A solution is prepared by dissolving 100.0 mg of CH3COONa in water followed by the addition of 20.0 mL of HCI 0.0300 M. The volume of the solution is then taken to 500.0 mL by further addition of water. Determine whether the addition of 50.0 mg of MgBr2 to the solution would cause precipitation of Mg(OH)2, whose solubility product is 5.61 10-12. Assume that the addition of MgBr2 does not alter the volume. The value of K for CH3COOH is 1.77 10-5.
