Hydrogen Peroxide Pure Substance or Mixture
On the identification of hydrogen peroxide as a pure substance or mixture
The universal substance is called hydrogen peroxide, which has unique properties. People often study it to find out whether it is a pure substance or a mixture.
If it is deduced from reason, the pure substance has a single composition, its structure is uniform, and its properties are constant. Hydrogen peroxide has its specific chemical formula $H_2O_2 $, which is composed of hydrogen and oxygen binary elements in a specific ratio. In its molecular structure, two hydrogen atoms and two oxygen atoms are covalently bonded to form a stable structure. This unique composition makes hydrogen peroxide exhibit specific physical and chemical properties under normal conditions, such as colorless liquids, strong oxidation, etc. Therefore, in terms of composition and structure, hydrogen peroxide belongs to the category of pure substances.
However, in reality, commercially available hydrogen peroxide is often not pure. Most exist in the form of aqueous solutions, in which there is a large amount of water in addition to hydrogen peroxide. Water and hydrogen peroxide mix to form a uniform and stable system. The properties of this system are not only affected by hydrogen peroxide, but also related to water. Physical properties such as density and boiling point of the solution are different from pure hydrogen peroxide. In terms of actual existence, hydrogen peroxide in this situation is actually a mixture because it contains two or more substances.
In summary, if hydrogen peroxide is pure, it is considered a pure substance; if it exists in the world in solution form, it is a mixture. To understand its nature, it is necessary to investigate its state to determine whether it is a pure substance or a mixture.
