Answer to Question #70550 in Chemistry for Evan

Question

Consider the following system in equilibrium:
CuCO3 (s) ⇌ Cu2+ (aq) + CO32-(aq) Ksp = 1.4 x10-10
CO2 (g) ⇌ CO2 (aq) K1 = 3.4 x10-2
CO2 (aq) + H2O (l) ⇌ HCO3-(aq) + H+(aq) K2 = 4.7 x10-7
HCO3-(aq) ⇌ CO32-(aq) + H+(aq) K3 = 5.1 x10-11
At equilibrium, the pH of the solution is equal to 5.745 when the system is
saturated with CuCO3. In standard conditions (pressure of 1 bar), calculate how
many grams of copper are contained in 1.54 L of water (assume density is 1
kg/L).
