Ammonium bromide Definition
An ammonium salt composed of ammonium and bromide ions in a 1:1 ratio.
Ammonium bromide Uses
1. A chemical used for its bromide ion
2. manufacture of photographic films, plates, and papers; in process engraving and lithography; fireproofing of wood; in corrosion inhibitors.
3. 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.
