Overview

Ammonium bromide, NH4Br, is a substance used in manufacturing photographic chemicals and emulsion. It is also used as a flame retardant.

Ammonium bromide can be prepared by the direct action of hydrogen bromide on ammonia. The chemical crystallizes in colourless prisms, possessing a saline taste; it sublimes on heating and is easily soluble in water. On exposure to air it gradually assumes a yellow colour and becomes acid in its reaction.
