H(2)S and SO(2) can be distinguished by:...

`H_(2)S` and `SO_(2)` can be distinguished by:

A

Litmus paper

B

`MnO_(4)^(-)`

C

`(CH_(3)COO)_(2)Pb`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
`H_(2)S,SO_(2)` both are acidic so cannot distinguish by litmus paper.
`MnO_(4)^(-)` oxidising agentt, so both are oxidised to `SO_(4)^(2-)`.
`Pb^(2+)+S^(2-)rarrPbS-("black ppt.")SO_(2)` will not give black precipitate so can be distinguished.
