Sodium bromide readily absorbs moisture in the air and agglomerates, but does not deliquesce. Sodium bromide is readily 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 the photographic industry, perfume industry, printing and dyeing industry, etc. It can also be used for micro-determination of cadmium, manufacture of bromide, inorganic and organic synthesis, photographic paper and so on.
