Phycial Properties :  Sodium Bromide is a toxic , white , crystalline sodium compound , free from extraneous impurities . It is thoroughly  soluble in water and partially  soluble in alchohol .It is  thermally stable . It absorbs moisture from its surroundings  and has a saline and a bitter taste. Its molecular weight is 102.9 and  melts at 758 degree C .It resembles a lot to sodium chloride .

Chemicals Properties : One way to make sodium bromide is to react  hydroxide with hydrobromic acid. It is then purified by the method of recrystallization. 

 Uses  : Sodium Bromide is  employed in the preparation of photographic emulsions  and further in its processing ..It act as a chemical intermediate for the manufacture of various chemicals, and bromides. To obtain HBr , NaBr is treated with a strong , non-volatile acid .  It is used for water clarification and  thus involves itself in pool treatment product .It is also used as a wood preservative and a flame retardant . Sodium bromide absorbs moisture when exposed to the atmosphere therefore it should be stored in an air tight container in a dry place .
