Vedclass · Answer

(A) reducing agent is a substance that undergoes oxidation,meaning its oxidation state increases. In $H_2O_2$,the oxidation state of oxygen is $-1$. When it acts as a reducing agent,it is oxidized to $O_2$ (where the oxidation state of oxygen is $0$).In reaction $(A)$: $PbO_{2(s)} + H_2O_{2(aq)} 	o PbO_{(s)} + H_2O_{(l)} + O_{2(g)}$,the oxidation state of oxygen in $H_2O_2$ changes from $-1$ to $0$. Thus,$H_2O_2$ acts as a reducing agent.

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