Hydrolysis constant of salt formed by neutralisation of strong base with weak acid is given as w h a K K K Thus, h a 1 K K ; Higher is ak lower will be hydrolysis and hence less basic will be solution as a 1 pH 7 pK log c 2 Thus, pH of sodium salt NaB formed from HB+NaOH will be lower than pH of solution of NaA of same concentration. As, a a K HA K HB Thus, of NaA > of NaB h h K K Hence, pH of NaA will have higher pH.
