Section:

1.(1) Write the balanced solubility equilibrium reaction between PbCl2 solid and its ions in solution.
Be sure to label the phases.

(2) Write the expression of solubility product constant (Ksp) for PbCl2.

(3) Given Ksp = 1.6 x 10 -5 for PbCl2 (MWt=278.10) at 25oC, what is the solubility of PbCl2 in grams/liter?
