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...
