Ammonium Sulfide Formula, Preparation Method, Chemical Properties

Ammonium Sulfide Formula

Ammonium sulfide is a solution that is used for to store the liquid securely in a small bottle like container which is sealed in a class called ampoule. It is an inorganic compound in nature. It is more corrosive and hazardous to the environment. The other names that has been referred as rarely called diammonium sulfide. The systematic IUPAC name is known as ammonium sulfide. The chemical or molecular formula of ammonium sulfide is (NH4)2S. this is also known as the ‘stink bomb’.

Structural Formula

This is the structural formula of the ammonium sulfide:

Ammonium Sulfide Formula

Chemical Formula

The chemical formula of the ammonium sulfide is (NH4)2S.


It is the formation of with the help of 1 centered sulfur atom that contains around ammonium cations NH4+ attached to the sulfur.

Preparation Method

When the ammonium sulfide is reacted of ammonium hydroxide with the excess of hydrogen sulfide that can be formed the ammonium hydrosulfide. This is called as an intermediate product. Then further it can be treated with the same quantity of ammonia with the hydrosulfide that gives the ammonium sulfide.
