Hydrogen peroxide is a chemical substance with the chemical formula H2O2. It is a compound composed of two elements, hydrogen and oxygen, so it is impure. Hydrogen peroxide usually exists in the form of aqueous solution, which contains a certain proportion of hydrogen peroxide molecules. In practical application, hydrogen peroxide can be used in disinfection, bleaching, water treatment, medical treatment and other fields.
Although hydrogen peroxide itself is not pure, it has certain purity standards. Hydrogen peroxide produced in industry is usually classified according to different concentrations, such as 3%, 6% and 9%, which respectively represent the mass percentage of hydrogen peroxide in the solution. It should be noted that hydrogen peroxide is a strong oxidant, which is corrosive and irritating. When using or contacting hydrogen peroxide, you should abide by relevant safety operation procedures and pay attention to protective measures to avoid harm to human body and environment.
