When polluted air is scrubbed with `H_(2)SO_(4)` solution,

A

`CH_(4)` is oxidized to `CO_(2)`

B

`H_(2)S` is oxidized to sulphur

C

Oxides of nitrogen and sulphur are oxidised

D

`NO` is reduced to `N_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
when polluted air is scrubbed with `H_(2)SO_(4)`
`SO_(2)` is oxidized to `H_(2)SO_(4)`
`SO_(2)+H_(2)O+O overset(H_(2)SO_(4))(rarr)H_(2)SO_(4)`
`NO_(2)` is oxidized to `HNO_(3)`
`NO_(2)+H_(2)O+O overset(H_(2)SO_(4))(rarr) HNO_(3)`.
