Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
The peroxide group is marked in blue. R, R 1 and R 2 mark hydrocarbon moieties. The most common peroxide is hydrogen peroxide (H 2 O 2), colloquially known simply as "peroxide". It is marketed as solutions in water at various concentrations. Many organic peroxides are known as well. In addition to hydrogen peroxide, some other major classes of ...
Together with its conjugate base superoxide, hydroperoxyl is an important reactive oxygen species.Unlike • O − 2, which has reducing properties, HO • 2 can act as an oxidant in a number of biologically important reactions, such as the abstraction of hydrogen atoms from tocopherol and polyunstaturated fatty acids in the lipid bilayer.
For the preparation of the complex, urea is dissolved in 30% hydrogen peroxide (molar ratio 2:3) at temperatures below 60 °C. upon cooling this solution, hydrogen peroxide–urea precipitates in the form of small platelets. [2] Akin to water of crystallization, hydrogen peroxide cocrystallizes with urea with the stoichiometry of 1:1.
Sodium percarbonate or sodium carbonate peroxide is a chemical substance with empirical formula Na 2 H 3 CO 6.It is an adduct of sodium carbonate ("soda ash" or "washing soda") and hydrogen peroxide (that is, a perhydrate) whose formula is more properly written as 2 Na 2 CO 3 · 3 H 2 O 2.

Calcium peroxide or calcium dioxide is the inorganic compound with the formula CaO 2. It is the peroxide (O 2 2− ) salt of Ca 2+ . Commercial samples can be yellowish, but the pure compound is white.
Hydrogen peroxide (H 2 O 2) is a common disinfectant and readily decomposes to form water and oxygen. Trioxidane (H 2 O 3 ) is rare and readily decomposes into water and singlet oxygen . Tetraoxidane (H 2 O 4 ) has been synthesized by reaction among peroxy radicals at low temperature.
