Question

Passing $H_{2} S$ gas through following aqueous solution gives sulphide precipitate

Moderate

A

$Z n S O_{4}$
B

$[A g {(N H_{3})}_{2}] C l$
C

$K_{3} [C u {(C N)}_{4}]$
D

$K_{2} [C d {(C N)}_{4}]$

Solution

$Z n S O_{4}$ gives ZnS as precipitate by passing $H_{2} S$ in alkaline condition only $K_{3} [C u {(C N)}_{4}]$ is stable complex that doesn’t give precipitate with $H_{2} S$
