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 CuCl42- 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 CuCl42- is relatively stable to oxidation-reduction changes.
