Question

write the equation for the reaction of so2 on ferric salt​

Answer 1

Answer:

So2 means sulphur dioxide

And it is very harmful for the environment.

Answer 2

Answer:

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.

2Fe3+ + SO2 + 2H2O → 2Fe2+ + SO42- + 4H+
