The reaction 2H2S+SO2→3S+2H2O is

The reaction 2H2S+SO2→3S+2H2O is?

A. not a redox reaction because there is no oxidant in the reaction
B. not a redox reaction because there is no reductant in the reaction
C. a redox reaction in which H2S is the oxidant and SO2 is the reductant
D. a redox reaction in which SO2 is the oxidant and H2S is the reductant

Correct Answer:

Option D – a redox reaction in which SO2 is the oxidant and H2S is the reductant
