Deoxidation. [R.]

A hydrate; a substance containing hydrogen and oxygen, made by combining water with an oxide, and yielding water by elimination. The hydroxides are regarded as compounds of hydroxyl, united usually with basic element or radical; as, calcium hydroxide ethyl hydroxide.

Incapable of being oxidized; as, gold and platinum are inoxidizable in the air.

To prevent or hinder oxidation, rust, or decay; as, inoxidizing oils or varnishes.

An oxide containing one atom of oxygen in each molecule; as, barium monoxide.

A genus of large trilobites characteristic of the primordial formations.

An oxide containing five atoms of oxygen in each molecule; as, phosphorus pentoxide, P2O5.

Act, process, or result of peroxidizing; oxidation to a peroxide.

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

To oxidize to the utmost degree, so as to form a peroxide.

That one of a series of oxides having the lowest proportion of oxygen. See Proto-, 2 (b). protoxide of nitrogen, laughing gas, now called hyponitrous oxideNO. See under Laughing.

To combine with oxygen, as any elementary substance, in such proportion as to form a protoxide.

A tetroxide. [R.]

An oxide containing three atoms of oxygen with two atoms (or radicals) of some other substance; thus, alumina, Al2O3 is a sesquioxide.

An oxide containing a relatively small amount of oxygen, and less than the normal proportion; as, potassium suboxide, K4O.
