Sažetak
Molar conductivity of LiBr solutions in 2-butanol + water mixtures (w2-BuOH = 0.7, 0.8, 0.9, 0.95) was measured at five temperatures in the temperature range from 288.15 to 308.15 K. The limiting molar conductivity (Λ0), association constant (Ka) and association distance (R) were calculated using the Lee-Wheaton equation. Three-parameter adjustment did not produce uniform values of R. Consequently, the treatment was repeated by the two-parameter version of this equation with R fixed at q (q is Bjerrum's critical distance). The Walden product values, as well as the standard thermodynamic quantities for the association reaction at 298.15 K, were derived from the temperature dependent Λ0 and Ka, respectively. All quantities obtained are reported and discussed.
