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 peroxide hydrogen 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.

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. Ethers ether, 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

peroxide

Any of a class of chemical compounds in which two oxygen atoms are linked by a single covalent bond. Several organic (see organic compound) and inorganic (see inorganic compound) peroxides are useful as bleaching and oxidizing agents (see oxidation-reduction), as initiators of polymerization reactions, and in the preparation of hydrogen peroxide (a mild bleach and antiseptic) and other oxygen compounds. The peroxide anion (chemical formula O₂²⁻) is present in peroxides of inorganic compounds.
