Wow, these revision videos are AMAZING, thank you so much!👌👌 Also, could you make such videos on the following topics as well: -Functional Groups of Organic Chemistry -Titration Curves and Calculations -Entropy and Gibbs free energy

[@samirakarimi2267]

for the OCR exam do you have to know about choosing the right component for the buffer solution based on the pka?

[@MaChemGuy]

Not mentioned specifically in the syllabus but the understanding around this has been tested

[@hootsgoobs4795]

my teacher said that we should be saying that the alkali/base reacts with the CH3COOH instead of H+ so im not sure which one to use any guidance would be appreciated

[@MaChemGuy]

Hoots Goobs It’s the H+ Think about the definition of a base, it’s a proton acceptor

[@hootsgoobs4795]

MaChemGuy I thought so too it’s just my teacher said on the new spec we are supposed to write that it reacts with the HA because there is too little of H+ I think for my exam I’ll write both Since both points do turn up in mark schemes from old spec Thanks for helping me understand it better

Hi Sir, have u done the exam qs on blood ph and buffers in 2019 Paper 1 Q17 in your walkthroughs? If you have can u plz link the video cause I cant seem to find it in your walkthrough playlist. Ty

[@MaChemGuy]

I’ll have a look, if not, I’ll do it!
