What will be solubility of `A_(2)X_(3)` if its solubility product `(K_(sp))` is equal to `1.08 xx 10^(-23)` ?

Options

A. `10^(-5) mol//L`
B. `3.7 xx 10^(-4) mol//L`
C. `1.2 xx 10^(-3) mol//L`
D. `7.5 xx 10^(-4) mol//L`

Answer

A

Explanation

`A_(2)X_(3) hArr 2underset(2s)A^(+3) + 3underset(3s)X^(-2)`
`K_(sp) - (2s)^(2) (3s)^(3)`
`K_(sp) = 108 S^(5)`
`S = ((1.08 xx 10^(-23))/(108))^(1//5) = 10^(-5)mol//L`
