Ammoniumsulfide is een instabiel zout met de formule (NH 4) 2 S. Veel chemicaliënleveranciers bieden waterige oplossingen van dit zout aan. Omdat de p Ka van het waterstofsulfideion boven de 15 ligt, kan dit ion door ammoniak zeker niet volledig gedeprotoneerd worden.

Ammonium sulfide, also known as the " stink bomb " is made up of a solution of ammonium sulfide in water, sealed inside a glass ampoule (a small bottle-like container used to store a liquid securely). When the ampoule is broken, ammonia and hydrogen sulfide gases are released from the solution. These chemicals have a very strong and unpleasant
