Silver bromide is a pale yellow, crystalline substance with silver and bromide ions in a crystal lattice. It breaks down when exposed to light, turning into a pale greyish purple substance, while bromine is formed. It is weakly soluble in water, and can easily be reduced.
Occurrence and production
It precipitates in a reaction of silver nitrate and potassium bromide. It can be found naturally as the mineral bromargyrite, mainly in Mexico.
Silver bromide is used in manufacturing the light-sensitive layers of photographic plates, films and papers and in creating optical windows.
