SOLVED: Recall the effect of pH on the solubility of CaCO3 that we discussed in class. The equations involved are Equation (1): CaCO3 (s) ⇌ Ca2 (aq) CO3^2-(aq) Equation (2): CO2^2-(aq) H3O (aq) ⇌ HCO3^-(aq) H2O (CaCO3 has Ksp = 4.96 x 10^-9, HCO2 has Ka1 = 4.45 x 10^-7 and Ka2 = 4.7 x 10^-17)(a) Calculate the equilibrium constant (K) for Equation (2).(b) Calculate the equilibrium constant (K) for the following reaction: CaCO3 (s) H2O(aq) ⇌ Ca2 (aq) HCO3^-(aq) H2OAnswer:(c) The
