Calculating Solubility from Ksp

The Ksp for CaF2 is 3.9 x 10-11 at 25 °C. Assuming equilibrium is established between solid and dissolved CaF2, and that there are no other important equilibria affecting its solubility, calculate the solubility of CaF2 in grams per liter.

Of the five salts listed below, which has the highest concentration of its cation in water? Assume that all salt solutions are saturated and that the ions do not undergo any additional reactions in water.

(a) lead (II) chromate, Ksp = 2.3 x 10-13, (b) cobalt(ll) hydroxide, Ksp = 1.3 x 10-15, (c) cobalt(ll) sulfide, Ksp = 5 x 10-22, (d) chromium(lll) hydroxide, Ksp = 1.6 x 10-30, (e) silver sulfide, Ksp = 6 x 10-51
