How to write Experiment in chemistry practical exam || part2 #class12thpractical @a2zpractical991

Hey guys, welcome to my channel, friends. Good morning, sir. I'm appearing for the 8th year practical. Friends, in the previous one, I told you how to write Mohar Salt in the board exam. I have already explained how to write the practical of USS titration. In this practical, you will Like cations that we have 2 in the Maharashtra Board To cation jo aapko milte hain aur usko kaise You have to write in the board exam, meaning you write during the time of the exam. How can we remember someone's words, what should we write when writing the result? Sari chiche mein ismein discuss ke How to write Tameno Four and Mohar Saul in board exams So, I made a separate video for him — please go check it out as well. How to write in board exams, okay, you're watching this video Watch the entire video, definitely subscribe to the video Let's share it with as many people as possible. Watch the full video and share it with as many people as possible, so let's go. So, whatever tests you have for the Aanec Faror Si Utoo Plus, I'll write them all. Go and see how to write marks, first of all You will hand over the color now, right? You will hand over the color now, then Pele, you put the heading, the first test, the test, then Color, if you see it as it appears to you, then color is whatever you perceive it to be. Assume that you are given copper for copper. You know that you're in a blue mood, copper. How is yours? If it's blue, then yours is Blue can be green. If blue color can be green, then what about the color of salt? It is blue, and whatever inference comes in, write it here. Look from here. Nature, you dissolve salt in water if you have salt It dissolves, salt becomes crystalline, and in crystalline form Whatever is here, write them down here in the inference, okay? So, in front of these. Whatever remains to be lived, that much remains to be written. Next is your turn, dry test. That your dry test on dry test will require you to write the basic radical What remains in a dry test is heating. Writing this as I am writing it myself: heating in a dry test Now you have heated the malo dry test, meaning you took the salt test. If you heat me and continuous heating in a blue flame, you might get this in me. An observation such as crepitation may be detected, as well as the formation of white sublimation. So whatever things you are receiving, decrepitation, secondly, what else are you receiving? formation of white sublimation, please write this down, and if you have anything else, please also mention it It seems like the colored salt turns brown and black upon heating, just as you would expect with salt. When heated, it's turning into black and brown below. You can write here and tell us what you feel about influence. What is in front of your decrepitation? Is it your PB, NO3, NaCl—everything is yours. What will happen if white sublimation is exposed to NH4? You will write NH4 plus may be present. You will write the entire thing as it is. It's not much—just a small amount of this wrinkled, shriveled thing. Just look directly, add the heading, what will you add for charcoal cavity test? charcoal cavity test Now charcoal cavity test, you know Cracking sound is coming, what is coming, cracking sound cracking means the sound produced; if you don't know I see, so my video on salt analysis You will go there to check out the case, a white residue is coming out. white residue means white particles are coming down, so you should address this issue Write about it, okay, and what is in front of decrepitation? This one junction is 없습니다, but PB is fine. Also present in K plus and white. What is in front of the residue: aluminium, barium, correct, calcium. So, what do you have inside it? Nothing to take out. Is it not that much ratio? Why isn't this mix working for you? Charcoal cavity test direct went felt like it needs to be cleaned The test for annuals—what exactly do you need to do for the test on annuals? It's about taking salt plus taking annuals in this. You will write on inference: moist turmeric paper turns brown Here we will write: moist turmeric paper turns brown and its What will happen to you, the inference in front of you, n h 4? Present and last flame test after that It will be a borax flame test, so you just need to write flame test. Nothing to write, write flame test, in flame test How should I write it? What will you write here? Do people cheat in OS and OS? It's a hot plate, and I'm heating it up. And after heating, what happens to this? Ammonia gas is released, and if turmeric paper is used When it turns brown, you will write the entire thing as: evolution of ammonia gas If you place turmeric paper here, you'll see that the writing has turned brown. Alright, so you'll write: group zero is present, group zero is What do you have now in Group Zero, John? N H 4 If your group zero appears, immediately report it to the city's chief. You will be assigned one city in the city, which I am assigning to you. OS Plus Nation Region, okay OS Plus Nation Region If my solution turned brown, brown means brownish. Here comes the brown pipiti and n h 4 Plus, what will happen to me? Confirmed, okay, so meaning whatever analysis comes to you there, you write city there, and that's it right here If you get confirmed, then you will write your salt. Done. Now we'll write the second salt. Ours is copper plus. Okay, Malo, I did the test and I got Copper Plus Two, so that's How do I know that your group analysis is correct? Is this yours? What is group analysis? In group analysis, in group analysis, you I have to write it line by line, meaning copper, well, I got it here, but I Here I'll show that I took the OS and applied the Daloit SCR. I didn't get the no white ppt, did I get the no white ppt for my group one? It will become absent; I'll have to show this, not that if I went to the second test, but when I found it absent, what should I do? Did you take the OS again and apply the SCR patch, applied the update, and passed the S2S gas? What have I got here now? Black PPT? What have I got? Black PPT What happened to me? Group two is present. Group two, what happened to me? Present. If you