Vedclass · Answer

(D) $H_2O_2$ acts as both an oxidizing and a reducing agent. In the presence of strong oxidizing agents,it acts as a reducing agent. $KMnO_4/H_2SO_4$,$K_2Cr_2O_7/H_2SO_4$,and $Ag_2O$ are strong oxidizing agents and are reduced by $H_2O_2$. $Fe^{3+}$ is the highest oxidation state of iron and cannot be further reduced by $H_2O_2$ to $Fe^{2+}$ under standard conditions; instead,$H_2O_2$ can reduce $Fe^{3+}$ only in specific complex environments,but in general redox chemistry,$Fe^{3+}$ is not reduced by $H_2O_2$.
