In an acidified aqueous solution of `Mn^(2+), Ni^(2+), Cu^(2+) and hg^(2+)` ions, `H_2S` gas was passed. Precipitates are

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
In acid solution `[S^(2-)]` is low so, `CuS` and `HgS` will precipitate more easilly more due to low `K_(sp)` MnS will precipitate If `H_(2)S` is passed in alkaline solution
