Abstract. The work deals with polyvalent electrolytes conductometric investigation of CuCl2,[Cu(en)2]Cl2, FeCl3 solutions in binary mixed solvent DMSO−CB in a wide range of electrolyteconcentrations (10-6–10-2 mol/dm3). Investigations were carried out at the temperature interval 298,15–323,15 K. Ion association constants (Kai) for given non-symmetrical electrolytes were calculated for twostages of association. Integral thermodynamic characteristics (Gai, Hai, Sai) of stage ion associationprocess were calculated. The comparison of thermodynamic characteristics of equilibrium processes allowsto make a conclusion about relative influence of polar and donor properties of medium on the processes ofstage ion association in polyvalent electrolyte solutions.Keywords: conductometric investigation, ion association constants, polyvalent electrolytes, solutionequilibrium processes, thermodynamic characteristics.References
