Mixing Hydrogen Peroxide and Ammonia Reactions
On the reaction of hydrogen peroxide mixed with ammonia water
Smell hydrogen oxidize hydrogen dioxide, which has strong oxidation; ammonia water, ammonia dissolved in water, containing hydroxide, showing the nature of weak bases. If the two are mixed, the change in the reaction can be investigated.
When the two meet, the first response is the decomposition of hydrogen peroxide. Hydrogen peroxide is inherently unstable, and it is divided into water and oxygen at room temperature or in a catalytic environment. The existence of ammonia can be catalyzed by weak bases to promote this division. The corresponding formula is as follows:\ (2H_ {2} O_ {2}\ stackrel {NH_ {3}\ cdot H_ {2} O} {\ longrightarrow} 2H_ {2} O + O_ {2}\ uparrow\).
Furthermore, ammonia has the property of reduction, while hydrogen peroxide has the ability of strong oxidation, and the two may play a role in oxidation reduction. Nitrogen in ammonia is\ (-3\) valent and can be oxidized by hydrogen peroxide. Or products such as nitrogen generation, dinitrogen monoxide, and nitrate, depending on the ratio of the two and the corresponding article. If the amount of ammonia is sufficient and the amount of hydrogen peroxide is appropriate, or the following should be:\ (2NH_ {3} + 3H_ {2} O_ {2}\ longrightarrow N_ {2} + 6H_ {2} O\). In this should, the nitrogen of ammonia is oxidized, and the oxygen of hydrogen peroxide is reduced.
If the amount of hydrogen peroxide is large, ammonia may be oxidized to a higher valence state. If nitrate is formed, it should be:\ (NH_ {3} + 7H_ {2} O_ {2}\ longrightarrow NO_ {3} ^ {-} + 9H_ {2} O + H ^{+}\) 。 This process is complex and involves multiple steps, and various intermediates may be formed in the middle.
And when mixing, it is often accompanied by heat release. Because the above reactions are mostly exothermic, especially redox, heat release is particularly obvious. This heat can cause the temperature of the system to rise, but also promote the speed of reaction, or cause more severe reaction.
In addition, after mixing, the properties of the product also change greatly. If the generated nitrogen escapes in the air, the increase of oxygen makes the oxidation of the system stronger. If nitrate is formed, the acidity and alkalinity of the solution are also changed, or acidic, because hydrogen ions are generated.
In summary, hydrogen peroxide is mixed with ammonia water, and the synthesis should be complicated, the products are diverse, and often accompanied by thermal changes. In practice, it is necessary to be careful, to know the principle of its application in detail, and to control its rules, in order to prevent the emergence of dangerous situations, and also to study its application. It is used in chemical industry, scientific research, etc.