were given Group Two present, what would you have to do regarding its city, for example? If I don't get the black ppt, then what should I write? Group two is absent. After that, I would start the third one if I had obtained the white gelatin ppt. group Third is present, writing, I was about to go and change its city, but if this is not If your copper supply arrives, your supplements will also be exhausted, so you'll have to get another one. Exactly what should you do in it now, precisely as requested My copper has arrived, so what should I do with this copper? I'll make a city. To confirm, show the exact city here; certain cities are provided. Please redraw the three lines here again, okay? If this is what you meant Copper is present, okay? Then tell me what you do. Tell me about your black ppt. You take it, okay? Black PPT, you take it and then you... When you dissolve it in aqua regia, what is aqua regia? It has a specific concentration. Use a mixture of HCL and HNO3 in a ratio of three to one. What does "three ratio one" mean? Like this burette, it's three to one. You will have to take HCL up to ml, and for one ml, what will you have to take HNO3 in this? The white-colored ppt of copper dissolves now. How to handle the city that has dissolved, as mentioned in the above solution, you need to Taking the above solution and adding ki to it, if you wish Do the K4Fe(CN)6 one along with the above solution, which gives a chocolate brown precipitate. Meet or else do this one, check the above solution plus k4 if you like chocolate chocolate A brown precipitate forms, then your copper will be confirmed. above ppt plus if white If you get the PPT, what will happen to you, Cu? Plus 2 is confirmed, then you have to write it exactly like this, in case it's for me I don't get copper, does anyone get the third one? Does anyone get the third group? So I write something for your third group, one way or another. What is the difference between result and result? Should it be written like this? You have to write exactly as instructed, without any deviation. If any preparation is provided The preparation is worth 6 marks, and it will be included in question number 3. It will stay in question number 3, okay So if you get any preparation, please write its aim. Alright, write the aim, and directly write what you should write in the observation table The one you've got for making orange ratatouille Got it, got it for making Orange Ratatouille So, you directly write down its aim, okay? If the examiner asks about a chemical reaction, So whatever remains, such as 2.1, write it in grams; second, what is being asked? color of the two naphthol aniline dyes, and these will give you You have to memorize it by heart, okay? If you don't get this handbook, then whatever this is color of orange-red dyes, well then, here it writes, and How did you conduct the experiment? It carries four marks, and two marks are here for observation. And the result is achieved, okay, so the experiment you conducted, After writing M, okay, after writing M, you directly have to write the result. What do you have to write? directly you are given the result, the provided solution contains 0.1 molar SCL, and you are given The pipette you will prepare will be part of the standard measuring class, and it will be presented to your examiner. It's shown, okay, 100 ml, okay, 0.1 molar, okay, that's what you show your examiner It keeps showing up, okay, and the goods have gotten hold of some other activity, because it's been a long time. All the activities are done, so I'll let you know about it; meanwhile, the goods you need are activity number 4. So write the aim, okay, and create this observation table, create this observation table, and whatever is related to the remote It's coming in, 3.9, 3.4, you write these down, okay, you just need to write two things in here, okay, if you have this So, here are your marks, two marks here, to prepare two marks, okay? I'm telling you these things, okay? Now, with this Six, four, two, six, if you get six marks, and a four-mark activity will come, so sometimes What will you write, test, observation, inference, corrections, in the test, you will Whatever you have written will remain, whatever you have done, such as the substance I took, and in it Dodged it, 10% NaH, CO3, okay, and I got it. Briggs effervescence, did you get it, Briggs effervescence of CO2, you'll write this, What will happen to the carbonyl group, what will happen to it Say, I have to write the result for this, what will be written, what if you hadn't written the result. Topco So, you need to show phenol here again and then write the result here. Name of the functional group and structure: Here we write phenol And here is the structure of phenol. What will you do here, make it? Okay? Yes, friends, this one's yours now—2 marks worth. What do you want? Proteins, fats, and those kinds of tastes are good. Proteins, fats, and what else were done? Experiment Number 19 What? Now it's carb-heavy protein and fat Everyone gets the same thing, right? You get only one such person. Manki, come on, I've got it. Carbs, my present has arrived. Carbohydrates have come to my present. So how should I write this? You know, here we have to write the test Write the observation, write the inference If your starch presentation is due now So here is a starch test. Iodine-containing Alright, you need to take the substance. Plus, what needs to be done in it? iodine solution So if you get a lull color So, what will your star be NSNumber? Now you have to write the result here What should be written in the result? You will be writing the result from this You will have to write the starch. You won't find anyone like them. Do it first and mark it absent. And the other one, please. What is there in the other one? And your blueish, violet color matches So, what will your protein be present? Because you didn't write the result Then one of your marks will be deducted. So, what will you write in the result? So you have to write this down test, observation, inference Whatever it is, it's coming. Test just one thing You will be tested on this, and there are marks for it. And write a result on it, marks are there How else should it be written?
