Given the following reactions

CuO (s) ⇌ Cu2+ (aq) + O2– (aq) K1

O2- (aq) + H2O (l) ⇌ 2OH– (aq) K2

H2O (l) ⇌ H+ (aq) + OH– (aq) Kw

Write the mass action expression for CuO dissolving in acid and express the value of the equilibrium constant in terms of K1, K2 and Kw.

CuO (s) + 2H+ (aq) ⇌ Cu2+ (aq) + H2O (l)
