What is Hydrogen Peroxide?
Hydrogen peroxide is a clear liquid, slightly more viscous than water. In dilute solution it appears colorless. With its oxidizing properties, hydrogen peroxide is often used as a bleach or cleaning agent. The oxidizing capacity of hydrogen peroxide is so strong that it is considered a highly reactive oxygen species. Hydrogen peroxide is used as a propellant in rocketry. Hydrogen peroxide is naturally produced in organisms as a by-product of oxidative metabolism. Nearly all living things (specifically, all obligate and facultative aerobes) possess enzymes known as catalyse peroxidases, which harmlessly and catalytically decompose low concentrations of hydrogen peroxide to water and oxygen.
