Sažetak
Molar conductivities of HBr in 70, 80, 90 and 95 mass per cent 2-butanol-water mixtures were measured in the temperature range from 288.15 to 308.15 K at 5 K intervals. The experimental values were analyzed by the conductance equations after Fuoss-Hsia and Lee-Wheaton. Values for the limiting molar conductivity (lambda_o), obtained by both equations, agree well, better than the association constant (K_A), while the distance parameters (R) differ considerably. Both equations were used to calculate the association constants at different temperatures under the condition that R=q (q is Bjerrum critical distance). These values were used to obtain standard thermodynamic quantities for the H+ and Br- ion association reaction. The values obtained were compared with the literature data for tert. butanol-water mixtures. The mechanism of H+ ion transfer in the investigated mixtures was also discussed.
