<unk>  is a chemical compound with the formula<unk> . In its pure form it is a colorless liquid, slightly more viscous than water; however, for safety reasons it is normally used as an aqueous solution.<unk>  is the simplest peroxide (a compound with an oxygen-oxygen single bond) and finds use as a strong oxidizer, bleaching agent and disinfectant. Concentrated<unk> , or 'high-test peroxide,' is a reactive oxygen species and has been used as a propellant in rocketry.<unk>  is often described as being “water but with one more oxygen atom” a description which can give the incorrect impression that there is a great deal of similarity between the two compounds. Pure<unk>  will explode if heated to boiling, will cause serious contact burns to the skin and can set materials alight on contact. For these reasons it is usually handled as a dilute solution (household grades are typically 3-6%). Its chemistry is dominated by the nature of its unstable peroxide bond.
