Sažetak
Molar conductivities of dilute solutions of ammonium bromide in binary mixtures of butan-2-ol and water were measured in the temperature range from 288.15 to 308.15 K at 5 K intervals. The limiting molar conductivity and the ion-pair formation constant (K A ) were determined by the Lee-Wheaton conductivity equation. Thermodynamic quantities, Gibbs energy (ΔG°), enthalpy (ΔH°) and entropy (ΔS°), for the ion-association reaction were derived from the temperature dependence of KA. The activation enthalpy of the charge transport was derived from the temperature dependence of Λo. The obtained thermodynamic quantities, together with Walden product, were discussed in terms of solvent basicity, structure permittivity and viscosity
