Vedclass · Answer

(A) The dissociation of the salt $MX_4$ is represented as: $MX_{4(s)} ightleftharpoons M_{(aq)}^{4+} + 4X_{(aq)}^{-}$ If the solubility of the salt is $S$,then the concentration of $M^{4+}$ is $S$ and the concentration of $X^{-}$ is $4S$. The solubility product constant $K_{sp}$ is given by the product of the concentrations of the ions raised to their stoichiometric coefficients: $K_{sp} = [M^{4+}][X^{-}]^4$ Substituting the values: $K_{sp} = (S)(4S)^4$ $K_{sp} = S 	imes 256S^4$ $K_{sp} = 256S^5$
