Calcium bromide is an inorganic salt with the molecular formula CaBr2. It is a colorless oblique needle shaped crystal or crystal block, odorless, with a salty and bitter taste. Relative density 3.353 (25 ℃). Very soluble in water, neutral in aqueous solution, soluble in ethanol, acetone, and acid, slightly soluble in methanol and liquid ammonia, insoluble in ether or chloroform. Can form double salts with alkali metal halides. Has strong hygroscopicity. Used for oil drilling, as well as for manufacturing ammonium bromide, photosensitive paper, fire extinguishing agents, refrigerants, etc.
