In case of weak acid Hx H x H C For every weak acid, a K C Thus, a H K C x . This line means that the hydrogen ion concentration of the weak acids depends on the value of ionization constant and the concentration both. Thus, the reason is true. So, if we assume HA HB 1M Then, 3 HA H 10 1 x and 4 HB H 10 Hence, 2 HA 2 HB H 3.16 10 H 10 x Thus, pH of HA = 1.50 pH= HB = 2
