Indium tribromide, InBr3






Indium tribromide, InBr3, is prepared by the action of bromine vapour upon heated indium, and may be sublimed in a current of carbon dioxide. It resembles the trichloride in properties. Numerous physical properties of indium tribromide solutions have been measured by Heydweiller. The equivalent conductivities at 18° are as follows: -
