This is a comproportionation reaction. Sulfur dioxide acts as an oxidant; sulfide as a reductant.

#H_2S(aq) + SO_2(aq) rarr 2H_2O + 3S(s) darr#

#"Sulfide ion is oxidized to elemental sulfur"#.

#"Sulfur dioxide is reduced to elemental sulfur"#.

As I recall, the sulfur precipitates from solution as a fine white precipitate.
