What is Ammonium bromide?

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.

The Uses of Ammonium bromide

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.

The Uses of Ammonium bromide

A chemical used for its bromide ion

The Uses of Ammonium bromide

manufacture of photographic films, plates, and papers; in process engraving and lithography; fireproofing of wood; in corrosion inhibitors.

What are the applications of Application
