Hydrogen peroxide (H2O2) Reactions and Chemical Properties
Hydrogen peroxide can behave as an oxidizing agent and reducing agent. So, hydrogen peroxide can react with many compounds. Hydrogen peroxide is oxidized to oxygen by strong oxidizing agents such as acidic KMnO 4 or K 2 CrO 4 or K Cr 2 O 7. Silver oxide is reduced to silver by hydrogen peroxide. Fe 2+ ions are oxidized to Fe 3+ ions.
