Sulfide

Sulfide

Sulfide (British English sulphide) 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 chemical compounds large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.

The Determination of Sulfate and Sulfide Sulfur in Rocks

The Determination of Sulfate and Sulfide Sulfur in Rocks

A method for the determination of sulfate and sulfide sulfur that occur together in rocks or minerals is presented. All the sulfate sulfur is converted to barium sulfate in an inert atmosphere to prevent oxidation of any sulfide sulfur. Cadmium chloride is added to precipitate any sulfide ion that may be liberated.
