Summary

Conductances of PhCO2Ag in 0, 10, 20, 40 and 60% (w/w) MeOH−H2O mixtures were measured at 35° C and analysed using the Fuoss-Hsia equation for thermodynamic association constants (KA) and molar conductances at infinite dilution (Λ0). The modified Denison-Ramsey (MDR) equation KA=3.025 exp (155.96/D) described best the log KA: 1/D data for the ion pair equilibria. In view of the observed association constants and the value of the parameter ‘a’ (3.48 Å), a dynamic equilibrium between solvent separated and contact ionpairs was proposed and equilibrium constants for the interconversions of those forms were calculated.
