Determination of trace cadmium for analytical chemistry, photographic plate, pharmaceuticals. Physical and chemical properties of colorless cubic crystal or white granular powder. Odorless, slightly bitter taste and a base. The relative density of 3.203 (25 ). Melting point 747 . There are hygroscopic in the air. Soluble in water (100 when the solubility of 121g / 100ml water), aqueous solution is neutral. Slightly soluble in alcohol. 51 in the solution of anhydrous sodium bromide precipitated crystals were lower than 51 is generated dihydrate. Bromide ion which may be substituted by chlorine.

 

Under acidic conditions, it can be oxidized by oxygen, free bromine. Capable of reacting with silver ions generated as a pale yellow solid silver bromide can be reacted with sulfuric acid to generate hydrogen bromide, concentrated sulfuric acid reacts with bromine. Chlorine gas can also be replaced with elemental bromine, bromine water is one of process.
