A white, crystalline, nitrogenous body closely related to creatin but more basic in its properties, formed from the latter by the action of acids, and occurring naturally in muscle tissue and in urine. [Written also kretinine.]

A basic, dark-colored, holocrystalline, igneous rock, consisting essentially of a triclinic feldspar and pyroxene with magnetic iron; -- often limited to rocks pretertiary in age. It includes part of what was early called greenstone.

ent; -- said of a base or radical as capable of saturating two acid monad radicals or a dibasic acid. Cf. Dibasic, a., and Biacid.

A compound containing two amido groups united with one or more basic or positive radicals, -- as contrasted with a diamide.

A dark-colored, basic, igneous rock, composed essentially of pyroxene and a triclinic feldspar with magnetic iron. By many authors it is considered equivalent to a coarse-grained basalt.

e refraction. (Opt.) See Refraction. -- Double salt. (Chem.) (a) A mixed salt of any polybasic acid which has been saturated by different bases or basic radicals, as the double carbonate of sodium and potassium, NaKCO3.6H2O. (b) A molecular combination of two distinct salts, as common alum, which consists of the sulph…

Negative; nonmetallic; acid; -- opposed to positive, metallic, or basic.

Hence: Positive; metallic; basic; -- distinguished from negative, nonmetallic, or acid.

oom, and under the name phycite obtained from the alga Protococcus vulgaris. It is a tetrabasic alcohol, corresponding to glycol and glycerin.

A double fluoride of silicon and some other (usually basic) element or radical, regarded as a salt of fluosilicic acid; -- called also silicofluoride.

e of copper. -- Chrome green. See under Chrome. -- Emerald green. (Chem.) (a) A complex basic derivative of aniline produced as a metallic, green crystalline substance, and used for dyeing silk, wool, and mordanted vegetable fiber a brilliant green; - - called also aldehyde green, acid green, malachite green, Victori…

A prefix or combining form, used to denote six, sixth, etc.; as, hexatomic, hexabasic.

unds, derived from hydrogen sulphide by the replacement of half its hydrogen by a base or basic radical; as, potassium hydrosulphide, KSH. The hydrosulphides are analogous to the hydrates and include the mercaptans.

by elimination. The hydroxides are regarded as compounds of hydroxyl, united usually with basic element or radical; as, calcium hydroxide ethyl hydroxide.

o, a derivative of ammonia, in which two atoms of hydrogen have been replaced by divalent basic or acid radicals; -- frequently used as a combining form; as, succinimide.

A suffix, indicating that those substances of whose names it is a part are basic, and alkaloidal in their nature.

se compounds in which it has a relatively high valence; as, iodic acid. Iodic acid, a monobasic acid, consisting of iodine with three parts of oxygen and one of hydrogen.

alba Etym: [L.] (Med. Chem.), a bulky white amorphous substance, consisting of a hydrous basic carbonate of magnesium, and used as a mild cathartic.

An elementary substance, as sodium, calcium, or copper, whose oxide or hydroxide has basic rather than acid properties, as contrasted with the nonmetals, or metalloids. No sharp line can be drawn between the metals and nonmetals, and certain elements partake of both acid and basic qualities, as chromium, manganese, bis…

essential and implied properties of a metal, as contrasted with a nonmetal or metalloid; basic; antacid; positive. Metallic iron, iron in the state of the metal, as distinquished from its ores, as magnetic iron. -- Metallic paper, paper covered with a thin solution of lime, whiting, and size. When written upon with a…
