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...

Experiment 8 Solubility of lonic Precipitates Lead chloride is a slightly soluble salt. When lead chloride dissolves in pure water or an aqueous solution, the small quantity that dissolves completely ionizes and reaches equilibrium in a saturated solution, PbCl(s) ® Pb (aq) + 2Cl(aq) Kp = [Pb (C) (1) Lets be the molar solubility of lead chloride. In pure water, s = [Pb ) = (CH) / 2. In a solution containing Cl, a common ion to lead chloride, s...
