Sažetak

Molar conductivities of electrolyte NaBr in tert-butanol-water mixtures (“VBuOH = 0-7, 0.8, 0.9, 0.95) were measured in a temperature range from 288.15 to 308.15 K at 5 K intervals. These data were processed by means of conductivity equations after Fuoss-Hsia and Lee-Wheaton. The obtained values for limiting molar conductivity (A0), association constant (JfA) and distance parameter (R) were compared and discussed. The calculation was repeated for a two-parameter version of these equations with R = <7Bjerrum- The obtained association constants at different temperatures were used in determining the standard thermodynamic quantities of the association reaction of Na+ and Br- ions. These values were compared with literature data for the association of H+ and Br- ions.
