Okan, D. Champeney] The electrical conductivities of aqueous solutions of NaCF3SO3, KCF3SO3, and Ni(CF3SO3)2 have been measured at 25‡C in the concentration range 1 to 25X 10-3 mol-dm-3 The data approach the Onsager limiting law at low concentrations, leading to a limiting molar ion conductivity for the CF3SO 3 − ion of 44.5±0.2 S-cm2-mol-1, based on standard values for the cations. Using a simple size parameter for unsymmetrical polyatomic ions, based on the ion geometry, it is shown that the well known empirical relation between the molar conductivities of symmetrical ions and their radii can be extended to include certain polyatomic anions including CF3SO 3 − . The results suggest that the CF3SO 3 − ion is either a weak structure breaker in aqueous solution or neutral in this respect.
