Vedclass · Answer

(C) The dissociation of the salt $AB_2$ is given by: $AB_2(s) ightleftharpoons A^{2+}(aq) + 2B^-(aq)$.Let the solubility be $s = 1.0 	imes 10^{-5} \ mol \ L^{-1}$.The solubility product $K_{sp}$ is defined as: $K_{sp} = [A^{2+}][B^-]^2$.Substituting the concentrations in terms of $s$: $K_{sp} = (s)(2s)^2 = 4s^3$.Now,substitute the value of $s$: $K_{sp} = 4 	imes (1.0 	imes 10^{-5})^3$.$K_{sp} = 4 	imes 10^{-15}$.

The solubility of a sparingly soluble salt $AB_2$ in water is $1.0 \times 10^{-5} \ mol \ L^{-1}$. Its solubility product is .......?
