Consider the dissolution equation of lead(II) chloride.
PbCl2 (s) ⇆ Pb2+ (aq) + 2Cl− (aq)
Suppose you add 0.2307 g of PbCl2 (s) to 50.0 mL of water. In the resulting saturated solution, you find that the concentration of Pb2+ (aq) is 0.0159 M and the concentration of Cl− (aq) is 0.0318 M.
What is the value of the equilibrium constant, Ksp, for the dissolution of PbCl2?
