AQA A-Level Chemistry - Acids, Bases & pH

This video is an introduction to acids, bases and pH. It doesn't cover Kw or how to calculate the pH of a base.

The notes are available here:

you just helped me get my FIRST A* thank you!!

[anisanazir]

I am so glad you're uploading again!!!! I NEED THESE A2 VIDEOS! Thank You!

I genuinely find this educational and comical, its great

[adamjones]

Your videos are amazing!!! I have my CHEM4 mock coming up and i'v been struggling with calculation but these are really helping! Thank you!!

[pathumudara]

Omg i just cant thank you enough... Man.. U just made me pass all my exams.. Thanks dude thanks.... Love ur vids.. They are amazing

[brokke]

thank you for this! you make everything so simple - i have these videos to thank for most of my chemistry grades

[iceshroud]

Just in time for my test tomorrow. cheers man! great channel

[jamesrodrigo]

Good day sir, the videos are fantastc and I honestly can't put into words how much I appreciate them, thank you ever so much!

I have a question, which videos should I be watching If I'm sitting the A2 modules of the old specification? I'm a little confused as these videos aren't labelled old or new spec.

Thanks a tonne hope to see more great content from you! :)

Great video, so happy you're uploading again. Would you be able to divide up the topics as they are on the spec? I know that the topics need to be divided up due to the larger amount of information in each topic, but it would be amazing if you could.

My textbook says that H₂SO₄ is only a strong acid in its first ionisation:
H₂SO₄ --> H⁺ + HSO₄⁻

But for the second ionisation, the HSO₄⁻ ion is a weak acid and is only partially ionised:
HSO₄⁻ <--> H⁺ + SO₄²⁻

So apparently you can't assume that a 0.1 mol dm⁻³ solution of H₂SO₄ = H⁺ concentration of 0.2 mol dm⁻³.

However your video and the rest of the internet says otherwise ;__;

[ramata]

Thank you so much for these videos, they are really helpful. Could you also do one on pH curves, titrations and indicators please

[thfreakin]

Just do pOH
then minus log of that
Then do 14 take that answer to find the ph of a base

[abdallatefnsour]

I really wish thi guy makes more of these explanations

[bilewmbile]

Shouldn't the 2nd example be a -ve pH because when u put it into your calculator it gives a positive answer meaning you need to change it back to a negative
