Full Prep for the (Chemistry) Practical Exam + Solving the 9701/31/M/J/20 exam paper🧪🧬

[@zahra.rahman]

Heyyy, I really need some advice, would really appreciate if someone could help me out! I'm going to be giving my AS exam next month and rn I'm really conflicted to weather or not I should take the exemption ( basically if I take this my grade for paper 1 and 2 will be averaged and paper 3 will be completely excluded ) I gave a mock on both the physics and chemistry paper but my time management was really bad and I ended up needing 3 and a half hours for the chem p3. Another thing is I'm really not confident, so I'm worried I might mess up my lab exam which will affect my over all grade. I told my teachers this but they say I should not take the exemption and do the lab exam.

[@pip.pip.pooray]

Are you feeling more confident now?

@@AskAseel hey! Thank you so much for responding here! Unfortunately I didn't get any message from you on Instagram? Perhaps that was another account. But I'm happy to let you know that I ended up taking the exemption for my labs and scored A (85%) in physics, and a B (78%) in chemistry for my AS! I'm happy with my final decision as not taking the practicals allowed me to focus more on papers 1 and 2 instead.

Question, you gave a tip to do all experiments and recordings first right.. When there is a graph, should I skip it as well until I finish the rest of experiments and only then come back to it as if it were part of the calculation section?

[@AskAseel]

Personally I would do that, just to make sure all the experiments are done and out of the way so the only thing left is to to quickly fill out graphs and calculations. Just try not to take too long performing the experiements.

Hi, thank you for this video, super helpful!. I was just wondering if you could explain Q1 ciii in more detail, why couldn't you divide the mass of FA1 by the moles of KMnO4 x 5, (since the molar ratio is 1:5). Thank you!

[@AskAseel]

Hey! I’m happy to help 😊 Main reason is because the questions asks us to use that specific method and secondly because we don’t know what the molar ratio is. Since FA1 is just some random hydrated salt. (Unless I didn’t see where it said the molar ratio. It’s been a while since I filmed this vid)

[@BOBO_4869]

Thank you 🙂 I really think that this absolute uncertainty thing is rather confusing. Apparently it is completely different from Physics (they seem to not allow smallest division x 1/2), meanwhile in a Physics practical I wrote all my measurement results to the nearest measurement + 1, thereafter my Physics teacher joked with me about "having a precise laser eye that sees further one decimal place" 😂😂😂

[@AskAseel]

You’re welcome!!! Lmaooo it really is interesting 🧐 I wonder why that is 🤔 Maybe just different instruments?

[@BOBO_4869]

@@AskAseel Most likely... When I use a metre rule that measures to nearest millimetre (0.1 cm), the percentage uncertainty seems to be 0.1/value, (sometimes they even promote the estimation of absolute uncertainty between 0.2-0.5 cm). But I think the Chemistry way of doing it makes more sense as a buret can read a value of 0.05 when water level is at the middle of the two lines... Similar to a protractor, but they don't allow decimal places since the smallest division is 1° 😂

Hi. Why in 1c iii) Concentration is divided to 4? Also, why in 2 b iii) ionic equation of BaSO4 was written. Could you please explain it to me. I will have exam tomorrow. Thank you

[@AskAseel]

Hi, we divided by 4 since that’s what was shown in the marking scheme but it means the same thing as I explained at 12:00 with the multiplication by 4. So the general math rule where you divide by a fraction is the same as multiplying it’s reciprocal. For 3a iii) we were asked to write the ionic equation that’s why. It was also something we used in (3aii). Good luck on your exam❤️

[@lithium9999]

i have a question, but first of all thank you so much for actually solving a p3 without using the lab, was lost at first but you lead me into practicing it visually .. is there a way you could get a full mark in this paper by going through all of the papers and understand the how its structured or p3 is one of those papers where its impossible to score a full where it leaves you with one mark hanging for example, because my teacher said the highest she got was 37 to one of her students, so is there a way to beat the algorithm?!!

[@AskAseel]

You're very welcome boo. I'm sure you can get full marks, yes they take into account the teacher's values, but they also provide an acceptable range on how different your values could be from the teacher's. If everyone in the class got the same answer, except for the teacher I'm pretty sure they'll dig deeper into that or you can ask them to remark it if you've asked your classmates and you all got roughly the same answer. To summarize, you can definitely get 100% with practicals as most of the papers are identical in nature. It really just comes down to how well you perform the actual experiment i.e your experimental data and your stoichiometry skills.

[@questionabile724]

hi! awesome video but id like to ask if you could list all of the practicals present for as? we dont even do practicals in class so its kind of hard finding the practicals required..

