Thermodynamics of the Association Reaction of RbBr in Binary Mixtures of 2-Butanol and Water from 288.15 to 308.15 K

Molar conductivities of dilute solutions of rubidium 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 (Lamda_o) and association constant (K_A) were determined by treating experimental data with the Lee-Wheaton conductivity equation. Thermodynamic quantities for the ion-association reaction were derived from the temperature dependence of K_A. The obtained results provide information on ion-ion and ion-solvent interactions.
