If solubility product of $Z r_{3} {(P O_{4})}_{4}$ is denoted by $K_{s p}$ and its molar solubility is denoted by $S$ , then which of the following relation between $S$ and $K_{s p}$ is correct?

Options:

Answer:

Solution:

$Z r_{3} {(P O_{4})}_{4} (s) ⇌ \underset{3 s}{3 Z r^{+ 4}} (a q) + 4 \underset{4 s}{P O_{4}^{3 -}} (a q)$
$K_{s p} = {[Z r^{+ 4}]}^{3} {[P O_{4}^{3 -}]}^{4}$
$= {(3 s)}^{3} {(4 s)}^{4}$
$K_{s p} = 6912 S^{7}$
$s = {(K_{s p} / 6912)}^{\frac{1}{7}}$
