Ca(OH)₂ has a K_sp of 6.5 X 10^-6

(a) If 0.370 g of Ca(OH)₂ is added to 500 mL of water and the mixture is allowed to come to equilibrium,will the solution be saturated?

(b) If 50 mL of the solution from part (a) is added to each of the beakers shown here, in which beakers, if any,will a precipitate form? In those cases where a precipitate forms, what is its identity?
