For the reaction MgF2(s) <=> Mg2+(aq) + 2 F-(aq), at a given temperature, K = 7.4 x 10-11. What MASS (you’ll need to calculate molarity!) of MgF2 could be added to 2L of water, such that ALL the MgF2 dissolves? How soluble is MgF2 in water (qualitative answer…ie, VERY, NOT VERY, etc).

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.]

2. The equilibrium constant for the following reaction is called the "solubility product" of calcium fluoride: CaF2(s) - Cal(aq) + 2F-(ay) K = Kp = 3.2 x 10-11 (a) Write an expression for the equilibrium constant of this reaction in terms of concentrations. Why do you suppose we call this a solubility product instead of a solubility quotient or ratio? (b) Calculate the equilibrium concentrations of Ca2+ and F if excess solid CaF is placed in water.
