Product Details
Sodium bromide (sodium bromide), is an inorganic compound, chemical formula NaBr, is a colorless cubic crystal or white granular powder, odorless, taste salty and slightly bitter.
Sodium bromide is easy to absorb water in the air and agglomerate, but not deliquescence. Sodium bromide is soluble in water, and the aqueous solution is neutral. Sodium bromide is slightly soluble in alcohol and can react with dilute sulfuric acid to form hydrogen bromide. Under acidic conditions, sodium bromide can be oxidized to free bromine.
Sodium bromide can be used in photosensitive industry, perfume industry, printing and dyeing industry and other industries, can also be used for trace determination of cadmium, manufacturing bromide, inorganic and organic synthesis, photographic paper and so on.
Use:
Used in petroleum, medicine, pesticide, water treatment, dyes, spices, photosensitive film and other industries.
