Which metal sulphide is soluble in excess `NH_(3)` solution?

A

ZnS

B

MnS

C

FeS

D

`Cr_(2)S_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
ZnS, MnS, FeS do not dissolve in excess `NH_3` solution due to their low `K_(sp)` values.
`Cr_(2)S_(3)+6NH_(3) hArr [Cr(NH_(3))_(6)]^(3+)+S^(2-)(aq.)`
