The ionic product of an electrolyte in its saturated solution

Vedclass · Answer

(A) Solubility product $(K_{sp})$ refers to the product of the molar concentrations of the ions present in a saturated solution of a sparingly soluble ionic compound,each raised to the power of its stoichiometric coefficient.For a general salt $A_{a}B_{b(s)} \rightleftharpoons aA_{(aq)}^{b+} + bB_{(aq)}^{a-}$,The equilibrium constant is $K_{c} = \frac{[A^{b+}]^a [B^{a-}]^b}{[A_{a}B_{b}]}$.Since the concentration of the pure solid $[A_{a}B_{b}]$ is constant,the solubility product constant is defined as $K_{sp} = [A^{b+}]^a [B^{a-}]^b$.Thus,it is the product of the ionic concentrations in a saturated solution.
