Ammonium sulfide, also known as diammonium sulfide, is an unstable salt with the formula (NH4)2S. Aqueous solutions purporting to contain this salt are commercially available. With a p''K''a exceeding 15,〔Meyer B, Ward K, Koshlap K, Peter L "Second dissociation constant of hydrogen sulfide" ''Inorganic Chemistry', (1983). volume 22, pp. 2345.〕 the hydrosulfide ion cannot be deprotonated to an appreciable amount by ammonia. Thus, such solutions mainly consist of a mixture of ammonia and (NH4)SH. Ammonium sulfide solutions are used occasionally in photographic developing, to apply patina to bronze, and in textile manufacturing. Also, due to its offensive smell, it is the active ingredient in a variety of foul pranks including the common stink bomb.
It can be used as a selective reducing agent (cf Clonitazene), where there are 2 nitro groups only one of them is selectively reduced.
==Safety==
Solutions of "ammonium sulfide" are hazardous as labile sources of toxic hydrogen sulfide.〔(J. T. Baker: MSDS for Ammonium Sulfide )〕
