Étude, Par Spectrométrie Raman, De La Complexation Du ZnCl2 En Solution Aqueuse

We have examined by Raman spectroscopy the autocomplexation of ZnCl2 solutions. Our experiments are in good agreement with previous results. A detailed investigation of the intensity of the band located at about 284 cm−1 has allowed us to confirm the presence of the species ZnCl4− and ZnCl2 at concentrations respectively above 1 M and 4 M. The dissociation constants of the following reactions have been determined: magnified image
