Abstract
Conductance measurements are reported for Bu 4 NCl, Bu 4 NBr, Bu 4 NI, and Bu 4 NClO 4 at 30°C in water-sulfolane mixtures over the entire solvent composition range. Experimental data were analyzed by the 1965 Fuoss-Onsager-Skinner equation. The limiting equivalent conductances in water and in sulfolane were compared with literature values. The trends of the Walden products are discussed in terms of water structural changes caused by addition of sulfolane. As expected, on the basis of previous results reported in the literature, a significant amount of association was detected for Bu 4 NI in water. Very small association constants were also found for Bu 4 NI and Bu 4 NClO 4 at 10 wt.% sulfolane.
