Abstract

The previously introduced three-phase electrode technique was used to determine the Gibbs energies of transfer of ClO3 �, BrO3 �, IO3 �, IO4 �, OCN�, SeCN�, CN�, N3 �, halogen substituted acetate anions Z3�nCHnCOO� (Z ¼ F,Cl,Br,I), and cycloalkyl carboxylate anions ((CH2)nCOO�, n ¼ 3,. . .,7) at the water|nitrobenzene interface. Whereas the data for the small inorganic ions can easily be understood in terms of ion-dipole interactions, the data of the organic ions need consideration of charge delocalisation and its effect on the enthalpy and entropy of solvation.
