Initial concentrations of TmCl3 in solvents did not exceed 5.0 mol%. Apparent standard redox potentials of the couples were determined in different solvents. Basic thermodynamic properties of the reaction were calculated. The dependence between the apparent standard redox potentials of the couples and the ionic potential of the solvents was established. |
