(i) Solubility product: Solubility product of an -lectrolyte at a specified temperature may be defined as he product of the molar concentrations of ions in a saturated solution, each concentration raised to the power equal to the number of ions produced on lissociation of one molecule of the electrolyte.
(ii) Common ion effect: If a strong electrolyte is added o weak electrolyte having a common ion is added which onizes almost completely, the ionization of the weak lectrolyte is further suppressed. Similarly, if a soluble alt having a common ion is added, if the solution of a paringly soluble salt (like AgCl, etc) the solubility of a -paringly soluble salt further decreases.
