Transfer gibbs energies for ClO –3, BrO –3, IO –3, ClO –4 and IO –4 anions for water–acetonitrile and water–tert-butyl alcohol mixtures

Abstract

The transfer Gibbs energies, Δ_trsG, of KClO₃, KBrO₃, KlO₃, KClO₄, KlO₄ and the corresponding caesium salts have been obtained through the gravimetric measurement of solubility in aqueous mixtures with acetonitrile (AN) and tert-butyl alcohol (Bu ^tOH). Single-ion values of Δ_trsG have been calculated using the TATB assumption. The trends observed for Δ_trsG are discussed in terms of specific ion–solvent interactions and the structural effect of the solvent mixtures.
