Vedclass · Answer

(D) reductant (reducing agent) is a substance that undergoes oxidation itself,meaning the oxidation state of the element (in this case,oxygen in $H_2O_2$) increases.In the reaction $Cl_2 + H_2O_2 	o 2HCl + O_2$,the oxidation state of oxygen in $H_2O_2$ is $-1$,and it increases to $0$ in $O_2$.Therefore,$H_2O_2$ acts as a reducing agent in this reaction.In the other options ($A$,$B$,and $C$),$H_2O_2$ acts as an oxidizing agent because the oxidation state of oxygen decreases from $-1$ to $-2$ (forming $H_2O$).

In which of the following reactions does $H_2O_2$ act as a reductant?
