The solubility of `Sb_(2)S_(3)` in water is `1.0 xx 10^(-5) ` mol/letre at 298K. What will be its solubility product ?

Options

A. `108 xx 10^(-25)`
B. `1.0 xx 10^(-25)`
C. `144 xx 10^(-25)`
D. `126 xx 10^(-24)`

Answer

A

Explanation

`{:(Sb_(2) rarr,2Sb^(+2)+,3S^(-),,K_(sp) = (2x)^(2).(3x)^(3),),(,2x,3x,,):}`
`K_(sp) = 108x^(5), K_(sp) = 108 xx (1 xx 10^(-5))^(5) = 108 xx 10^(-25)`.
