Hydrogen Peroxide (H2O2) is composed of two hydrogen atoms and two oxygen atoms. H2O2 is a clear liquid, the chemical and colorless, but the extra oxygen molecule makes this additive one natural water from the most powerful oxidizing liquid and able to react explosively with combustible. Used primarily in a diluted water-based solutions. Hydrogen peroxide was found (1818) by LJ Thenard
Although pure hydrogen peroxide is fairly stable, it decomposes into water and oxygen when heated above about 80 � C, but also decompose in the presence of many catalysts, for example, most metals, acids, or organic material is oxidized. A small portion stabilizer is generally acetanilide, is frequently put into it. Being a powerful oxidizer, hydrogen peroxide kills bacteria, viruses and fungi
Hydrogen peroxide has many uses. It is available to households as a water solution of 3% (by weight), but is more used as a mild bleaching agents, medicinally as an antiseptic and laboratory reagents.
Hydrogen peroxide is available for commercial use in some of the concentrations ranging from 27-90%, typically 35%, 50% and 70%.
