Using this approach, bisulfide has been detected in the ocean and in sewage. The absorption of bisulfide is observed around 230 nm in each case.Īqueous bisulfide absorbs light at around 230 nm in the UV–visible spectrum. The UV–visible spectrum of septic sewage from three different sites. For example, the hydrated form of sodium sulfide, nominally with the formula Na 2S Some compounds described as salts of the sulfide dianion contain primarily hydrosulfide. Ammonium hydrosulfide, a component of 'stink bombs' has not been isolated as a pure solid. It is an important chemical reagent and an industrial chemical, mainly used in paper pulp industry ( Kraft process), textiles, synthetic flavors, coloring brasses, and iron control.Ī variety of salts are known, including sodium hydrosulfide and potassium hydrosulfide. Bisulfide solutions are corrosive and attack the skin. It contributes no color to bisulfide salts, and its salts may have a distinctive putrid smell. Bisulfide (or bisulphide in British English) is an inorganic anion with the chemical formula HS − (also written as SH −).
