How does the acidified permanganate solution react with
`SO_(2)`
Write the ionic equations for the reactions.

Explanation

Reactions of `KMnO_(4)` in acidic medium
`MnO_(4)^(-)+8H^(+)+5e^(-)rarr Mn^(2+)+4H_(2)O`
`SO_(2)` : It is oxidised to `SO_(4)^(2-)` by acidified `KMnO_(4)`
`SO_(2)+2H_(2)O rarr SO_(4)^(2-)+4H^(+)+2e^(-)`
From equation (i) and (ii)
`5SO_(2)+2MnO_(4)^(-) rarr 2Mn^(2+)+4H^(+)+5SO_(4)^(2-)`
