Hydroxyl :: Hydroxyl (n.) A compound radical, or unsaturated group, HO, consisting of one atom of hydrogen and one of oxygen. It is a characteristic part of the hydrates, the alcohols, the oxygen acids, etc..

Monoxide :: Monoxide (n.) An oxide containing one atom of oxygen in each molecule; as, barium monoxide..

Oxy- :: Oxy- () A compound containing oxygen.

Dioxide :: Dioxide (n.) An oxide containing two atoms of oxygen in each molecule; binoxide.

Trioxide :: Trioxide (n.) An oxide containing three atoms of oxygen; as, sulphur trioxide, SO3; -- formerly called tritoxide..

Unisilicate :: Unisilicate (n.) A salt of orthosilicic acid, H4SiO4; -- so called because the ratio of the oxygen atoms united to the basic metals and silicon respectively is 1:1; for example, Mg2SiO4 or 2MgO.SiO2..

Hydroxide :: Hydroxide (n.) 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..

Deoxygenize :: Deoxygenize (v. t.) To deoxidize.

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

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..

Deoxygenation :: Deoxygenation (n.) The act or operation of depriving of oxygen.

Determination :: Determination (n.) The act, process, or result of any accurate measurement, as of length, volume, weight, intensity, etc.; as, the determination of the ohm or of the wave length of light; the determination of the salt in sea water, or the oxygen in the air..

Sulphocarbonate :: Sulphoarsenic (a.) Of, pertaining to, or containing, sulphur and arsenic; -- said of an acid which is the same as arsenic acid with the substitution of sulphur for oxygen..

Deoxidize :: Deoxidize (v. t.) To deprive of oxygen; to reduce from the state of an oxide.

Burn :: Burn (v. t.) To cause to combine with oxygen or other active agent, with evolution of heat; to consume; to oxidize; as, a man burns a certain amount of carbon at each respiration; to burn iron in oxygen..

Anaerobies :: Anaerobies (n. pl.) Microorganisms which do not require oxygen, but are killed by it..

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

Acetyl :: Acetyl (n.) A complex, hypothetical radical, composed of two parts of carbon to three of hydrogen and one of oxygen. Its hydroxide is acetic acid..

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

Valence :: Valence (n.) The degree of combining power of an atom (or radical) as shown by the number of atoms of hydrogen (or of other monads, as chlorine, sodium, etc.) with which it will combine, or for which it can be substituted, or with which it can be compared; thus, an atom of hydrogen is a monad, and has a valence of one; the atoms of oxygen, nitrogen, and carbon are respectively dyads, triads, and tetrads, and have a valence respectively of two, three, and four..
