Solubility product(KSP)

Question

$solubility product of salt {MX}_{4} is K_{SP}$ and solubility S mol/L are related as

Easy

A

$S = {[K_{SP} / 256]}^{1 / 5}$
B

$S = {[128 K_{SP}]}^{1 / 4}$
C

$S = {[256 K_{SP}]}^{1 / 5}$
D

$S = {[K_{SP} / 128]}^{1 / 4}$

Solution

${MX}_{4} ⇌ M^{4 +} + 4 X^{-}$
S 4S
$K_{SP} = [M^{4 +}] [X^{-}] = S \times {(4 S)}^{4} = 256 S^{5}$
