Question: The correct representation for solubility product of \(SnS_{2}\)is ....

The correct representation for solubility product of SnS2SnS_{2}is .

A

3×10−2M3 \times 10^{- 2}M

B

[Sn2+][S2−]2\lbrack Sn^{2 +}\rbrack\lbrack S^{2 -}\rbrack^{2}

C

[Sn2+][2S2−]\lbrack Sn^{2 +}\rbrack\lbrack 2S^{2 -}\rbrack

D

[Sn4+][2S2−]2\lbrack Sn^{4 +}\rbrack\lbrack 2S^{2 -}\rbrack^{2}

Answer

3×10−2M3 \times 10^{- 2}M

Explanation

Solution

SnS2SnS_{2} ⇌ Sn4++2S2−Sn^{4 +} + 2S^{2 -}

∴Ksp=[Sn4+][S2−]2\therefore K_{sp} = \lbrack Sn^{4 +}\rbrack\lbrack S^{2 -}\rbrack^{2}
