The molar conductances of NaOAc in 10-100 wt.% aqueous MeOH at 278.2, 288.2, 298.2, 308.2 and 318.2K were determine The four groups of best fitting parameters, such as the limiting molar conductance, L0, the ions association constant, KA, and the distance parameter, R (or a), were evaluated from Fuoss-Onsager-Skinner, Pitts, Lee-Wheaton and Fuoss-1978 conductance equations, resp. A discussion about the applicability of the four conductance equations, the dependence of L0, KA, the Walden product, L0h, and the ion-solvent interactions on temperature and the wt.% of MeOH in the systems are given.
