Chemical reaction when sulphur dioxide gas is passed through acidified potassium dichromate solution, then the orange colour of potassium dichromate solution changes to green

Answered by admin @ 20/08/2021

Answer:

Explanation:

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.
