What is the correct representation for the solubility product of `SnS_(2)` ?

Options

A. `[Sn^(2+)][S^(2-)]^(2)`
B. `[Sn^(4+)][S^(2-)]^(2)`
C. `[Sn^(2+)][2S^(2-)]`
D. `[Sn^(4+)][2S^(2-)]^(2)`

Answer

B

Explanation

The solubility equilibrium of `SnS_(2) ` is
`SnS_(2) hArr Sn^(4+)+2S^(2-)`
Solubility product `K_(sp)=[Sn^(4+)][S^(2-)]^(2)`
