Question

Which from the following equations represents the relation between solubility ( $\text{mol L}^{-1}$ ) and solubility product for the salt $\text{B}_2\text{A}$ ?

• A. $\text{S} = \left( \frac{\text{K}_{\text{sp}}}{4} \right)^{1/3}$
• B. $\text{S} = (4 \text{K}_{\text{sp}})^{1/3}$
• C. $\text{S} = \left( \frac{\text{K}_{\text{sp}}}{3} \right)^{1/3}$
• D. $\text{S} = (3 \text{K}_{\text{sp}})^{1/3}$

Hint:

Shortcut: For $A_xB_y$: $K_{sp} = x^x y^y S^{x+y}$
