摘要
Gibbs energies, entropies (given as T Delta(1)S degrees values), and enthalpies of transfer of cations from water into nonaqueous solvents are derived from electrochemical measurements. The Gibbs energies of transfer for the cations were based on the bis(biphenyl)chromium assumption. Values of T Delta(1)S degrees were derived from the assumption of a negligible thermal diffusion potential. Enthalpies of transfer were calculated from the Gibbs energies and T Delta(1)S degrees values. Comparison with data from the tetraphenylarsonium tetraphenylborate assumption is made. The applicability of transfer properties in understanding the physico-chemistry of chemical reactions in solution is suggested.
