Solubility of Salts and the Common Ion Effect • Like the percent ionization of weak acids and bases, the solubility of salts is inﬂuenced by the presence of a common ion.
• The solubility of many salts can be increased by the addition of a species that can form a complex ion with one of the ions (usually the cation) formed when a poorly soluble salt dissolves.
