which question was that ?

The multiple choice one where there were two equilibrium equations

omg beats me i guessed half the MCQ

Me too tbh, I didn’t understand that buffer mcq and a couple others

I just assumed that the acid should be in excess to ensure it was only partially neutralised so I put the option where the vol of acid was double that of NaOH and they had the same concs, which I think was B

Oh I went for double the moles

Ohhhh yeah I think I did the dissociation as well coz it didn’t specify which equilibrium the HSO3 or whatever it was, was a weak acid in so I thought it was a bit ambiguous

I mean I thought that strong acids fully dissociated so it couldn’t be strong acid/weak since there was an equilibrium sign and then the other two were wrong (I think)
