Potassium bromide Chemical Properties,Usage,Production

Chemical Properties
odourless white or colourless crystalline solid
May be used for removal of peripheral membrane proteins.
General Description
Odorless colorless crystals or white crystalline powder or white granular solid with a pungent bitter saline taste. Aqueous solutions are neutral (pH about 7).
Air & Water Reactions
Water soluble.
Reactivity Profile
Potassium bromide is not in generally strongly reactive. A weak reducing agent, incompatible with oxidizing agents. Also incompatible with salts of mercury and silver. Violent reactions occur with bromine trifluoride. May react with nitrous ether spirit, many alkaloidal salts and starch. May also react with acids . Reacts with concentrated sulfuric acid to generate fumes of hydrogen bromide.
Fire Hazard
Flash point data for Potassium bromide are not available; however, Potassium bromide is probably nonflammable.
