Abstract: The effect was studied of an excess of free chloride and bromide ions on solns. of AlCl₃ and AlBr₃ in acetonitrile. The polarog. study showed no essential changes in the polarog. record when identical halides were added. The addn. of bromide ions to AlCl₃ soln. causes a remarkable positive shift of the half-wave potential of AlCl₃. The addn. of chloride ions to AlBr₃ soln. results in a total elimination of the neg. wave of AlBr₃. These effects are discussed from the point of view of ionization and complex formation equilibria of the investigated systems.
