Abstract

The data about cobalt(II) - chloride complexes in acetone solution have been completed by recent spectrophotometric methods (K3=4.5 107; K4=6.1 102). Furthermore, the influence of water addition on the system has been pointed out by considering the dielectric and donor properties of the solvent mixture. The results show a linear correlation of the complex species distribution with the reciprocal dielectric constant of the simple binary system, so that a possible explanation of the present data and of those of some oher authors has been discussed in terms of DEC influence on dissociation reactions. Donor number equality for water and acetone has made it possible to minimize the solvent influence on the ionization processes when varying water-acetone ratio.
