Sodium bromide (Sodium bromide), is an inorganic compound with the formula NaBr, is a colorless cubic crystal or white granular powder, odorless, salty and slightly bitter. Sodium bromide easily absorbs moisture in the air and agglomerates, but does not deliquescence.

Sodium bromide is easily soluble in water, and the aqueous solution is neutral. Sodium bromide is slightly soluble in alcohol and can react with dilute sulfuric acid to generate hydrogen bromide. Under acidic conditions, sodium bromide can be oxidized to free bromine.

Sodium bromide can be used in photosensitive industry, fragrance industry, printing and dyeing industry and other industries, but also for trace determination of cadmium, manufacture of bromide, inorganic and organic synthesis, photographic paper plates and other aspects.
