\(\text{ K}_{a_1} \), \(\text{ K}_{a_2} \) and \(\text{ K}_{a_3} \) are the respective ionization constants for the following reactions (a), (b) and (c).
(a) \( \mathrm{H_2C_2O_4} \rightleftharpoons \mathrm{H^+} + \mathrm{HC_2O_4^-} \)
(b) \( \mathrm{HC_2O_4^-} \rightleftharpoons \mathrm{H^+} + \mathrm{C_2O_4^{2-}} \)
(c) \( \mathrm{H_2C_2O_4} \rightleftharpoons 2\mathrm{H^+} + \mathrm{C_2O_4^{2-}} \)
The relationship between \( K_{a_1} \), \( K_{a_2} \) and \( K_{a_3} \) is given as:
