Abstract

The stoichiometric equilibrium constants, K₃^*, for the formation of CuX₃^2- from CuX₂^- +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 C^φ, for the interaction of Na⁺ with CuX₂^- and CuX₃^2- are briefly discussed.
