Standard Gibbs energies of transfer of halogenate and pseudohalogenate ions, halogen substituted acetates, and cycloalkyl carboxylate anions at the water backslash nitrobenzene interface

摘要

The previously introduced three-phase electrode technique was used to determine the Gibbs energies of transfer of ClO3-, BrO3-, IO3-, IO4-, OCN-, SeCN-, CN-, N-3(-), halogen substituted acetate anions Z(3-n)CH(n)COO(-) (Z = F,Cl,Br,I), and cycloalkyl carboxylate anions ((CH2)(n)COO-, n = 3,...,7) at the wateritrobenzene 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.
