What Is Hydrogen Peroxide?
Hydrogen peroxide is a chemical compound made up of hydrogen and oxygen atoms. It is a pale blue liquid in its pure form, although it appears colorless in dilute aqueous solutions. Its chemical formula is H₂O₂, and it is structurally similar to water, but it contains one additional oxygen atom. Hydrogen peroxide is relatively unstable and can decompose into water and oxygen under certain conditions.
as matter of fact Hydrogen peroxide was first identified in 1818 by French chemist Louis Jacques Thénard, who produced it by reacting barium peroxide with nitric acid. Since its discovery, improvements in manufacturing and stabilization techniques have made it possible to produce hydrogen peroxide at different concentrations and levels of purity.
