✦ Synopsis

The emfof the cell: Cu/Cu'+, water + organiccu-solvent/water, Cu'+//Cu with sulfolane, dioxan. tetrahydrofuran, acetone and dimethylsulphoxide (DMSO) ss organic w-solvents has been measured for different solvent compositions. To decrease the liquid junction potential the salt bridge filled with the methanolic solution of tetrabutylsmmonium picrate has been applied. The e&data were used to calculate the Gibbs free energy ofcopper(II)cation transfer from water to nonaqueous or mixed solvents. Determined free energies of transfer are negative for DMSO and positive for other organic solvents.
