Name the gas that can readily decolourise acidified `KMnO_(4)` solution:

A

`SO_(2)`

B

`NO_(2)`

C

`P_(2) O_(5)`

D

`CO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`SO_(2)` is readily decolourises acidified `KMnO_(4)`
`2Kunderset((O.A))overset(+7)(MnO_(4)) + 5underset((R.A))overset(+4)(SO_(2)) + 2H_(2)O rarr underset("Colourless")(2MnSO_(4)) + 2H_(2)SO_(4) + K_(2)SO_(4)`
