The Effect of a Common Ion on Molar Solubility: pH and
OH- as a Common Ion
We have seen from our study of acid/base chemistry that the
presence of a weak base such as ammonia (Kb = 1.8 X
10-5) can affect the pH of an aqueous solution. This pH
can in turn affect the solubility of a metal hydroxide salt as a
result of the common ion effect. The Ksp for manganese (II)
hydroxide = 2.0 X 10-13. What...

The solubility-product constant for Zn(OH)2 is Ksp=3.00×10−16. The formation constant for the hydroxo complex, Zn(OH)42−, is Kf=4.60×1017. A solubility-product constant, Ksp, corresponds to a reaction with the following general format: salt(s)⇌cation(aq)+anion(aq) A formation constant, Kf, corresponds to a reaction with the following general format: metal ion(aq)+Lewis base(aq)⇌complex ion(aq) Part A When Zn(OH)2(s) was added to 1.00 L of a basic solution, 1.11×10−2 mol of the solid dissolved.
