Ammonium sulfide ((NH4)2(S2))

Ammonium sulfide, with the chemical formula (NH₄)₂S₂, is an inorganic compound composed of two ammonium ions (NH₄⁺) and one disulfide ion (S₂²⁻). Its molecular weight is 100.21 g/mol. Ammonium disulfide is oxidized to form ammonium sulfate ((NH₄)₂SO₄) and elemental sulfur.

Ammonium sulfide can be produced by the reaction of ammonium sulfide ((NH₄)₂S) with elemental sulfur (S). In industry, ammonium sulfide is produced by passing hydrogen sulfide (H₂S) gas through concentrated ammonia (NH₃) solution. Ammonium sulfide is used as a reagent for the synthesis of sulfur-containing compounds and as a source of disulfide ions in various chemical reactions. In addition, it can be used to study the formation of disulfide bonds in proteins and peptides, which is crucial for understanding protein folding and stability.
