H+^ + CH3COO-^=CH3COOH1. 1. 0 1pH=pka+log(1÷1) solve to getpH (1)=pkaSimilarly pH2=pka+ log (conj base÷acid) which is also 1;pH2=pka Ratio =1:1 . I think the data of HCl is wrong .It is 0.5moles👍👍👍

First 1 there is no buffer since only HCl gives 1 mole of H+ which gives pH -1. 2nd One there is buffer where pH=pKa as log 1/1 =0. pKa =4.75 as Ka=1.75*10^-5 you get the ration as -2.01
