Usage

Description

Ammonium bromide is an ammonium salt composed of ammonium and bromide ions in a 1:1 ratio, forming colorless rhombic crystals with an odor of ammonia. It is soluble in water, ether, and alcohol, and decomposes in hot water. It is used in various applications due to its chemical properties.

Uses

Used in Chemical Applications:
Ammonium bromide is used as a source of bromide ions for various chemical reactions and processes.
Used in Photography Industry:
Ammonium bromide is used as a halide in collodion formulas and as a restrainer in alkaline developers for the manufacture of photographic films, plates, and papers.
Used in Engraving and Lithography:
Ammonium bromide is utilized in the process engraving and lithography due to its properties as a halide.
Used in Fireproofing Industry:
Ammonium bromide is employed for fireproofing wood, providing an additional layer of protection against fire damage.
Used in Corrosion Inhibition:
Ammonium bromide is used as a corrosion inhibitor, helping to prevent the degradation of materials in various industrial applications.
Physical properties:
Ammonium bromide is a white, odorless crystalline substance that becomes yellow upon exposure to air. It sinks and mixes in water and sublimes at 60°C. It is slightly soluble in alcohol and insoluble in acetone.
