Bisulphide :: Bisulphide (n.) A sulphide having two atoms of sulphur in the molecule; a disulphide, as in iron pyrites, FeS2; -- less frequently called bisulphuret..

Bisulphite :: Bisulphite (n.) A salt of sulphurous acid in which the base replaces but half the hydrogen of the acid; an acid sulphite.

Disulphide :: Disulphide (n.) A binary compound of sulphur containing two atoms of sulphur in each molecule; -- formerly called disulphuret. Cf. Bisulphide.

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..

Hydrosulphite :: Hydrosulphite (n.) A saline compound of hydrosulphurous acid and a base.

Hyposulphite :: Hyposulphite (n.) A salt of what was formerly called hyposulphurous acid; a thiosulphate.

Hyposulphite :: Hyposulphite (n.) A salt of hyposulphurous acid proper.

Monosulphide :: Monosulphide (n.) A sulphide containing one atom of sulphur, and analogous to a monoxide; -- contrasted with a polysulphide; as, galena is a monosulphide..

Oxysulphide :: Oxysulphide (n.) A ternary compound of oxygen and sulphur.

Persulphide :: Persulphide (n.) A sulphide containing more sulphur than some other compound of the same elements; as, iron pyrites is a persulphide; -- formerly called persulphuret..

Polysulphide :: Polysulphide (n.) A sulphide having more than one atom of sulphur in the molecule; -- contrasted with monosulphide.

Protosulphide :: Protosulphide (n.) That one of a series of sulphides of any element which has the lowest proportion of sulphur; a sulphide with but one atom of sulphur in the molecule.

Sesquisulphide :: Sesquisulphide (n.) A sulphide, analogous to a sesquioxide, containing three atoms of sulphur to two of the other ingredient; -- formerly called also sesquisulphuret; as, orpiment, As2S3 is arsenic sesquisulphide..

Subsulphide :: Subsulphate (n.) A sulphate with an excess of the base.

Sulphide :: Sulphauric (a.) Of, pertaining to, or designating, a hypothetical sulphacid of gold (aurum), known only in its salts..

Sulphinate :: Sulphide (n.) A binary compound of sulphur, or one so regarded; -- formerly called sulphuret..

Sulphindigotic :: Sulphinate (n.) A salt of a sulphinic acid.

Sulphine :: Sulphindigotic (a.) Of, pertaining to, or designating, a sulphonic acid obtained, as a blue solution, by dissolving indigo in sulphuric acid; -- formerly called also cerulic sulphuric acid, but properly called indigo-disulphonic acid..

Sulphinic :: Sulphine (n.) Any one of a series of basic compounds which consist essentially of sulphur united with hydrocarbon radicals. In general they are oily or crystalline deliquescent substances having a peculiar odor; as, trimethyl sulphine, (CH3)3S.OH. Cf. Sulphonium..

Sulphinide :: Sulphinic (a.) Of, pertaining to, or designating, any one of a series of acids regarded as acid ethereal salts of hyposulphurous acid; as, methyl sulphinic acid, CH3.SO.OH, a thick unstable liquid..

Sulphion :: Sulphinide (n.) A white or yellowish crystalline substance, C6H4.(SO2.CO).NH, produced artificially by the oxidation of a sulphamic derivative of toluene. It is the sweetest substance known, having over two hundred times the sweetening power of sugar, and is known in commerce under the name of saccharine. It has acid properties and forms salts (which are inaccurately called saccharinates)..

Sulphionide :: Sulphion (n.) A hypothetical radical, SO4, regarded as forming the acid or negative constituent of sulphuric acid and the sulphates in electrolytic decomposition; -- so called in accordance with the binary theory of salts..

Sulphite :: Sulphionide (n.) A binary compound of sulphion, or one so regarded; thus, sulphuric acid, H/SO/, is a sulphionide..

Tersulphide :: Tersulphide (n.) A trisulphide.

Trisulphide :: Trisulphide (n.) A sulphide containing three atoms of sulphur.
