The preparation and vapour pressures of the indium(I) halides and the standard molar Gibbs free energy change for formation of InX from In(g) and X2(g), (X = Cl, Br, or I)

The thermodynamics of the vaporization of liquid indium(I) bromide by modified entrainment

“…Experimental Materials Indium(1) bromide, a bright orange crystalline material, was prepared by reaction of high purity samples of indium metal and bromine; it was part of the same batch used in the quasi-static vapour pressure manometry study (2) and its synthesis has been described (2) in detail. Indium analyses by EDTA titration were 58.98 and 58.52 mass% and bromine analysis by potentiometric titration of the hydrolysate using a reversible silver: silver bromide electrode gave 41.0 mass percent (for InBr, In = 58.96%; Br = 41.04%).…”
