Abstract: cf. C.A. 51, 6418b. The binary system CuCl₂-acetone (I) was studied by the spectrophotometric method. It was detd. from the absorption curves that the light absorption in the visible area of freshly prepd. CuCl₂ soln. in the acetone is due to the presence of CuCl₄^2- ions. The optical properties of I change spontaneously with time and are due to the reduction of CuCl₂ to CuCl. The light absorption of I with a low concn. of CuCl₂ (0.001M), after 80 days is very similar to aq. cupric solns. Cu²⁺ in CuCl₄^2- is relatively stable to oxidation-reduction changes.
