Conductivity study of NaI solutions in n-propanol–n-butanol mixtures at 298.15 K

Abstract

The electrical conductivity of NaI solutions in binary n-propanol–n-butanol mixtures within the whole composition range has been measured and analysed using the Fuoss–Justice equation. With increasing n-butanol content the limiting molar conductance decreased and the equilibrium constant of ion-pair formation increased. The standard dissolution enthalpies of NaI in the same binary mixtures (published earlier) have been recalculated taking into account the ion-association process.
