Oxide Ox"ide noun [ French
ox ygène oxygen + ac
ide acid: confer French
oxyde . The French word was correctly spelt
oxide , till about the year 1840, when, in ignorance or forgetfulness of the true history and composition of the word, the orthography was change to make it represent the
υ of Greek
'oxy`s , from which it was supposed to be directly derived.]
(Chemistry) A binary compound of oxygen with an atom or radical, or a compound which is regarded as binary; as, iron oxide , ethyl oxide , nitrogen oxide , etc. » In the chemical nomenclature adopted by Guyton de Morveau, Lavoisier,and their associates, the term
oxides was made to include all compounds of
oxygen which had no acid (F.
acide ) properties, as contrasted with the acids, all of which were at that time supposed to contain oxygen. The orthography
oxyde ,
oxyd , etc., was afterwards introduced in ignorance or disregard of the true etymology, but these forms are now obsolete in English. The spelling
oxid is not common.
Oxidize Ox"i·dize transitive verb [
imperfect & past participle Oxidized ;
present participle & verbal noun Oxidizing .]
(Chemistry) To combine with oxygen, or subject to the action of oxygen, or of an oxidizing agent. Specifically:
(a) To combine with oxygen or with more oxygen; to add oxygen to; as, to oxidize nitrous acid so as to form nitric acid. (b) To remove hydrogen from (anything), as by the action of oxygen; as, to oxidize alcohol so as to form aldehyde. (c) To subject to the action of oxygen or of an oxidizing agent, so as to bring to a higher grade, as an -ous compound to an -ic compound; as, to oxidize mercurous chloride to mercuric chloride. » In certain cases
to oxidize is identical with
to acidify ; for, in nearly all cases, the more oxygen a substance contains the more nearly does it approximate to acid qualities; thus, by oxidation many elements, as sulphur, nitrogen, carbon, chromium, manganese, etc., pass into compounds which are acid anhydrides, and thus practically in the acid state.
