2H2S(g) + SO2(g) → 3S(s) + 2H2O(I). The above reaction is?
- a redox reaction H2S is the oxidant and SO2 is the reductant
-
a redox reaction in which SO2 is the oxidant and H2S is the reductant
- not a redox reaction because there is no oxidant in reaction equation
- not a redox because there is no reductant in the reaction equation
The correct answer is: 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.
