@RR. Hmm I have not seen a hydrolysis question with a dibasic acid ...
Is the answer 1.656 ?

Test paper in coaching

I simply did it like a monobasic acid. Cause the difference in ka1 and ka2 is a factor of 10^4.
@RR. Which one? 👀
RR.
RR.
Ahaguru
@Wolgwang Did u get the answer if u do it that way?

Nope I got 1.656 which is wrong.
@RR. Can you please share the solution when you get?
RR.
RR.
Ahhh... Okay... So, this is the solution they have given
But, I didn't understand it

Do you know any such formula?

@RR. I had applied $[H+]=\sqrt{\dfrac{K_w K_{a_2}}{K_b}}$
@RR. Let me see if I can derive it.

What is the most acidic proton in butanone? The one at C1 or the one at C3, and why?
Wolgwang

@RaphaelJ.F.Berger I think C1
Cause of less +Inductive effect.
RR.
RR.
@RaphaelJ.F.Berger C1 cause C3 would be sp2 hybridised and C1 sp3 hybridised. So, getting rid of H in C1 would be easier and hence more acidic

Yes, also what I thought! thanks. ChatGPT claims the contrary ...
