Determine the change in the oxidation number of S in H_2S and SO_2 in the following industrial reaction: 2H_2S(g)+SO_2(g) to 3S (g) + 2H_2 O (g)

Determine the change in the oxidation number of S in H_2S and SO_2 in

1.	Determine the change in the oxidation number of S in H_2S and SO_2 in the following industrial reaction: 2H_2S(g)+SO_2(g) to 3S (g) + 2H_2 O (g)
Answer» Solution :OXIDATION NUMBER of S changes from -2 in `H_2S` and +4 in `SO_2` to zero in ELEMENTAL sulphur.
