Hydrogen Peroxide Redox Reaction
Hydrogen peroxide has variable properties and is often involved in redox reactions.
Hydrogen peroxide is oxidizing. In many reactions, it can be used as an oxidizing agent. If ferrous ions ($Fe ^ {2 + }$）， ferrous ions are reductive, the two meet, the valence state of oxygen in hydrogen peroxide decreases, and ferrous ions are oxidized to iron ions ($Fe ^ {3 + }$）。 In this process, hydrogen peroxide exhibits its oxidation power, increasing the valence state of ferrous ions and reducing itself.
Hydrogen peroxide is also reductive. When encountering stronger oxidants, such as acidic potassium permanganate solution ($KMnO_ {4} $under acidic conditions), the manganese element in potassium permanganate is in a high valence state and has strong oxidation. At this time, the valence state of oxygen in hydrogen peroxide increases, and it is oxidized to produce oxygen ($O_ {2} $), which acts as a reducing agent and reduces the valence state of manganese element in potassium permanganate.
The oxidation-reduction reaction of hydrogen peroxide is very important in the field of chemistry. Because it can oxidize other substances and be oxidized by other substances, it has an important role and far-reaching impact in many chemical reaction processes, material preparation and environmental chemistry.