[@AskAseel]

Honestly, the only way to prepare is through practice and self-confidence. If you have done these experiments in class then you are ready. I repeat, if you have done these experiments in class, then you are ready. The only way you can mess up is if you get in your own head and start to doubt yourself. As for the calculation questions, practice solving them with random numbers. What's important is understanding the method used to solve the question. Once you have the method down, the only difference between different exams would be the numbers you get. Believe in yourself and see the mock exam as practice for the real exam later on.

[@malektleti1284]

in 07:47 you said the difference between each titre is no more than 0.10 cm3, but in average, if you have titres that are within 0.10 right, why did you say average must be within 0.20 of the titres used.. so in the exam, lets supposed i did 3 trials, should i put the values i got that are between 0.10 within each other or 0.20???

[@AskAseel]

The reason I said that, is because in the marking scheme they are giving the examiners options to give you marks so if your titre isn’t within 0.10 cm3 they can give you a mark for the average as long as you choose the titres that are no more than 0.20 cm3 apart

the question 3 ai) do I have to record my excess observation here only? thats what I mean I hope you get my point 😂😂😂

[@linaabdelshafy6524]

how did i know that barium nitrate and hcl would be the suitable tests in question 3?

[@AskAseel]

From the question we are told that the anion is either a sulfate, sulfite or halide. So that means you’ll be performing a maximum of two tests. If you are lucky the first test will give you an answer. So for this question it was a sulfate so doing the barium nitrate test with HCL gave me the white ppt that’s insoluble in HCL. If it was a halide you wouldn’t get this observation.

[@zainabramzan403]

Is it wise to do the practical exam with zero practise before hand? I need help!!

[@AskAseel]

I personally wouldn’t recommend it. But do remember that the practical paper is worth less compared to the other papers. So you can focus on doing really well on the other papers and just do your best for the practical. You can watch videos and grab some fake equipment and sort of visualize yourself doing the experiment to build muscle memory

[@linaabdelshafy6524]

how about the reagents? will they be labelled fro us?

[@AskAseel]

Yes they will be 👍🏽

[@FalconEye2015]

Hi, I have to ask. Is it possible to get an A in AS level if I fail the practical

[@AskAseel]

Hey, it depends on the curve that year, so if an A is 80% then as long as you get an overall 80% with the other papers I believe you should be fine

[@unloved1827]

Could have been nice if the paper was filled with assumed values Anyway top work 👍

[@AskAseel]

I agree! Thank you tho✨

[@Xh-xg2ll]

Question to those who took it. How many times should you repeat each of the experiments for quantitative analysis?

[@AskAseel]

I believe I mentioned it in the video, but at least 3 times.🧪

[@Xh-xg2ll]

Yes, thank you ❤. I just thought that we have to repeat them only for titration, so means that it’s also applicable to the gravimetric analysis (mass related experiments etc.), right?

[@AskAseel]

You’re welcome 🥰 hmmmm I just checked a couple papers and it doesn’t look like you need to repeat 3 times for the other experiments 🤔 but it’s been a while since I did the AS Level exam myself, so if someone else who’s done it more recently can hopefully give a more definitive answer

[@Xh-xg2ll]

Thank you 🙏. One more question, before doing the titration, do you have to rinse the burette with distilled water or acid that you’re going to use to remove impurities or you can just proceed with the titration straight away?

[@AskAseel]

You’re welcome 🥰 your burette should be cleaned by your prof before the exam begins. But if u have extra reagents then there’s no harm in doing a small rinse with it!

Hi I have a question for question 1 what was the indicator. In other words what was the end point?

[@AskAseel]

You’ll know the end point when there is a colour change. That’s why in part (a) they ask for a rough titre. So you’ll keep adding acid at a faster rate than in the steps were they ask for more accurate measurements. Once you get close to the amount of acid that caused the change in colour of the solution in the flask you’ll slow down and start adding acid from the burette drop by drop. Lmk if that helps or if I misunderstood you’re question!

LMAOO sorry for the endless questions i keep asking, my exam is after tmrw so i wanna make sure i know as many notes about this paper as possible. i was gonna ask you that when we test a substance and a gas is given off, how can we determine whether its carbon dioxide or hydrogen etc..like i wouldnt be prepared to test for the gas immediately after its given off, like for example i use hydrogen glowing splint test or limewater? does this mean i have to repeat the experiment?

[@AskAseel]

Lol it’s okay😂 You’d most likely be given some sort of hint in the questions and if you check the markscheme for some observations it’s enough to say that there is effervescence without identifying the gas released. You might also just have to repeat the experiment.

Hi Aura, I'm sorry to know that you're stressing and that you don't have access to a lab or a good mentor.😕 I don't know of any simulations at the top of my head, but if you find some online I can take a look at them and tell you how similar they are to the actual exam. As for KZbin there are many great videos like this one: kzbin.info/www/bejne/qXfTd3aGiampaNk that can help you visualize how to perform the experiments. Like I mentioned in my video there is only a couple different types of experiments that you need to know how to perform so if you can focus on those, you'll do great! I hope that helps.
