Most often in sulfur chemistry and in biochemistry, the disulfide term is commonly ascribed to the sulfur analogue of the peroxide –O–O– bond. The tips of strike-anywhere matches contain P4S3, which ignites in air as a result of the friction produced when the match is rubbed against a rough surface. Professor and Associate Head, Department of Chemistry, University of Illinois at Urbana-Champaign. The preferred descriptor for such SH-containing compounds is thiol or mercaptan, i.e. Formation, basic properties, related materials. 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. sulfanylideneeuropium. Sulfide also refers to chemical compounds large families of inorganic and organic compounds, e.g. Biogenic sulfuric acid reacts with sewerage materials and most generally causes mass loss, cracking of the sewer pipes and ultimately, structural collapse. Author of. Hydrogen sulfide quickly deadens the sense of smell. Its ranked 10th in order of abundance among all elements in the universe. Sulfur dioxide (SO 2), formed by burning sulfur in air, is used as a bleaching agent, solvent, disinfectant and as a refrigerant. Sulfites or sulphites are compounds that contain the sulfite ion (or the sulfate(IV) ion, from its correct systematic name), SO 3.

One famous example is the bright yellow species CdS or "cadmium yellow". Zinc, cadmium, mercury, copper, silver, and many other elements occur in nature as sulfides. Sulfide ion has an oxidation number of -2. The name may have been derived from the Arabic ‘sufra’ meaning yellow, or the Sanskrit ‘shulbari’ meaning enemy (ari) of copper (shulba). Sulfide is a related term of sulfur. ... Hell that smells like hydrogen sulfide or any number of organic-sulfur compound will not be a nice place at all. Several have practical applications as pigments, in solar cells, and as catalysts. An efficient flotation process was developed to selectively recover elemental sulfur from a high-sulfur pressure acid leaching residue of zinc sulfide concentrate. Occasionally, the term sulfide refers to molecules containing the –SH functional group. 07:52 The most important nickel mineral is pentlandite, (Ni, Fe). Oxidation of sulfide can also form thiosulfate (S2O2−3) an intermediate species responsible for severe problems of pitting corrosion of steel and stainless steel while the medium is also acidified by the production of sulfuric acid when oxidation is more advanced.
