Oxаlic аcid cаn dоnate twо prоtons to water in successive reactions: (1) H2C2O4(aq) + H2O(l) ⇌ H3O+(aq) + HC2O4-(aq) (2) HC2O4-(aq) + H2O(l) ⇌ H3O+(aq) + C2O42-(aq) If Kc1 = 5.9 × 10-2 and Kc2 = 6.4 × 10-5 at 25°C, what is the value of Kc for reaction (3)? (3) H2C2O4(aq) + 2 H2O(l) ⇌ 2 H3O+(aq) + C2O42-(aq)
