Vedclass · Answer

(D) $H_2O_2$ (Hydrogen peroxide) is a versatile chemical compound. $1$. It acts as an oxidising agent in both acidic and basic media (e.g.,$2Fe^{2+} + H_2O_2 ightarrow 2Fe^{3+} + 2OH^-$). $2$. It acts as a reducing agent in the presence of stronger oxidising agents (e.g.,$2MnO_4^- + 6H^+ + 5H_2O_2 ightarrow 2Mn^{2+} + 8H_2O + 5O_2$). $3$. $H_2O_2$ is a very weak acid,even weaker than water $(K_a \approx 1.5 	imes 10^{-12})$,and it forms hydroperoxides with bases. $4$. It does not exhibit basic properties. Therefore,the statement that $H_2O_2$ has basic properties is incorrect.
