Oxiodic :: Oxiodic (a.) Pertaining to, or designating, certain compounds of iodine and oxygen..

Mercaptan :: Mercaptan (n.) Any one of series of compounds, hydrosulphides of alcohol radicals, in composition resembling the alcohols, but containing sulphur in place of oxygen, and hence called also the sulphur alcohols. In general, they are colorless liquids having a strong, repulsive, garlic odor. The name is specifically applied to ethyl mercaptan, C2H5SH. So called from its avidity for mercury, and other metals..

Deutoxide :: Deutoxide (n.) A compound containing in the molecule two atoms of oxygen united with some other element or radical; -- usually called dioxide, or less frequently, binoxide..

Periodic :: Periodic (a.) Pertaining to, derived from, or designating, the highest oxygen acid (HIO/) of iodine..

Acetone :: Acetone (n.) A volatile liquid consisting of three parts of carbon, six of hydrogen, and one of oxygen; pyroacetic spirit, -- obtained by the distillation of certain acetates, or by the destructive distillation of citric acid, starch, sugar, or gum, with quicklime..

Element :: Element (n.) One of the ultimate, undecomposable constituents of any kind of matter. Specifically: (Chem.) A substance which cannot be decomposed into different kinds of matter by any means at present employed; as, the elements of water are oxygen and hydrogen..

Sulphydric :: Sulphydrate (n.) A compound, analogous to a hydrate, regarded as a salt of sulphydric acid, or as a derivative of hydrogen sulphide in which one half of the hydrogen is replaced by a base (as potassium sulphydrate, KSH), or as a hydrate in which the oxygen has been wholly or partially replaced by sulphur..

Carboxyl :: Carboxyl (n.) The complex radical, CO.OH, regarded as the essential and characteristic constituent which all oxygen acids of carbon (as formic, acetic, benzoic acids, etc.) have in common; -- called also oxatyl..

Bisilicate :: Bisilicate (n.) A salt of metasilicic acid; -- so called because the ratio of the oxygen of the silica to the oxygen of the base is as two to one. The bisilicates include many of the most common and important minerals.

Disoxygenate :: Disoxygenate (v. t.) To deprive of oxygen; to deoxidize.

Microcrith :: Microcrith (n.) The weight of the half hydrogen molecule, or of the hydrogen atom, taken as the standard in comparing the atomic weights of the elements; thus, an atom of oxygen weighs sixteen microcriths. See Crith..

Nonoxygenous :: Nonoxygenous (a.) Without oxygen; characterized by the absence of oxygen; as, a nonoxygenous alkaloid..

Hydrate :: Hydrate (n.) A substance which does not contain water as such, but has its constituents (hydrogen, oxygen, hydroxyl) so arranged that water may be eliminated; hence, a derivative of, or compound with, hydroxyl; hydroxide; as, ethyl hydrate, or common alcohol; calcium hydrate, or slaked lime..

Oxymuriatic :: Oxymuriatic (a.) Pertaining to, or consisting of, oxygen and muriatic acid, that is, hydrochloric acid..

Arterialize :: Arterialize (v. t.) To transform, as the venous blood, into arterial blood by exposure to oxygen in the lungs; to make arterial..

Protoxide :: Protoxide (n.) That one of a series of oxides having the lowest proportion of oxygen. See Proto-, 2 (b)..

Oxyhydrogen :: Oxyhydrogen (a.) Of or pertaining to a mixture of oxygen and hydrogen; as, oxyhydrogen gas..

Protoxidize :: Protoxidize (v. t.) To combine with oxygen, as any elementary substance, in such proportion as to form a protoxide..

Bond :: Bond (n.) A unit of chemical attraction; as, oxygen has two bonds of affinity. It is often represented in graphic formulae by a short line or dash. See Diagram of Benzene nucleus, and Valence..

Gas :: Gas (n.) An aeriform fluid; -- a term used at first by chemists as synonymous with air, but since restricted to fluids supposed to be permanently elastic, as oxygen, hydrogen, etc., in distinction from vapors, as steam, which become liquid on a reduction of temperature. In present usage, since all of the supposed permanent gases have been liquified by cold and pressure, the term has resumed nearly its original signification, and is applied to any substance in the elastic or aeriform state..
