tysm, I was legit looking for this

I just accidentally skipped to the OCR Acids and Bases vid instead of AQA and has a major panic hahaha. 'Who the hell is Lavoisier and what the hell has he done with Bronsted-Lowry?! '😂 Thank you so much though for your videos, I cannot explain what a difference you have made to self-teaching. Fingers crossed for the exams now! Thanks again.

Hi there Just want to say thank you. Having a really hard time understanding some calculations in this topic and this really helped relieve a lot of that stress so i can go away and be able to practice them. It's the first time i've used a KZread video to help (I didn't think it would work) but it has helped me loads so you have gained a new subscriber :). Thanks again

I’m doing CCEA such a great help!! Thanks

Brilliant video as always

Sir honest you're the reason I'll get A* in chemistry because these videos are so much more helpful than my own classnotes😮.Thank you so much I now understand this topic.Keep up the great content 👍

Thank you so much for this. I was just wondering why sometimes (A)- represents the number of moles added eg if 5 x10-3 moles of NaOH are added, I am sure that sometimes I have seen that the conc of (A)- becomes just 5 x 10-3/vol, but other times, like your example, why does (A)- increase or decrease in moles eg why are moles added to the moles of (A)- when NaOH is added

my teacher didn't even teach the PH changes ... thanks for these videos

Thank you so much!!!

Is calculating the pH change of buffers in the OCR A spec, because I can't find it there or in the book?

For diprotic acids isn’t it 2x[acid]=[H+]

the best videos !

At the end on the uses of buffer bit, does the carbonic acid dissociate differently for the 2 different reactions?

Hello amazing video by the way, really informative!! I think at 21;35 I think I spotted a mistake you wrote "strong acids dissociate almost completely destroyed as it's dissociate poorly" but I think you meant weak acid am i right?

Does this cover the whole spec for chapter 20

GREAT VID THANKS

Amazing , thanks sir

How can we know whether an acid or base completely ionizes or not?

Goat, thank you

33:28 equation should read [H+] = 2[Acid]

Thanks Sir.

18:17 - Isn't water acting as the acid as it's donating a proton and B acts as a base as its accepting a proton?

So helpful thank you!!!!! :)

Hi Sir, I think there is a mistake on the acids and bases slide it should say weak acids dissociate poorly instead of strong. 🙂

Hi sir, do your videos completely cover the new aqa spec? and also how can i rearrange the videos to make it in line with the spec? thx sir i have an exam at the end of the month and i don't like the textbooks so your channel look like a great help!

Hi. I am looking to film new year 2 content including AQA however I have put this to vote. If you want AQA then cast your vote via my twitter account twitter.com/allerytutors/status/1258408810714140672?s=20

At 17:25 you say that BH+ is the conjugate acid because it’s a proton donor? Did you mean to say proton acceptor?

When calculating the change in ph of a buffer when adding a strong base, how do you calculate the moles of acid and salt after it’s been added?

thanks
