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.
Lime sulfur reacts with strong acids (including stomach acid) to produce highly toxic hydrogen sulfide (rotten egg gas) and indeed usually has a distinct "rotten egg" odor to it. Lime sulfur is not flammable but can release highly irritating sulfur dioxide gas when in a fire. Safety goggles and impervious gloves must be worn while handling lime ...
Phosphorus sulfides comprise a family of inorganic compounds containing only phosphorus and sulfur.These compounds have the formula P 4 S n with n ≤ 10. Two are of commercial significance, phosphorus pentasulfide (P 4 S 10), which is made on a kiloton scale for the production of other organosulfur compounds, and phosphorus sesquisulfide (P 4 S 3), used in the production of "strike anywhere ...
The nonbonding electrons on sulfur are delocalized into the π-system. As a consequence, thiophene exhibits few properties expected for a sulfide – thiophene is non-nucleophilic at sulfur and, in fact, is sweet-smelling. Upon hydrogenation, thiophene gives tetrahydrothiophene, C 4 H 8 S, which indeed does behave as a typical sulfide.
Bis(2-chloroethyl)sulfide is the organosulfur compound with the formula (ClCH 2 CH 2) 2 S. It is a prominent member of a family of cytotoxic and blister agents known as mustard agents. Sometimes referred to as mustard gas , the term is technically incorrect: bis(2-chloroethyl)sulfide is a liquid at room temperature.
Sodium polysulfide can be produced by dissolving sulfur in a solution of sodium sulfide. [4] Alternatively they are produced by the redox reaction of aqueous sodium hydroxide with sulfur at elevated temperatures. [5] Finally they arise by the reduction of elemental sulfur with sodium, a reaction often conducted in anhydrous ammonia.
Silver sulfide is an inorganic compound with the formula Ag 2 S. A dense black solid, it is the only sulfide of silver. It is useful as a photosensitizer in photography. It constitutes the tarnish that forms over time on silverware and other silver objects. Silver sulfide is insoluble in most solvents, but is degraded by strong acids. Silver ...
[1] [2] Anaerobic sulfur oxidizers include photolithoautotrophs that obtain their energy from sunlight, hydrogen from sulfide, and carbon from carbon dioxide (CO 2). [3] Most of the sulfur oxidizers are autotrophs that can use reduced sulfur species as electron donors for CO 2 fixation.
