| Hazard Information | Back Directory | [General Description]
White odorless crystals or granules that become yellow upon exposure to air. Sinks and mixes in water. | [Reactivity Profile]
Bromine trifluoride reacts explosively with the following AMMONIUM BROMIDE(12124-97-9), ammonium chloride, ammonium iodide [Mellor 2 Supp. 1:165 1956]. | [Air & Water Reactions]
Water soluble | [Health Hazard]
INHALATION: Dust irritating-disturbed behavior, sedation. EYES: Slight irritation. SKIN: Slight irritation only with repeated or prolonged contact. INGESTION: Weakness, nervousness, anorexia, confusion, hallucinations, drowsiness, irritability, ataxia, vertigo, skin rash. | [Fire Hazard]
Special Hazards of Combustion Products: Material decomposes into N 2 and HBr or Br 2 under extreme temperatures. | [Description]
Ammonium bromide is soluble in water and alcohol and is not particularly hazardous under normal conditions. | [Chemical Properties]
white crystals | [Physical properties]
Colorless rhombic crystal; odor of ammonia; sublimes at 60°C; very soluble in cold water; decomposes in hot water; slightly soluble in alcohol; insoluble in acetone. | [Definition]
ChEBI: An ammonium salt composed of ammonium and bromide ions in a 1:1 ratio. | [Preparation]
Ammonium bromide can be prepared by the direct action of hydrogen bromide on ammonia.
NH3 + HBr → NH4Br
| [Flammability and Explosibility]
Nonflammable | [Purification Methods]
It crystallises from 95% EtOH and is slightly hygroscopic. |
