## Answers

pka = 4.74

Ka = 10^ -pka = 10^ -4.74 = 1.8 x 10^ -5

CH3COOH <---> CH3COO- + H+

Ka value is less ( very less than 1) .Ka is indicator of acid strength or acid dissociation. This indicates only small amount of acid ( blue dots) gets dissociated to H+ and CH3COO- ( grey and green). Thus we will have more blue , less green and grey.

First bock ( from left) is proper representation for this equilibirum of acid
