When the ampoule is broken, ammonia and hydrogen sulfide gases are released from the solution. Ammonium sulfide is a yellowish solid compound at low temperatures, but unstable above -18 °C, with a very strong and highly unpleasant smell of rotten eggs. It is very soluble in water and ammonia , as well as alcohols . Following transfer of Pb-exposed fish to a weak ammonium sulfide solution, Carpenter (1927) noted a black coloration of the mucus film attributed to precipitated Pb sulfide. It was therefore suggested, and later substantiated by Westfall (1945) , that the cause of acute mortality was suffocation due to the inability to clear a Pb-induced coagulation of mucus at the gill. AMMONIUM SULFIDE SOLUTION is a strongly alkaline aqueous solution. Reacts with acids to generate toxic gaseous hydrogen sulfide.

Ammonium sulfide is a very useful reagent in mineral analysis. Used in continuous culture of saccharomyces cerevisiae, useful in a double staining technique for visualization of astrocytes and microglia from brain sections and astroglial cell cultures. Ammonium sulfide is a food additive permitted for direct addition to food for human consumption, as long as 1) the quantity added to food does not exceed the amount reasonably required to accomplish its intended physical, nutritive, or other technical effect in food, and 2) when intended for use in or on food it is of appropriate food grade and is prepared and handled as a food ingredient. 2008-11-23
