# Solution for What happens when sulphur dioxide is passed through an aqueous solution of Fe(III) salt? - PUC Karnataka Science Class 12 - Chemistry

#### Question

What happens when sulphur dioxide is passed through an aqueous solution of Fe(III) salt?

#### Solution

SO2 acts as a reducing agent when passed through an aqueous solution containing Fe(III) salt. It reduces Fe(III) to Fe(II) i.e., ferric ions to ferrous ions.

2Fe^(3+) + SO_2 + 2H_2O -> 2Fe^(2+) + SO_4^(2-)+4h^(+)

Is there an error in this question or solution?
