Abstract: The systems Cu⁺⁺, Cl^- and Br^- in acetone, CuCl₂ in acetone, and CuBr₂ in acetone were studied by a spectrophotometric method. The complex ion CuCl₃Br^-- (I) forms in acetone. I changes with time and the velocity of this change increases with the increase of concn. of free Br^-. The velocity of the reduction of Cu⁺⁺ to Cu⁺ in halogen cupric complexes (II) in acetone decreases in the order CuI₂, CuBr₂, CuCl₂ and is favorably affected by an unequal formation on the inner sphere of II. The results of these detns. favor the hypothesis of the existence of transeffect in II.
