The solubility of insoluble substances can be decreased by the presence of a common ion. AgCl will be our example. AgCl is an ionic substance and, when a tiny bit of it dissolves in solution, it dissociates 100%, into silver ions (Ag) and chloride ions (Cl¯). The lead (II) chloride will become even less soluble - and, of course, the concentration of lead (II) ions in the solution will decrease. Something similar happens whenever you have a sparingly soluble substance. It will be less soluble in a solution which contains any ion which it has in common. This is the common ion effect. Ksp = [Ca 2+ ] [ F –] 2 = 3.9 x 10 -11. By assigning x mol/L as the concentration of CaF 2 dissolved in a saturated solution, we were able to determine the molar solubility of CaF 2 from the Ksp.
