OH
n.
A white crystalline substance, C6H4(OH)2, obtained by the reduction of quinone. It is a diacid phenol, resembling, and metameric with, pyrocatechin and resorcin. Called also dihydroxy benzene.
a.
Of or pertaining to a sulphamide; derived from, or related to, a sulphamide; specifically, designating an amido acid derivative, NH2.SO2.OH, of sulphuric acid (analogous to sulphonic acid) which is not known in the free state, but is known in its salts.
a.
Yielding supplies of any kind; serving to form or make up, a greater object of the same kind, as a part, branch, etc.; contributing; as, the Ohio has many tributary streams, and is itself tributary to the Mississippi.
n. pl.
A tribe of North American Indians who occupied Western New York and part of Ohio, but were driven away and widely dispersed by the Iroquois.
n.
A phenol derivative of cymene, C10H13.OH, isomeric with carvacrol, found in oil of thyme, and extracted as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties; -- called also hydroxy cymene.
a.
Pertaining to, or derived from, a sulphone; -- used specifically to designate any one of a series of acids (regarded as acid ethereal salts of sulphurous acid) obtained by the oxidation of the mercaptans, or by treating sulphuric acid with certain aromatic bases (as benzene); as, phenyl sulphonic acid, C6H5.SO2.OH, a stable colorless crystalline substance.
a.
[OE. seer, AS. sear (assumed) fr. searian to wither; akin to D. zoor dry, LG. soor, OHG. sor/n to to wither, Gr. a"y`ein to parch, to dry, Skr. /ush (for sush) to dry, to wither, Zend hush to dry. Ã152. Cf. Austere, Sorrel, a.] Dry; withered; no longer green; -- applied to leaves.
a.
Pertaining to, or designating, a yellow crystalline astringent acid, (NO2)3.C6H.(OH)2, obtained by the action of nitric acid on resorcin. Styphnic acid resembles picric acid, but is not bitter. It acts like a strong dibasic acid, having a series of well defined salts.
n.
A colorless crystalline substance, C6H3.CH3.(OH)2, which is obtained from certain lichens (Roccella, Lecanora, etc.), also from extract of aloes, and artificially from certain derivatives of toluene. It changes readily into orcein.
n.
One of the larger measures of electrical resistance, amounting to one million ohms.
n.
The standard unit in the measure of electrical resistance, being the resistance of a circuit in which a potential difference of one volt produces a current of one ampere. As defined by the International Electrical Congress in 1893, and by United States Statute, it is a resistance substantially equal to 109 units of resistance of the C.G.S. system of electro-magnetic units, and is represented by the resistance offered to an unvarying electric current by a column of mercury at the temperature of melting ice 14.4521 grams in mass, of a constant cross-sectional area, and of the length of 106.3 centimeters. As thus defined it is called the international ohm.
n.
A nitrogenous, organic base, NH2.OH, resembling ammonia, and produced by a modified reduction of nitric acid. It is usually obtained as a volatile, unstable solution in water. It acts as a strong reducing agent.
n.
Ohe who tosser.
n.
Any one of six metameric phenol derivatives of xylene, obtained as crystalline substances, (CH3)2.C6H3.OH.
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.
interj.
An exclamation of surprise, etc.
n.
The unit of electro-motive force; -- defined by the International Electrical Congress in 1893 and by United States Statute as, that electro-motive force which steadily applied to a conductor whose resistance is one ohm will produce a current of one ampere. It is practically equivalent to / the electro-motive force of a standard Clark's cell at a temperature of 15¡ C.
n.
A ganoid fish of the Sturgeon family (Scaphirhynchus platyrhynchus) of the Mississippi and Ohio rivers; -- called also white sturgeon.
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.
