Description

Yellow crystals that are unstable at room temperature or in the presence of moisture. Ammonium sulfide is sold commercially as a liquid that is primarily composed of ammonium bisulfide, NH4HS. Ammonium sulfide is used in photographic developers, in the manufacture of textiles, and to produce a dark patina on brasses and bronzes.

Synonyms and Related Terms

diammonium sulfide; aqueous ammonium sulfide

  • Evolves hydrogen sulfide on contact with acids.
  • Strongly irritating to skin and membranes.
  • Flammable. Flash point = 22 C
  • Fisher Scientific: SDS
