The correct representation for solubility product of Sn S_2 is - Vidyadip

MCQ

The correct representation for solubility product of $Sn{S_2}$ is

✓
$[S{n^{4 + }}]\,\,{[{S^{2 - }}]^2}$
B
$[S{n^{2 + }}]\,\,{[{S^{2 - }}]^2}$
C
$[S{n^{2 + }}]\,\,[2{S^{2 - }}]$
D
$[S{n^{4 + }}]\,\,{[2{S^{2 - }}]^2}$

✓

Answer

Correct option: A.

$[S{n^{4 + }}]\,\,{[{S^{2 - }}]^2}$

(a) $Sn{S_2} ⇌ S{n^{4 + }} + 2{S^{2 - }}$

$\therefore \,{K_{sp}} = [S{n^{4 + }}]\,\,{[{S^{2 - }}]^2}$
