`H_(2)S` will precipitate the sulphide of all the metals from the solution of chlorides of `Cu,Zn` and Cd if:

A

The solution is aqueous

B

The solution is acidic

C

The solution is dilute acidic

D

Any of these solutions is present

Text Solution

Verified by Experts

The correct Answer is:
C
Due to common ion effect as
`HCl to H^(+) + Cl^(-) , H_(2)S to 2H^(+) + S^(2-)`
