Copper(II) carbonate is very poorly soluble in water, but better soluble in NH3(aq) due to the formation of the Cu(NH3)4 2+ complex: CuCO3(s) + 4NH3(aq) ⇄ Cu(NH3)4 2+ (aq) + CO3 2- (aq) CuCO3 (Ksp = 2.3·10-10 ) and the formation constant for Cu(NH3)4 2+ (Kf = 5.0·1012) What was the initial concentration of NH3(aq), if 0.010 mol of CuCO3(s) dissolved at equilibrium in 1.00 L of this solution? [Consider the change in the volume of solution negligible.]
