Vedclass · Answer

(C) Hydrogen peroxide $(H_2O_2)$ contains oxygen in the $-1$ oxidation state. In chemical reactions,it can either gain electrons (acting as an oxidising agent) to form $H_2O$ (where oxygen is in $-2$ state) or lose electrons (acting as a reducing agent) to form $O_2$ (where oxygen is in $0$ state). Therefore,$H_2O_2$ can act both as an oxidising agent and a reducing agent. For example,in its decomposition: $2H_2O_2^{-1} \rightarrow 2H_2O^{-2} + O_2^0$,it acts as both.
