Anwendungen & Verwendung
Beschreibung
Ammonium bromide is soluble in water and alcohol and is not particularly hazardous under normal conditions.
Verwenden
Ammonium bromide is a colorless crystals used for its bromide ion, it was also used as a halide in collodion formulas and as a restrainer in alkaline developers.
Herstellung & Synthese
synthetische
Ammonium bromide can be prepared by the direct action of hydrogen bromide on ammonia. NH3 + HBr → NH4Br
