Homework Answers
As the weak acid dissociates partially in aqueous solution,so the concentration of [H3O]+ and [OH]- can't direct calculate from the initial concentration of acid or base.So for determination of pH we should know the value of degree of ionisation and ionisation constant of weak acid.
