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.
Types of peroxides, from top to bottom: peroxide ion, organic peroxide, organic hydroperoxide, peracid. 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 industrial peroxides are produced using hydrogen peroxide. Reactions with aldehydes and ketones yield a series of compounds depending on conditions. Specific reactions include addition of hydrogen peroxide across the C=O double bond: R 2 C=O + H 2 O 2 → R 2 C(OH)OOH. In some cases, these hydroperoxides convert to give cyclic diperoxides:
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.
The recommended method would be to name it sodium sulfate—water(1/10). Similarly other examples of lattice compounds are: CaCl 2 ·8NH 3, calcium chloride— ammonia (1/8) 2Na 2 CO 3 ·3H 2 O 2, sodium carbonate—hydrogen peroxide (2/3) AlCl 3 ·4EtOH, aluminium chloride—ethanol (1/4)
It is prepared by the reaction of hydrogen peroxide with nitrite: [4] H 2 O 2 + NO − 2 → ONOO − + H 2 O. Its presence is indicated by the absorbance at 302 nm (pH 12, ε 302 = 1670 M −1 cm −1).
Fenton's reagent is a solution of hydrogen peroxide (H 2 O 2) and an iron catalyst (typically iron(II) sulfate, FeSO 4). [1] It is used to oxidize contaminants or waste water as part of an advanced oxidation process.
HOF is an intermediate in the oxidation of water by fluorine, which produces hydrogen fluoride, oxygen difluoride, hydrogen peroxide, ozone and oxygen. HOF is explosive at room temperature, forming HF and O 2: [1] 2 HOF → 2 HF + O 2. This reaction is catalyzed by water. [2]
