Density, viscosity and electrolytic conductivity of concentrated aqueous solutions of alkaline-earth halides have been evaluated.[1] Application Potassium bromide may be employed in the following studies: - Spectrophotometric determination of aromatic amino compounds.[2] - Preparation of AgBr nanoparticles (NPs).[3] - In combination with cerium(iv) ammonium nitrate (CAN), has been employed for the bromination of alkenes.[4] - As oxidant for the selective monobromination of various deactivated anilines.[5] May be used for removal of peripheral membrane proteins. |
