Solubility product(KSP)

Question

For the electrolyte of type, A₂B , K_sp is given. Then its solubility is calculated by

Easy

A

$\large \frac{{{K_{sp}}}}{4}$
B
C
D

Solution

$\large {A_2}B\left( S \right) \rightleftharpoons \mathop {{A_2}B}\limits_S \left( {aq} \right)\xrightarrow{{}}\mathop {2{A^ + }}\limits_{2S} \left( {aq} \right) + \mathop {{B^{ - 2}}}\limits_S \left( {aq} \right)$
$\large {K_{sp}} = {\left( {2S} \right)^2} \times S = 4{S^3}$
$\large \sqrt[3]{\frac{{{K_{sp}}}}{4}}$
