Metal Derivatives of Sulphide
Metal sulphide derivatives create solid precipitates when sulphide sources such as NaHS, Na2S, and H2S react with transition metal cations in water. Inorganic sulphides are often poorly soluble in water. Cadmium yellow (CdS) is a well-known example, whereas silver sulphide (Ag2S) appears as a black stain on sterling silver, which is commonly referred to as salts.
Transition metal sulphides have extremely covalent bonds, giving them semiconductor characteristics and a wide range of colours. They can be used as pigments, solar cells, and catalysts in a variety of chemical processes.
Sulphides include pyrite (iron disulphide), galena (lead sulphide), argentite (silver sulphide), cinnabar (mercury sulphide), realgar (arsenic sulphide), pentlandite (nickel sulphide), sphalerite (zinc sulphide), and chalcopyrite (iron-copper sulphide).
Sulphide
Sulphide is a chemical product generated when sulphur reacts with another element, usually a metal. It is frequently found in minerals such as pyrite (fool’s gold) and galena. Sulphides frequently emit unique odours (such as rotten eggs), and some are hazardous. They have a variety of purposes in industry, including mining for metals such as copper and lead. Sulphides also have a role in natural processes such as volcanic gas production and some biological activities.
This article deals with sulphides, their basic properties, formula, structure, reactions and commonly used sulphide compounds.
