An oxide containing more oxygen than some other oxide of the same element. Formerly peroxides were regarded as the highest oxides. Cf. Per-, 2.

Literally, a compound that is rich in oxygen. Used to describe compounds that formally contain the O22- ion.

a viscous liquid with strong oxidizing properties; a powerful bleaching agent; also used as a disinfectant and (in strong concentrations) as an oxidant in rocket fuels

an inorganic compound containing the divalent ion -O-O-

bleach with peroxide; "She must peroxide her hair-it looks unnaturally blond"

a compound that has an oxygen-oxygen bond

(see Hydrogen Peroxide).

hydrogen peroxide; a compound containing oxygen that yields hydrogen peroxide with an acid.

Peroxides are a group of compounds that contain the O2- ion. It is used to initiate the polymerization for high-pressure free radical polymerization processes.

An oxide in which contains two oxygen atoms joined to each other.

Any compound containing the two oxygen atoms united together into a bivalent– O-O group. Readily releases abnormally active atomic oxygen, and therefore any peroxide is a strong oxidizer. Examples are hydrogen peroxide and potassium peroxymonosulfate

Any one of several strong oxidizing compounds, but generally hydrogen peroxide.

A compound containing oxygen in the -1 oxidation state. Metal peroxides contain the peroxide ion, O22

Chemicals which contain two oxygen atoms bound together. Often explosive.
