Synthesis of ammonium sulfide

Preparation of ammonium sulfide

By treating ammonium hydroxide with an excess of hydrogen sulfide ammonium hydrosulfide (NH4HS) forms, which with further treatment with the same quantity of ammonia yields ammonium sulfide:

Preparation of ammonium sulfide

Preparation of ammonium sulfide

Hydrogen sulfide is passed through 3 parts of concentrated ammonium hydroxide solution until no further absorption takes place. Then 2 parts of concentrated ammonium hydroxide solution is added in order to neutralize NH4HS. The rule, however, is to add only two-thirds of the quantity of solution of ammonium hydroxide, as it is better the preparation should contain a little ammonium hydrosulfide than that free ammonia should be present. Ammonium sulfide should be well protected from air and moisture.
