dc.description.abstract The extent of ionic association of (hcpt)4NCl, (hept)4NBr, (hept)4NI, (hcpt)4NNO3 and (oct)4PNO3 in ethanol at 40 C has been measured by vapour pressure osmometry with matched thermistors. The osmotic coefficients, activity coefficients and association constants have been calculated. Ionic association increases with the increasing size of the anion, contrary to the prediction of electrostatic theory of ion pair formation, but in qualitative agreement with the effect of ionic polarizability based on an approximate hard sphere “ dielectric bubble ” model. The association constants are considerably higher than those predicted by the Denison-Ramsay-Fuoss model of contact ion pairs. en_US
