Solution - What happens when sulphur dioxide is passed through an aqueous solution of Fe(III) salt? - P - Block Group 16 Elements - Oxoacids of Sulphur

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?
