9:42 how come adding a base when doing the calculations it reacts with the undissociated acid, but when we say why a buffer works, it’s because added base reacts with H+ ions? Is it just because when you add alkali in the questions, there’s a much larger amount of it, and so the reaction it does with the H+ ions is negligible?
It gets always talked about the addition of a strong acid or strong base to a buffer... my question would be how to calculate the ph with the addition of a weak acid? Lets say the addition of acetic acid to a phosphate buffer
I can't lie this was very detailed for a snaprevise video
15:37 - That is the incorrect rearrangement of the Ka equation. It should be H+ = (Ka x HA)/ (A-)
the final outcome is still the same
Actually in my book the equation is represented as [H+] = Ka × [acid]/[salt]... i think the derivation of the equation is not good ..i think
@Lincoln Kastl ive literally seen this exact comment on so many videos 🙄
Definitely a better snap revise video! Although the [H+] eq at 15:35 is rearranged incorrectly
THIS IS SO HARD
This explained it sooo much better than kerboodle, thanks!

Who’s more confused 😭
Me 😢
Thank you so much!!!!

where can i get the presentation
thank you
