peroxide

(pərŏk`sīd), chemical compound containing two oxygen atoms, each of which is bonded to the other and to a radical or some element other than oxygen; e.g., in hydrogen peroxidehydrogen peroxide,
chemical compound, H2O2, a colorless, syrupy liquid that is a strong oxidizing agent and, in water solution, a weak acid. It is miscible with cold water and is soluble in alcohol and ether.

, H2O2, the atoms are joined together in the chainlike structure H-O-O-H. Peroxides are powerful oxidizing agents. They are unstable, releasing oxygen when heated. Peroxides may be formed directly by reaction of an element or compound with oxygen. In dry, carbon-dioxide-free air, sodium or barium metal reacts to form its peroxide. In moist air, zinc metal is oxidized and hydrogen peroxide is formed. When a metal peroxide is treated with a dilute acid, a solution of hydrogen peroxide and a metal salt is formed. Ethersether,
any of a number of organic compounds whose molecules contain two hydrocarbon groups joined by single bonds to an oxygen atom. The most common of these compounds is ethyl ether, CH3CH2OCH2CH3

 can react with oxygen from the air to form peroxides. This creates a special hazard, since the peroxides are often so unstable that they decompose explosively if heated.

Peroxide

 

any of a class of compounds in which atoms of oxygen are bonded to each other as well as to atoms of a more electropositive element. Examples are hydrogen peroxide (H—O—O—H) and barium peroxide

The term “peroxide” was adopted by the international chemical nomenclature; in the Russian nomenclature the word for peroxide is perekis’.

peroxide

1. short for hydrogen peroxide esp when used for bleaching hair
2. any of a class of metallic oxides, such as sodium peroxide, Na2O2, that contain the divalent ion --O-O--
3. any of certain dioxides, such as manganese peroxide, MnO2, that resemble peroxides in their formula but do not contain the --O-O-- ion
4. any of a class of organic compounds whose molecules contain two oxygen atoms bound together. They tend to be explosive
