1. (Chem.) A colorless, tasteless, odorless, gaseous element occurring in the free state in the atmosphere,
of which it forms about 23 per cent by weight and about 21 per cent by volume, being slightly heavier
than nitrogen. Symbol O. Atomic weight 15.96.
It occurs combined in immense quantities, forming eight ninths by weight of water, and probably one
half by weight of the entire solid crust of the globe, being an ingredient of silica, the silicates, sulphates,
carbonates, nitrates, etc. Oxygen combines with all elements forming oxides, bases, oxyacid anhydrides,
etc., the process in general being called oxidation, of which combustion is only an intense modification.
At ordinary temperatures with most substances it is moderately active, but at higher temperatures it is
one of the most violent and powerful chemical agents known. It is indispensable in respiration, and in
general is the most universally active and efficient element. It may be prepared in the pure state by
heating potassium chlorate.
This element (called dephlogisticated air by Priestley) was named oxygen by Lavoisier because he
supposed it to be a constituent of all acids. This is not so in the case of a very few acids (as hydrochloric,
hydrobromic, hydric sulphide, etc.), but these do contain elements analogous to oxygen in property and
action. Moreover, the fact that most elements approach the nearer to acid qualities in proportion as
they are combined with more oxygen, shows the great accuracy and breadth of Lavoisier's conception
of its nature.
2. Chlorine used in bleaching. [Manufacturing name]
Oxygenate
(Ox"y*gen*ate) v. t. [imp. & p. p. Oxygenated ; p. pr. & vb. n. Oxygenating ] [Cf. F.
oxygéner.] (Chem.) To unite, or cause to combine, with oxygen; to treat with oxygen; to oxidize; as, oxygenated
water
