H2O2 is the molecular formula of hydrogen peroxide. It is a chemical compound containing hydrogen and oxygen, which decomposes according to the following reaction: 2 H2O2 ? 2 H2O + O2. It is also known as perhydrol or oxydol. Its molar mass is 34.0147 grams per mole.
Hydrogen peroxide is industrially produced from a series of reactions called the anthraquinone process. The simplified equation for this industrial process, excluding any secondary products, reactants and catalysts, is: H2 + O2 ? H2O2. Hydrogen peroxide is available in pharmacies as a water solution with a typical mass percentage of 3 or 6. It is commonly used as a disinfectant in medicine and as a hair bleach agent in cosmetics.
