what happens when `SO_2` is passed through acidified `K_2 Cr_2 O_7` solution ?

Text Solution

Verified by Experts

The correct Answer is:
B
`SO_2` turns orange coloured potassium dichromate solution green.
` K_2 Cr_2 O_7 + 4H_2 SO_4 to K_2 SO_4 + Cr_2 SO_4 + Cr_2(SO_4)_3 + 4 H_2 O + 3[O] SO_2 + H_2 O + [O] to H_2 SO_4 ]** 3`
` underset("(orange)")(K_2 Cr_2 O_7) +H_2 SO_4 + 3SO_2 to K_2SO_4 + underset("Green)")(Cr_2 (SO_4)_3)+H_2O`
