Monamine :: Monamine (n.) A basic compound containing one amido group; as, methyl amine is a monamine..

Boride :: Boride (n.) A binary compound of boron with a more positive or basic element or radical; -- formerly called boruret.

Monobasic :: Monobasic (a.) Capable of being neutralized by a univalent base or basic radical; having but one acid hydrogen atom to be replaced; -- said of acids; as, acetic, nitric, and hydrochloric acids are monobasic..

Negative :: Negative (a.) Metalloidal; nonmetallic; -- contracted with positive or basic; as, the nitro group is negative..

Dibasic :: Dibasic (a.) Having two acid hydrogen atoms capable of replacement by basic atoms or radicals, in forming salts; bibasic; -- said of acids, as oxalic or sulphuric acids. Cf. Diacid, Bibasic..

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

Quadribasic :: Quadribasic (a.) Same as Tetrabasic.

Tetrabasic :: Tetrabasic (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..

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..

Monsel''s Salt :: Monsel's salt () A basic sulphate of iron; -- so named from Monsel, a Frenchman..

Hydrosulphide :: Hydrosulphide (n.) One of a series of compounds, 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..

Basic :: Basic (a.) Having the base in excess, or the amount of the base atomically greater than that of the acid, or exceeding in proportion that of the related neutral salt..

Metaphosphoric :: Metaphosphoric (a.) Pertaining to, or designating, a monobasic acid, HPO3, analogous to nitric acid, and, by heating phosphoric acid, obtained as a crystalline substance, commonly called glacial phosphoric acid..

Amine :: Amine (n.) One of a class of strongly basic substances derived from ammonia by replacement of one or more hydrogen atoms by a basic atom or radical.

Nonacid :: Nonacid (a.) Destitute of acid properties; hence, basic; metallic; positive; -- said of certain atoms and radicals..

Imide :: Imide (n.) A compound with, or derivative of, the imido group; specif., a compound of one or more acid radicals with the imido group, or with a monamine; hence, also, 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..

Bibasic :: Bibasic (a.) Having to hydrogen atoms which can be replaced by positive or basic atoms or radicals to form salts; -- said of acids. See Dibasic.

Antimonate :: Antimonate (n.) A compound of antimonic acid with a base or basic radical.

Styptic :: Styphnic (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..

Electro-negative :: Electro-negative (a.) Negative; nonmetallic; acid; -- opposed to positive, metallic, or basic..
