Oxygenate :: Oxygenate (v. t.) To unite, or cause to combine, with oxygen; to treat with oxygen; to oxidize; as, oxygenated water (hydrogen dioxide)..

Aeration :: Aeration (n.) A change produced in the blood by exposure to the air in respiration; oxygenation of the blood in respiration; arterialization.

Respiration :: Respiration (n.) The act of resping or breathing; the act of taking in and giving out air; the aggregate of those processes bu which oxygen is introduced into the system, and carbon dioxide, or carbonic acid, removed..

Arterialization :: Arterialization (n.) The process of converting venous blood into arterial blood during its passage through the lungs, oxygen being absorbed and carbonic acid evolved; -- called also aeration and hematosis..

Ozone :: Ozone (n.) A colorless gaseous substance (O/) obtained (as by the silent discharge of electricity in oxygen) as an allotropic form of oxygen, containing three atoms in the molecule. It is a streng oxidizer, and probably exists in the air, though by he ordinary tests it is liable to be confused with certain other substances, as hydrogen dioxide, or certain oxides of nitrogen. It derives its name from its peculiar odor, which resembles that of weak chlorine..

Pentoxide :: Pentoxide (n.) An oxide containing five atoms of oxygen in each molecule; as, phosphorus pentoxide, P2O5..

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..

Alumina :: Alumina (n.) One of the earths, consisting of two parts of aluminium and three of oxygen, Al2O3..

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..

Air :: Air (n.) Any aeriform body; a gas; as, oxygen was formerly called vital air..

Amphigen :: Amphigen (n.) An element that in combination produces amphid salt; -- applied by Berzelius to oxygen, sulphur, selenium, and tellurium..

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

Liquefaction :: Liquefaction (n.) The act, process, or method, of reducing a gas or vapor to a liquid by means of cold or pressure; as, the liquefaction of oxygen or hydrogen..

Bude Light :: Bude light () A light in which high illuminating power is obtained by introducing a jet of oxygen gas or of common air into the center of a flame fed with coal gas or with oil.

Reduce :: Reduce (n.) To bring to the metallic state by separating from impurities; hence, in general, to remove oxygen from; to deoxidize; to combine with, or to subject to the action of, hydrogen; as, ferric iron is reduced to ferrous iron; or metals are reduced from their ores; -- opposed to oxidize..

Sulphamate :: Sulphacid (n.) An acid in which, to a greater or less extent, sulphur plays a part analogous to that of oxygen in an oxyacid; thus, thiosulphuric and sulpharsenic acids are sulphacids; -- called also sulphoacid. See the Note under Acid, n., 2..

Carbohydrate :: Carbohydrate (n.) One of a group of compounds including the sugars, starches, and gums, which contain six (or some multiple of six) carbon atoms, united with a variable number of hydrogen and oxygen atoms, but with the two latter always in proportion as to form water; as dextrose, C6H12O6..

Amylate :: Amylate (n.) A compound of the radical amyl with oxygen and a positive atom or radical.

Metalloid :: Metalloid (n.) Now, one of several elementary substances which in the free state are unlike metals, and whose compounds possess or produce acid, rather than basic, properties; a nonmetal; as, boron, carbon, phosphorus, nitrogen, oxygen, sulphur, chlorine, bromine, etc., are metalloids..

Haemochromogen :: Haemochromogen (n.) A body obtained from hemoglobin, by the action of reducing agents in the absence of oxygen..
