Recently, my mental health has been horrendous due to examinations. However, your content has changed everything. I shall forever be grateful for your help.
why are your explanations so AMAZING somehow you seem to successfully explain things so well that no textbook could ever help me understand. And you give so much detail as well i love it thank you!
genuine thanks for all the help! I struggle so much with the maths in chemistry, and your collection of videos have helped me so much! wish me luck for my actual a levels 😢
Hi, 2 questions please. Number 1) is your content suitable for CAIE A level chemistry? Number 2) Do you have a specific video regarding titration curves? many thanks
Hi there, yes definitely suitable for that 😃 I've made a question walkthrough rather than an explanation video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4-S9uOSaSVg.html
Why do all your burette readings show the 50 cm3 mark at the TOP of the burette, and 0 cm3 at the BOTTOM near the tap? Every real burette I have used in my life has its scale running from 0 cm3 at the TOP and 50 cm3 at the bottom near the tap. The difference between the initial and final readings (the titre volume) is the same as you describe, but the scale on actual burettes is different from your description.
Sir i was wondering if rinsing the burette with the alkali solution ur using is viable cause that was something i wrote to increase accuracy of the final result instead of using only distilled water in the mocks😅😢
You shokld always rinse the burette with whatever solution you're going to put in it. You shouldn't rinse the burette with distilled water as that will dilute whatever solution you put into it, so your titre volume would be too high. The only thing you should rinse with distilled water is the conical flask during and after a titration
Not really... Paper 3 is a funny one in that literally everything could be on it. It's particularly focused on any kind of practical investigation... it doesn't have to be a required practical even, but a large part of the paper will be practical content. Therefore its really difficult to do a specific paper 3 list and expect to cover it all
hi sir this vid was so helpful! I was just wondering, how exactly does leaving a funnel in the burette decrease the titre volume, doesn't it increase it if there are drops being added. Thanks!
Thank you! Glad it was useful! The drops from the end of the funnel drop down into the burette. So it appears that less has been added than it actually has. Its a bit like the burette is topped up part way through the experiment
@@chemistrytutor hi sir! this exact Q came up today and literally remembered ur comment in the exam! ur vids are amazing and I hope to continue using them :)
Hi sir im a gap year student i got a c last year and im retaking alevels this year again i have fully revised all topics in physical and year 1 inorganic chemistry im gone start organic chemistry tmrw and i am doing past papers for paper 1 and also going over chem revise notes and watching vidoes o n youtube. do you think i have enough time to get a B grade in June? i have applied to medicine and need a B for my course :) I would appreciate any tips or advice. thank u! @@chemistrytutor
hi sir im a gap year student i had a c last year i need a b for uni could you please give me some advice and tips also im revising from chem revise and watching youtube videos and also doing past paper questions do u think i have enough time tto go up a grade by june?@@chemistrytutor
@user-dc8sc8tg7w it's a great question, and honestly it's quite hard for me to answer, not knowing you, or how well you're understanding the content right now. You've got 4 or 5 months until the end of the course, so there is absolutely enough time I'd say. It depends how you want to spend your time really and how confident you feel. My advice if you're confident, is to start with exam questions. Go looking for your problems. If you can do a question, great... you've learned something. If not, that's when you hit the books and try to improve your understanding
