Hydrogen peroxide and ammonia
The molecular formula of hydrogen peroxide is H2O2, and the electron image is H-O-O-H. In this molecule, H is eleven and oxygen is the image. Among them, valence oxygen is unstable, both oxidizing and reducing.
Physical properties of hydrogen peroxide:Colorless viscous liquid, its aqueous solution is commonly known as hydrogen peroxide.
The chemical properties of hydrogen peroxide
instability
When exposed to light or heat, H2O2 decomposes:
Manganese dioxide catalyzes the decomposition of H2O2;
Hydrogen peroxide can be decomposed to produce O2, which has a strong oxidation effect and can dilute organic colors, so it has bleaching properties.
Strong oxidizing property
When H2O2 encounters a reducing agent, it exhibits oxidizing properties. such as
weak reducibility
When H2O2 encounters strong oxidants, it exhibits reducing properties. Such as H2O2 as a reducing agent, its oxide is O2.
very weak acid
The use of hydrogen peroxide
Use 3-point diluted hydrogen peroxide as a disinfectant.
The industry uses 10-point hydrogen peroxide as a bleaching agent.
H2O2 can be used as rocket fuel.
Whether H2O2 is used as an oxidant or a reducing agent, it will not add impurity particles to the solution.
Cleaning effect:
HN3 H2O2:
SC-1:nh4oh : H2O 2: H2O=1:1:5 ~ 1:23:7
SC-1 is an alkaline solution of H2O2 and NH4OH. Through the strong oxidation of H2O2 and the dissolution of NH4OH, the organic pollutants become water-soluble compounds, which are removed by washing with deionized water.
