The number of atoms of the element per 1 million atoms of the Earth’s crust. For example, pyrite, which is also called fool’s gold owing to its brassy yellow colour, is a sulfide of iron with the formula FeS2. Sulfides also play a key role during magmatic crystallization in concentrating metals that subsequently may (or may not) be supplied to … 12020-65-4. Summary: The protein encoded by this gene may function in mitochondria to catalyze the conversion of sulfide to persulfides, thereby decreasing toxic concencrations of sulfide. Iron disulfide (pyrite, FeS2) on the other hand consists of S2−2, or −S–S− dianion, in association with divalent iron in the formal +2 oxidation state (ferrous ion: Fe2+). Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S or a compound containing one or more S ions. It contributes no color to sulfide salts. The Pacific Ring of Fire is especially known for its abundance in sulfur reserves. Updates? This is a poisonous gas smelling like rotten eggs; the odour is used in stink bombs, all of which emit a small amount of hydrogen sulfide. The alkali metals and alkaline-earth metals are the only sulfides that have any appreciable water solubility and that appear to be primarily ionic. Sulfide compounds can be prepared in several different ways:[7]. Sulfur is multivalent and combines almost all other elements, with valence 2, 4, or 6. Such species are sometimes referred to as salts. One famous example is the bright yellow species CdS or "cadmium yellow". A further equivalent of metal hydroxide added will yield the metal sulfide. Sulfide and sulfite are two ions formed from sulfur. In the Bible it is called brimstone. It occurs chiefly as the gray sulfide mineral stibnite.

Several have practical applications as pigments, in solar cells, and as catalysts. Sulfide ion has an oxidation number of -2. (Each SiS4 tetrahedron consists of a central silicon atom surrounded by and bonded to four sulfur atoms.) In the Earth’s crust, sulfur is the 5thmost abundant element by mass. Depending on the conditions, the oxidation can produce elemental sulfur, polysulfides, polythionates, sulfite, or sulfate. Another method, particularly suitable for water-soluble sulfides, involves bubbling H2S into a basic solution of the metal to give the metal hydrogen sulfide, MHS. Dissolved free sulfides (H2S, HS− and S2−) are very aggressive species for the corrosion of many metals such as steel, stainless steel, and copper. Hydrogen sulfide (H 2 S) is a gas that smells like rotten eggs. A flame is produced by reaction of the phosphorus sulfide with active chemicals in the match head. A more stable sulfide-type phosphor was produced in 1866 by heating zinc oxide in a stream of hydrogen sulfide.
