Sulphur

Sul´phur
n.1.(Chem.) A nonmetallic element occurring naturally in large quantities, either combined as in the sulphides (as pyrites) and sulphates (as gypsum), or native in volcanic regions, in vast beds mixed with gypsum and various earthy materials, from which it is melted out. Symbol S. Atomic weight 32. The specific gravity of ordinary octohedral sulphur is 2.05; of prismatic sulphur, 1.96.
2.(Zool.) Any one of numerous species of yellow or orange butterflies of the subfamily Pierinæ; as, the clouded sulphur (Eurymus philodice syn. Colias philodice), which is the common yellow butterfly of the Eastern United States.
Amorphous sulphur
(Chem.) an elastic variety of sulphur of a resinous appearance, obtained by pouring melted sulphur into water. On standing, it passes back into a brittle crystalline modification.
Liver of sulphur
(Old Chem.) See Hepar.
Sulphur acid
(Chem.) See Sulphacid.
Sulphur alcohol
(Chem.) See Mercaptan.
Sulphur auratum
(Old Chem.) a golden yellow powder, consisting of antimonic sulphide, Sb2S5, - formerly a famous nostrum.
Sulphur base
(Chem.) an alkaline sulphide capable of acting as a base in the formation of sulphur salts according to the old dual theory of salts.
Sulphur dioxide
(Chem.) a colorless gas, SO2, of a pungent, suffocating odor, produced by the burning of sulphur. It is employed chiefly in the production of sulphuric acid, and as a reagent in bleaching; - called also sulphurous anhydride, and formerly sulphurous acid.
Sulphur ether
(Chem.) a sulphide of hydrocarbon radicals, formed like the ordinary ethers, which are oxides, but with sulphur in the place of oxygen.
Sulphur salt
(Chem.) a salt of a sulphacid; a sulphosalt.
Sulphur showers
showers of yellow pollen, resembling sulphur in appearance, often carried from pine forests by the wind to a great distance.
Sulphur trioxide
(Chem.) a white crystalline solid, SO3, obtained by oxidation of sulphur dioxide. It dissolves in water with a hissing noise and the production of heat, forming sulphuric acid, and is employed as a dehydrating agent. Called also sulphuric anhydride, and formerly sulphuric acid.
Sulphur whale
(Zool.) See Sulphur-bottom.
Vegetable sulphur
(Bot.) lycopodium powder. See under Lycopodium.
Noun1.sulphur - an abundant tasteless odorless multivalent nonmetallic element; best known in yellow crystals; occurs in many sulphide and sulphate minerals and even in native form (especially in volcanic regions)
Verb1.sulphur - treat with sulphur in order to preserve; "These dried fruits are sulphured"
