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 TH-cam 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
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 👍
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?
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
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
1:01:31 for buffers
life saver
tysm, I was legit looking for this

I was so confused on this topic before I found your video. Thank you so much for creating this online resource !!
You're welcome!
youre a life saver! I'm roughly a month off my exams now and I'm really feeling the pressure now.
im less than 24 hours away from my exam and i am really feeling the pressure now
@@aleenhussain5990 did u pass cuz?
@@isabdel3975 not him but i binge watched them all the night before and came out with an A
Thanks for the quality content that you provide for free.
My pleasure!

A week away from exams - thank you, the video has helped a lot!
what did you get! how did you revise?
I LOVE YOU SO MUCH THANK YOU FOR HELPING ME FINALLY UNDERSTAND
You're welcome 😊
Appreciate your hard work!
My pleasure!
Thank you so so much for these videos! They're so helpful! :)
You're so welcome!

Thanks! You're very welcome 😀
did you get the a* then
my teacher didn't even teach the PH changes ... thanks for these videos
thank you sir you absolute legend
33:28 equation should read [H+] = 2[Acid]
Brilliant video as always
I’m doing CCEA such a great help!! Thanks
thanks
You're welcome
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?
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+]
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?
Thank you🙏
You’re welcome 😊
Hi Sir, I think there is a mistake on the acids and bases slide it should say weak acids dissociate poorly instead of strong. 🙂
Thanks for letting me know. Will get the ammended on the slides 👍

At 17:25 you say that BH+ is the conjugate acid because it’s a proton donor? Did you mean to say proton acceptor?
Thank you so much!!!
the best videos !
GREAT VID THANKS
Amazing , thanks sir
How can we know whether an acid or base completely ionizes or not?
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
Thanks Sir.
At the end on the uses of buffer bit, does the carbonic acid dissociate differently for the 2 different reactions?
So helpful thank you!!!!! :)
You're so welcome!
Goat, thank you
Does this cover the whole spec for chapter 20
Thank you
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
no this is for A2!
on 20;31 do u mean strong acids ionise completely and weak acids dont cause seems like u repeated the same sentence twice
weak acids partially dissociate
