The stoichiometric equilibrium constants, K 3 *, for the formation of CuX 3 2- from CuX 2 - +X- where X=Cl and Br, have been determined from spectral measurements. The measurements were made in NaCl and NaBr solutions from I=0.5 to 6.0m at 5, 25 and 45°C. The measured constants were extrapolated to infinite dilution using the Pitzer equations. The Pitzer parameters, β0, β1 and Cφ, for the interaction of Na+ with CuX 2 - and CuX 3 2- are briefly discussed.
