Question

(D) Let the solubility of all salts be $s$. For $M_2X$: $M_2X \rightleftharpoons 2M^+ + X^{2-}$. $K_{sp} = (2s)^2(s) = 4s^3$. For $QY_2$: $QY_2 \right

$K_{sp}(M_2X) = K_{sp}(QY_2) = K_{sp}(PZ_2)$

Vedclass · Answer

(D) Let the solubility of all salts be $s$. For $M_2X$: $M_2X \rightleftharpoons 2M^+ + X^{2-}$. $K_{sp} = (2s)^2(s) = 4s^3$. For $QY_2$: $QY_2 \rightleftharpoons Q^{2+} + 2Y^-$. $K_{sp} = (s)(2s)^2 = 4s^3$. For $PZ_2$: $PZ_2 \rightleftharpoons P^{2+} + 2Z^-$. $K_{sp} = (s)(2s)^2 = 4s^3$. Since all salts have the same solubility $s$,their $K_{sp}$ values are equal: $K_{sp}(M_2X) = K_{sp}(QY_2) = K_{sp}(PZ_2)$.

If the solubility of salts $M_2X$,$QY_2$,and $PZ_2$ is the same,what is the relationship between their $K_{sp}$ values?
