Hydrogen Peroxide (H2O2) is made up of two hydrogen atoms and two oxygen atoms. H2O2 is clear liquid, chemical compound and colorless, but that extra oxygen molecule makes this natural water additive one of the most powerful oxidizers liquid and capable of reacting explosively with combustibles. Used mostly in diluted water based solutions . Hydrogen peroxide was discovered (1818) by L. J. Thenard
Although pure hydrogen peroxide is fairly stable, it decomposes into water and oxygen when heated above about 80°C; it also decomposes in the presence of numerous catalysts, e.g., most metals, acids, or oxidizable organic materials. A small amount of stabilizer, usually acetanilide, is often added to it. Being a powerful oxidizer, hydrogen peroxide kills bacteria, viruses and fungi
Hydrogen peroxide has many uses. It is available for household use as a 3% (by weight) water solution; it is used as a mild bleaching agent, medicinally as an antiseptic and a laboratory reagent.
Hydrogen peroxide is available for commercial use in several concentrations ranging from 27 - 90 %, usually 35%, 50% and 70%.
