The solubility of a sparingly soluble `A_(2)B` salt at a given temperature being x(M), its solubility product is-

Options

A. `x^(3)`
B. `2x^(2)`
C. `4x^(3)`
D. `2x^(3)`

Explanation

`A_(2)B(g)hArr underset(2x(M))(2A^(+)(aq))+underset(x(M))(B^(2-)(aq))`
`K_(sp)=[A^(+)]^(2)[B^(2-)]=(2x)^(2)x=4x^(3)`.
