Conductometric Study of Ammonium Bromide in 2-Butanol + Water Mixtures

Molar conductivities of dilute solutions of ammonium bromide in binary mixtures of 2-butanol and water were measured in the temperature range from 288.15 to 308.15 K at 5 K intervals. The limiting molar conductivity (lambda_o) 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 activation energy of the ionic movement (deltaH‡ ) was derived from the temperature dependence of lambda_o. The obtained thermodynamic quantities, together with Walden product, were compared to those for alkali metal bromides and interpreted in terms of the ionic size, as well as solvent basicity, structure and permittivity.
