Vedclass · Answer

(A) For a sparingly soluble salt $A_pB_q$,the dissociation reaction is: $A_pB_q(s) \rightleftharpoons pA^{q+}(aq) + qB^{p-}(aq)$ If the solubility of the salt is $S$,then the concentration of $A^{q+}$ is $pS$ and the concentration of $B^{p-}$ is $qS$. The solubility product expression is: $K_{sp} = [A^{q+}]^p [B^{p-}]^q$ Substituting the concentrations: $K_{sp} = (pS)^p (qS)^q$ $K_{sp} = p^p S^p q^q S^q$ $K_{sp} = p^p q^q S^{p+q}$

For a sparingly soluble salt $A_pB_q$,what is the relationship between its solubility $(S)$ and solubility product $(K_{sp})$?
