2H2S(g) + SO2(g) → 3S(s) + 2H2O(I). The above reaction is?

  • 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

The correct answer is B. a redox reaction in which SO2 is the oxidant and H2S is the reductant

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.
