Abstract

The molar conductivity of the solutions of HBr in 70, 80, 90, and 95 mass per cent tert-butanol was measured in the temperature range from 288.15 to 308.15 K at 5 K intervals. The measured values were processed by the conductance equations after Fuoss-Hsia and Lee-Wheaton using different calculating methods. The obtained values for limiting molar conductivity (yl0), distance parameter (R) and association constant (KA) were compared and discussed. The association constants obtained at different temperatures under the condition R = q (q is Bjerrum critical distance) were used to calculate the standard thermodynamic quantities for the association reaction of H+ and Br- ions. The obtained values for KA were also compared with the theoretically predicted values.
