Ferric sulphocyanate(Chem.), a dark red crystalline substance usually obtained in a blood-red solution, and recognized as a test for ferric iron.

(Sul`pho*cy*an"ic) a. [See Sulphur, Cyanic.] (Chem.) Of, pertaining to, derived from, or designating, a sulphacid, HSCN, analogous to cyanic acid, and obtained as a colorless deliquescent crystalline substance, having a bitter saline taste, and not poisonous.

(Sul`pho*cy"a*nide) n. (Chem.) See Sulphocyanate.

(Sul`pho*cy*an"o*gen) n. (Chem.) See Persulphocyanogen. [Obs.]

Sulphinate to Sum

(Sul"phi*nate) n. (Chem.) A salt of a sulphinic acid.

(Sulph*in`di*got"ic) a. (Chem.) 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.

(Sul"phine) n. (Chem.) 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.

(Sul*phin"ic) a. (Chem.) 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.

(Sul"phi*nide) n. [Sulpho- + amine + anhydride.] (Chem.) A white or yellowish crystalline substance, C6H4.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). I. Remsen.

(Sul"phi*on) n. [Sulpho- + ion.] (Chem.) 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. [Written also sulphione.]

(Sulph*i"on*ide) n. (Chem.) A binary compound of sulphion, or one so regarded; thus, sulphuric acid, HSO is a sulphionide.

(Sul"phite) n. [Cf. F. sulfite. See Sulphur.] (Chem.) A salt of sulphurous acid.

(Sul"pho-) (Chem.) A prefix (also used adjectively) designating sulphur as an ingredient in certain compounds. Cf. Thio-.

(Sul`pho*ar*sen"ic) a. (Chem.) Of, pertaining to, or containing, sulphur and arsenic; — said of an acid which is the same as arsenic acid with the substitution of sulphur for oxygen.

(Sul`pho*car"bon*ate) n. (Chem.) A salt of sulphocarbonic acid; a thiocarbonate.

(Sul`pho*car*bon"ic) a. (Chem.) Of, pertaining to, or designating, a sulphacid, H2CSO2 (called also thiocarbonic acid), or an acid, H2CS3, analogous to carbonic acid, obtained as a yellow oily liquid of a pungent odor, and forming salts.

(Sul`pho*cy"a*nate) n. (Chem.) A salt of sulphocyanic acid; — also called thiocyanate, and formerly inaccurately sulphocyanide.
