marks for doing this. 10 marks means, You create a graph. You write your marks, your result. We will create a marks observation table. How are you doing the practicals? He also has 3 marks. What has been given for 10 marks? It has been awarded 10 marks. It becomes very easy. You will keep seeing a white precipitate. When a white precipitate forms, The time needs to be changed. So it's done. If you see it, It is part of the auror system. When you have obtained answer A for question no. 3, So it will get 10 marks. But it will keep being ticked. In question no. 3, option b will be marked. So it will go for the electrochemistry experiment. What is not done in college So, don't take it that way. Come here, and what might I be able to get for you? So it is C for question number 3. It will keep ticking for you. As chemical kinetics won't be ticking anyway, Qualitative analysis will be conducted. So, the qualitative analysis that takes place, It enters two basic radicals, Two basic radicals mean you have to start finding two ions. Then if you don't get chemical kinetics, What will you get in the lottery system? In qualitative analysis, to identify two basic radicals Now let's move forward. What else has been included in this lottery system? So, all the practicals included in this go forward, If you are into qualitative analysis No basic radical found, So, will you get it? to find out anions So, how many marks is anions worth, six marks? The remaining four marks ahead, You will get an activity. Will you get functional group detection? Those two marks, And with him, you will meet carbohydrates, proteins, and fats determine So, how much activity will you get? How about functional groups or carbohydrates? Protein and fat tests will be available, How many marks are they? Two-two marks, Now let's move on, If even that is not obtained by you, Then what will you get? You will get thermochemistry, The same applies in thermochemistry as well. In thermochemistry, You will be subjected to the Thane experiment. dissolution of CO-4 heat of neutralization HCl and NaOH Okay, CU by Zinc You will add copper and AgZinc. And you will determine the heat, You will determine the enthalpy. Then they will give one experiment from among them. You will get 6 marks for this. So, 4 marks are Kangas, You will have to perform an activity. You know the activity, Behind many activities, Or, you will be asked to test the functional group. Test 2 for carbohydrates, proteins, and fats 2 marks for this, Batlab. And for this, 2 marks, So 6, 4 will be 10, If even that is not obtained by you, So what could you possibly get? You might get it. inorganic and organic preparation Now, how many marks does inorganic and organic preparation carry? Maximum 6 marks You don't know, show What is inorganic and organic preparation? So you're orange red must have made dyes It is your organic preparation. You are Asita, Anili, Din We will be creating reactions Whatever you may be They create accounts You will be creating an account for Like Orange DC It will be total if it's being made. The molar salt preparer will be preparing. Double salt, it is an organic preparation So if you do all that preparation If you manage to extract good crystals After filtering and doing this, you will get 6 marks for it. And what will happen to the PiR 4 marks along with it? I've already told you, so you'll have activity. You will have functional group analysis. And 2 marks, and what else will be with it? Carbohydrate, protein, and fat tests will be asked for 2 marks 2 marks, okay, now coming to that if, okay That was it here. So, you'll show me the front then In question number 3, there were many varieties. Now they have understood so many varieties Either you will get chemical kinetics Either you need to find two basic radicals It could be, all of these are worth 10-10 marks. If chemical kinetics is not obtained, basic radicals will be obtained. 10 marks if basic radicals are not found Then you will obtain anions. For finding out, how many marks do anions carry? 6 marks. Then where are the 4 marks? That's when you'll get the activity. And if no activity is found, you will proceed with functional group detection. Here is your 2-2 mark. Now, people are asking a lot about marking skills. that in salt analysis If you tell me your marking skill, I'll also tell you mine. Let me tell you, marking, just like how you It will be found out through basic radicals. You get one mark if you perform a dry test. detection of the first group first group If you detect it You must have done group detection, SQS They pass gas, and so on and so forth. Add all of NH4, CL, NH4, OH So if you've already performed group detection Because you have two salts, such as Cu and Pb So, if you've already performed group detection for CU You will receive two marks. Anyway, if you have detection of the second group If PB's group has been detected Two marks for him too, when his turn comes. Group detection has been completed above CT. And finally, what do you write? result If you write the result, how many marks will you get? One mark. Even you have anions, then for anions How much do you get, 6 marks, so if you have Performed the dry test for anions, got one mark, then If the first radical is Detected, then a mark there, and its How much will I get if I do CT, same as before One mark, okay, so the first radical is If you have detected it, do CT then two Marx, second radical detected and CT performed So two marks, so how much has the charge become, and Now you have doubts here regarding the detection of the first radical. with CT, and you know, you Are you doing the weight test, or aren't you? Weight test, aren't you doing a weight test? Sorry, you are doing the weight test. No, weight test, then weight test if You've detected it, no problem A radical weight test is conducted at the tuba. So on the surface, you have one One gets a mark by cutting the paper with a knife. You perform the indivisible test, but for whom are you performing this indivisible test? If you detect SO4 and PO4, you will get one mark there. And if anyone is found in Gates' CT, then his CT will be checked. One max there will meet, one max like this will meet, two maxes can also be done for a sold, even for a dairy sold. This was the marking sketch for the solder analysis of the heat. So, fronts, there are many who feel overwhelmed when it comes to creating such videos and providing such content. And I won't even bother to adjust the video slightly to make it more practical or relatable to you. Check out this channel—it has all videos related to physics and chemistry. If it's not practical for practical, then do it later
