Sažetak
Molar conductivity of the NH4Br solutions in binary mixture of 2-butanol and water with 5 mass % alcohol content was measured at five temperatures in the range from 15 °C to 35 °C. The limiting molar conductivity and the ion-pair formation constant (KA) were determined by the Lee-Wheaton conductivity equation. Thermodynamic quantities, Gibbs energy, enthalpy and entropy for the ion-association reaction were derived from the temperature dependence of KA. The obtained thermodynamic quantities, together with Walden product, were compared with literature data for NH4Br in mixtures with 2-butanol mass fraction (w) 70, 80, 90 and 95 %.
