tysm, I was legit looking for this

[@georgiapactor4790]

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.

My pleasure!

I was so confused on this topic before I found your video. Thank you so much for creating this online resource !!

[@AlleryChemistry]

You're welcome!

youre a life saver! I'm roughly a month off my exams now and I'm really feeling the pressure now.

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 KZbin 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

[@yaseenm1917]

A week away from exams - thank you, the video has helped a lot!

[@safa4806]

what did you get! how did you revise?

[@bellastarmartin4601]

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 👍

[@AlleryChemistry]

Thanks! You're very welcome 😀

[@idontknow1630]

did you get the a* then

[@zo.699]

I LOVE YOU SO MUCH THANK YOU FOR HELPING ME FINALLY UNDERSTAND

[@AlleryChemistry]

You're welcome 😊

[@rahanlol]

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

[@edward2291]

Appreciate your hard work!

Thank you so so much for these videos! They're so helpful! :)

[@Letik3x]

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

[@isaacrobertson4318]

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

[@ding-dongditch8773]

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

[@callmewhateveryouwant5263]

thank you sir you absolute legend

[@tabithasweeney5402]

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

[@phillipamuseva8674]

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?

[@ayniee1897]

Brilliant video as always

[@AfifaQuadri-g3f]

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

[@Harry-es7zh]

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

[@louisexxxxasasasa2567]

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

[@louisexxxxasasasa2567]

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

[@Nasir-ll6kl]

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

[@AlleryChemistry]

Thanks for letting me know. Will get the ammended on the slides 👍

[@ba5849]

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?

[@fbi8345]

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!

[@AlleryChemistry]

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

[@beyazitdurdu7524]

Does this cover the whole spec for chapter 20

[@tayacarver5077]

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?

Is this for AS year 1 aswell

[@xashley3]

no this is for A2!

[@jacklister962]

Thank you

[@bidishajaman9093]

on 20;31 do u mean strong acids ionise completely and weak acids dont cause seems like u repeated the same sentence twice

[@znn4125]

weak acids partially dissociate
