Chinese name : 溴化银
English name : Silver bromide
Chemical formula : AgBr
Molecular weight : 187.77
CAS : 7785-23-1
Description : Light yellow powder, hardly soluble in water and ammonia. See light to break out metallic silver. AgBr is photosensitive, and is often used in photographic photographic film. The printing paper is coated with a thin layer of gelatin containing fine silver bromide. When the different light rays are shot on the film, the decomposition of the AgBr on the film is caused to different extent. , bromine and gelatin silver become a very fine silver core nucleation film, which part of the strong AgBr decomposition is more black, and silver bromide is similar to silver iodide, can also be used for artificial precipitation of colloidal materials.
