The molar conductivities of HBr in the 90 and 95 mass per cent 2-met- hyl-2-propanol-water and 1-butanol-water mixtures, respectively, were measured in the temperature range from 288.15 to 308. 15 K at 5 K intervals.

By means of the conductance equations after Fuoss-Hsia and Lee-Wheaton the limiting molar conductivity Ao, association constant KA and the radius of the ion pair R were obtained from these data. The data for R differ considerably, so that KA and A0 were also calculated with the same equations under the condition that R = q q is the Bjerrum critical distance. The influence of the dielectric constant on KA and Ao was established and discussed and comparison was made with analogous literature data for 2-butanol-water and tert. butanol-water mixtures. From the data for KA at different temperatures under the conditionR = q the standard thermodynamic quantities for association reaction of H+ and Br- were determined.
