Question

so2 and potassium dichromate​

Answer 1

Answer:

This reaction is taken as an experimental verification for the presence of sulphur dioxide gas (SO2).

The equation for the reaction may be stated as follows:-

K2Cr2O7 + H2SO4 + 3SO2 ——— K2SO4 + Cr2(SO4)3 + H2O.

The orange-coloured dichromate solution will turn green due to the formation of chromium(III) sulphate, Cr2(SO4)3.

It is a redox reaction. Here:-

The oxidising agent is potassium dichromate and the reducing agent is sulphur dioxide.
