Ammonium Bromide
Ammonium Bromide
Ammonium Bromide, NH4Br, is the ammonium salt of hydrobromic acid. The chemical crystallizes into colorless prisms, possessing a saline taste. It sublimes on heating and is easily soluble in water. On exposure to air it gradually assumes a yellow color because of the oxidation of traces of bromide (Br–) to bromine (Br2). Ammonium bromide is used for photography in films, plates and papers; in fireproofing of wood; in lithography and process engraving; in corrosion inhibitors; and in pharmaceutical preparations.
Applications
Ammonium Bromide is used for photography in films, plates and papers; in fireproofing of wood; in lithography and process engraving; in corrosion inhibitors; and in pharmaceutical preparations. Ammonium Bromide used in combination with an appropriate oxidizer is an efficient biocide, applied in various industrial water systems and waste water, to control bacteria, fungi and algae.
