Determination of the Equilibrium Constants and UV-Absorption Spectra for Cu2+- Cl- Complexes in 1M HClO4

• The complex constants for the Cu(II)-chloride complexes CuCl+ and CuCl2 have been determined spectrophotometrically at 25°C and in 1 M HClO4. The evaluation procedure employed was a regression analysis for the simultaneous determination of complex constants and absorption spectra and yielded K1 = 2.3 ± 0.4 and K2 = 0.72 ± 0.09. There is a strong overlap between the 2 absorption spectra (λmax = 250 nm in both cases, ε1=530, , ε2 = 1620) which made it particularly necessary to arrange the numerical analysis in such a way that the spectral differences were fully exploited.
