Sulfide is also a slightly archaic term for thioethers, a common type of organosulfur compound that are well known for their bad odors.The dianion S2? exists only in strongly alkaline aqueous solutions. Such solutions can form by dissolution of H2S or alkali metal salts such as Li2S, Na2S, and K2S in the presence of extra hydroxide. The ion S2? is exceptionally basic with a pKa 14. It does not exist in appreciable concentrations even in highly alkaline water, being undetectable at pH…mehr
