$SO_2$ is oxidised to $SO_4^{2-}$. $MnO_4^{-}$ is reduced to $Mn^{2+}$.

Vedclass · Answer

(A) The balanced chemical equation for the reaction between moist $SO_2$ and acidified permanganate solution is: $2MnO_4^{-} + 5SO_2 + 2H_2O \rightarrow 2Mn^{2+} + 5SO_4^{2-} + 4H^{+}$ In this redox reaction,$SO_2$ (where $S$ is in $+4$ oxidation state) is oxidised to $SO_4^{2-}$ (where $S$ is in $+6$ oxidation state). Simultaneously,$MnO_4^{-}$ (where $Mn$ is in $+7$ oxidation state) is reduced to $Mn^{2+}$ (where $Mn$ is in $+2$ oxidation state). Therefore,option $A$ is correct.

In the reaction between moist $SO_2$ and acidified permanganate solution:
