Let the solubility of an aqueous solution of Mg(OH)2Mg(OH)_{2} be x then its kspk_{sp} is.

A

4x34x^{3}

B

108x5108x^{5}

C

27x427x^{4}

D

9x9x

Answer

4x34x^{3}

Explanation

Solution

Mg(OH)2Mg(OH)_{2}Mg++(X)+2OH(2X)2\underset{(X)}{Mg^{+ +}} + \underset{(2X)^{2}}{2OH^{-}}

Ksp=4X3K_{sp} = 4X^{3}
