| | Ammonium bromide Usage And Synthesis |
| 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. | | Uses | A chemical used for its bromide ion | | Uses | manufacture of photographic films, plates, and papers; in process engraving and lithography; fireproofing of wood; in corrosion inhibitors. | | Uses | Colorless crystals made by hydrobromic acid acting upon
ammonium hydroxide followed by crystallization. Soluble in
ether, alcohol, and water, ammonium bromide was used as
a halide in collodion formulas and as a restrainer in alkaline
developers. | | Definition | ChEBI: An ammonium salt composed of ammonium and bromide ions in a 1:1 ratio. | | General Description | White odorless crystals or granules that become yellow upon exposure to air. Sinks and mixes in water. | | Air & Water Reactions | Water soluble | | Reactivity Profile | Bromine trifluoride reacts explosively with the following Ammonium bromide, ammonium chloride, ammonium iodide [Mellor 2 Supp. 1:165 1956]. | | 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. | | Flammability and Explosibility | Nonflammable | | Purification Methods | It crystallises from 95% EtOH and is slightly hygroscopic. |
