Water and Hydrogen Peroxide Reaction
Whether water reacts with hydrogen peroxide is an important chemical inquiry. Water ($H_ {2} O $) is a common compound in the world, and its properties are stable. Hydrogen peroxide ($H_ {2} O_ {2} $) is oxidizing, but it can slowly decompose at room temperature.
When water meets hydrogen peroxide, in fact, the two do not occur as common chemical reactions, resulting in new compounds. Because of the stable structure of water, the hydrogen-oxygen bond energy is quite high. Although hydrogen peroxide is oxidizing, it is not enough to break the chemical bond of water.
However, from another perspective, hydrogen peroxide can undergo weak ionization in water, and the ionization equation is: $H_ {2} O_ {2}\ rightleftharpoons H ^ {+} + HO_ {2 }^{-}$。 This process can be regarded as the weak interaction between hydrogen peroxide and water, where water acts as a solvent and affects the ionization of hydrogen peroxide.
And because hydrogen peroxide is unstable, it is easy to decompose into water and oxygen. The decomposition equation is: $2H_ {2} O_ {2}\ stackrel {MnO_ {2 }}{=\!=\!=} 2H_ {2} O + O_ {2}\ uparrow $. In this reaction, water is one of the products, but it is not a reaction with water in a strict sense, but the decomposition of hydrogen peroxide itself.
In summary, under normal conditions, there is no typical chemical reaction between water and hydrogen peroxide to form new substances. Only hydrogen peroxide has weak ionization in water, and it is easy to decompose itself to produce water.
