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 UA-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!
Thanks for the quality content that you provide for free.
My pleasure!
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
A week away from exams - thank you, the video has helped a lot!

Thanks! You're very welcome 😀
did you get the a* then
I LOVE YOU SO MUCH THANK YOU FOR HELPING ME FINALLY UNDERSTAND
You're welcome 😊
my teacher didn't even teach the PH changes ... thanks for these videos
thank you sir you absolute legend
Appreciate your hard work!
My pleasure!
Thank you so so much for these videos! They're so helpful! :)
You're so welcome!
I’m doing CCEA such a great help!! Thanks
Brilliant video as always
33:28 equation should read [H+] = 2[Acid]
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?
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+]
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 👍
thanks
You're welcome

GREAT VID THANKS
Amazing , thanks sir
Thank you so much!!!
How can we know whether an acid or base completely ionizes or not?
At 17:25 you say that BH+ is the conjugate acid because it’s a proton donor? Did you mean to say proton acceptor?
At the end on the uses of buffer bit, does the carbonic acid dissociate differently for the 2 different reactions?
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?
Goat, thank you
Thanks Sir.
So helpful thank you!!!!! :)
You're so welcome!
Does this cover the whole spec for chapter 20
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?
Thank you
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
Is this for AS year 1 aswell
no this is for A2!
