(a) Calculate the pH of a solution obtained by mixing 50.00 mL of 0.20 M weak acid HA ($K_a = 10^{-5}$) and 50.00 mL of 0.20 M NaOH at room temperature.
(b)One mole of a salt of type MX is dissolved in 1.00 kg of water. The freezing point of the solution is −2.4°C. Calculate the percent dissociation of the salt in water. (IIT JAM 2007)
