Passing `H_(2)S` gas into a mixture of `Mn^(2+), Ni^(2+), Cu^(2+)` and `Hg^(2+)` ions in an acidified aqueous solution precipitates

A

CuS and HgS

B

MnS and CuS

C

MnS and NiS

D

NiS and HgS

Text Solution

Verified by Experts

The correct Answer is:
A
(a) In the acidic medium, only the cations of group (II) is mixture analysis i.e. `Cu^(2+)(aq)" and "Hg^(2+)(aq)` ions are precipitated as their respective sulphides. These are CuS and HgS (both black in colour).
