They are highly flammable and the ammonium sulfide molecular formula is represented as follows (NH4) 2 S. Form Supplied in: the solution in water (20 wt %) is called ‘ammonium sulfide solution – red’ and contains about 30% (NH 4) 2 S, whereas ammonium sulfide – yellow contains 16–20% (NH 4) 2 S. Ammoniumsulfid, zusammen mit Ammoniak, wird häufig in der anorganischen Chemie für eine Qualitative Analyse verwendet, um im Kationentrennungsgang in der Ammoniumsulfidgruppe aus einer unbekannten Probe die Schwermetallkationen der Elemente Nickel, Cobalt, Eisen, Mangan, Chrom, Aluminium und Zink als eine Gruppe auszufällen, aufzutrennen und mithilfe von Nachweisreaktionen zu identifizieren. Ammonium sulfite is a colorless crystalline solid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment.

The employment of ammonium sulfide for a convenient cyclization of α-cyano-α-(dichloromethyleneimino)alkanoic acids, available from the corresponding isocyanides and chlorine, into 5,5-disubstituted 2,4-dithiohydantoins has been described a few years ago (Scheme 39) <1998S1437>. The reaction is proposed to occur by addition of sulfide and cyclization to a thiazole ring followed by ring opening and new closure.

Other articles where Ammonium hydrosulfide is discussed: Jupiter: Cloud composition: …they probably consist of condensed ammonium hydrosulfide and that their colour may be caused by other ammonia-sulfur compounds such as ammonium polysulfides. Sulfur compounds are invoked as the likely colouring agents because sulfur is relatively abundant in the cosmos and hydrogen sulfide is notably absent Substance identity Substance identity. The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases.

At any sulfide loading rates, the consumption efficiencies of sulfide, acetate and ammonium were above 95%, while nitrate consumption efficiencies were around 62-72%. At the highest sulfide loading rate the ammonium was used as electron donor for N(2) production.
