Which of the following metal sulphides has maximum solubility in water?

A

`CdS(K_(sp)=36xx10^(-30))`

B

`FeS(K_(sp)=11xx10^(20))`

C

`HgS(K_(sp)=32xx10^(-54))`

D

`ZnS(K_(sp)=11xx10^(-22))`

Text Solution

Verified by Experts

The correct Answer is:
B

The salt with highest `K_(sp)` is most soluble. Thus, FeS will be most soluble.
