Hydrosulphuric :: Hydrosulphuric (a.) Pertaining to, or derived from, hydrogen and sulphur; as, hydrosulphuric acid, a designation applied to the solution of hydrogen sulphide in water..

Taurine :: Taurine (n.) A body occurring in small quantity in the juices of muscle, in the lungs, and elsewhere, but especially in the bile, where it is found as a component part of taurocholic acid, from which it can be prepared by decomposition of the acid. It crystallizes in colorless, regular six-sided prisms, and is especially characterized by containing both nitrogen and sulphur, being chemically amido-isethionic acid, C2H7NSO3..

Normal :: Normal (a.) Denoting certain hypothetical compounds, as acids from which the real acids are obtained by dehydration; thus, normal sulphuric acid and normal nitric acid are respectively S(OH)6, and N(OH)5..

Ustulation :: Ustulation (n.) The operation of expelling one substance from another by heat, as sulphur or arsenic from ores, in a muffle..

Hexad :: Hexad (n.) An atom whose valence is six, and which can be theoretically combined with, substituted for, or replaced by, six monad atoms or radicals; as, sulphur is a hexad in sulphuric acid. Also used as an adjective..

Sulphurous :: Sulphurize (v. t.) To combine or impregnate with sulphur or any of its compounds; as, to sulphurize caoutchouc in vulcanizing..

Test :: Test (n.) A reaction employed to recognize or distinguish any particular substance or constituent of a compound, as the production of some characteristic precipitate; also, the reagent employed to produce such reaction; thus, the ordinary test for sulphuric acid is the production of a white insoluble precipitate of barium sulphate by means of some soluble barium salt..

Sacchulmic :: Sacchulmic (a.) Of, pertaining to, or designating, an acid obtained as a dark amorphous substance by the long-continued boiling of sucrose with very dilute sulphuric acid. It resembles humic acid..

Disulphuret :: Disulphuret (n.) See Disulphide.

Hydrosulphureted :: Hydrosulphureted (a.) Combined with hydrogen sulphide.

Keratin :: Keratin (n.) A nitrogenous substance, or mixture of substances, containing sulphur in a loose state of combination, and forming the chemical basis of epidermal tissues, such as horn, hair, feathers, and the like. It is an insoluble substance, and, unlike elastin, is not dissolved even by gastric or pancreatic juice. By decomposition with sulphuric acid it yields leucin and tyrosin, as does albumin. Called also epidermose..

Serine :: Serine (n.) A white crystalline nitrogenous substance obtained by the action of dilute sulphuric acid on silk gelatin.

Element :: Element (n.) The elements of the alchemists were salt, sulphur, and mercury..

Haematoin :: Haematoin (n.) A substance formed from the hematin of blood, by removal of the iron through the action of concentrated sulphuric acid. Two like bodies, called respectively haematoporphyrin and haematolin, are formed in a similar manner..

Sulphurize :: Sulphuring (n.) Exposure to the fumes of burning sulphur, as in bleaching; the process of bleaching by exposure to the fumes of sulphur..

Catalysis :: Catalysis (n.) A process by which reaction occurs in the presence of certain agents which were formerly believed to exert an influence by mere contact. It is now believed that such reactions are attended with the formation of an intermediate compound or compounds, so that by alternate composition and decomposition the agent is apparenty left unchanged; as, the catalysis of making ether from alcohol by means of sulphuric acid; or catalysis in the action of soluble ferments (as diastase, or ptyali

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.

Mineralizer :: Mineralizer (n.) An element which is combined with a metal, thus forming an ore. Thus, in galena, or lead ore, sulphur is a mineralizer; in hematite, oxygen is a mineralizer..

Sulphamide :: Sulphamic (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..

Oenothionic :: Oenothionic (a.) Pertaining to an acid now called sulphovinic, / ethyl sulphuric, acid..
