Sulfide (also sulphide in British English) [2] is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.
In organic chemistry, a sulfide (British English sulphide) or thioether is an organosulfur functional group with the connectivity R−S−R' as shown on right. Like many other sulfur-containing compounds, volatile sulfides have foul odors. [1] A sulfide is similar to an ether except that it contains
The sulphide minerals are a class of minerals containing sulphide (S 2−) or disulphide (S 2− 2) as the major anion. Some sulfide minerals are economically important as metal ores. The sulphide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulpharsenides and the sulphosalts.
Hydrogen sulfide is a central participant in the sulfur cycle, the biogeochemical cycle of sulfur on Earth. [112] In the absence of oxygen, sulfur-reducing and sulfate-reducing bacteria derive energy from oxidizing hydrogen or organic molecules by reducing elemental
The energy released in the reaction of sodium and elemental sulfur is the basis of battery technology. The sodium–sulfur battery and the lithium–sulfur battery require high temperatures to maintain liquid polysulfide and Na +-conductive membranes that are unreactive toward sodium, sulfur, and sodium sulfide.
Lead(II) sulfide (also spelled sulphide) is an inorganic compound with the formula Pb S. Galena is the principal ore and the most important compound of lead . It is a semiconducting material with niche uses.
Sulphide (the British English spelling of "sulfide") is a chemical term associated with the following chemical classes: Sulfide; Bisulfide; Disulfide; Thioether; It can also be associated with the name of a geographic location:
Disulfide is also used to refer to compounds that contain two sulfide (S 2−) centers. The compound carbon disulfide , CS 2 is described with the structural formula i.e. S=C=S. This molecule is not a disulfide in the sense that it lacks a S-S bond.
