A. a redox reaction H2S is the oxidant and SO2 is the reductant B. a redox reaction in which SO2 is the oxidant and H2S is the reductant C. not a redox reaction because there is no oxidant in reaction equation D. not a redox because there is no reductant in the reaction equation
Correct Answer: B
Explanation
In the above reaction, H\(_2\)S is oxidized to H\(_2\)O while SO\(_2\) is reduced to S. Hence, H\(_2\)S is the reductant while SO\(_2\) is the oxidant.
