The act of combining with hydrogen, or the state of being so combined.
a.
Capable of neutralizing four molecules of a monacid base; having four hydrogen atoms capable of replacement by bases; quadribasic; -- said of certain acids; thus, normal silicic acid, Si(OH)4, is a tetrabasic acid.
p. pr. & vb. n.
of Hydrogenize
imp. & p. p.
of Hydrogenate
n.
A glyceride formed by the replacement of three hydrogen atoms in glycerin by acid radicals.
v. t.
To hydrogenize.
v. t.
To combine with hydrogen; to treat with, or subject to the action of, hydrogen; to reduce; -- contrasted with oxidize.
n.
Hydrogen; -- called also in view of its supposed metallic nature.
a.
Capable of neutralizing four molecules of a monobasic acid; having four hydrogen atoms capable of replacement ba acids or acid atoms; -- said of certain bases; thus, erythrine, C4H6(OH)4, is a tetracid alcohol.
imp. & p. p.
of Hydrogenize
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.
a.
Of, pertaining to, or designating, hydrogen telluride, which is regarded as an acid, especially when in solution.
a.
Having a valence of three; capable of being combined with, substituted for, or compared with, three atoms of hydrogen; -- said of triad atoms or radicals; thus, nitrogen is trivalent in ammonia.
a.
Capable of neutralizing three molecules of a monobasic acid or the equivalent; having three hydrogen atoms which may be acid radicals; -- said of certain bases; thus, glycerin is a triacid base.
p. pr. & vb. n.
of Hydrogenate
n.
A double fluoride of zirconium and hydrogen, or some other positive element or radical; as, zircofluoride of sodium.
a.
Capable of neutralizing three molecules of a monacid base, or their equivalent; having three hydrogen atoms capable of replacement by basic elements on radicals; -- said of certain acids; thus, citric acid is a tribasic acid.
