Conductance Studies of NaCl, KCl, NaBr, NaI, NaBPh4, and Bu4NI in Water+2-Ethoxyethanol Mixtures at 298.15 K
The electrical conductances of sodium chloride (NaCl), potassium chloride (KCl), sodium bromide (NaBr), sodium iodide (Nal), sodium tetraphenylborate. (NaBPh4), and tetrabutylammonium iodide (Bu(4)Nl) in water (1) + 2-ethoxyethanol (2) mixtures containing (0.01, 0.025, 0.05, 0.075, 0.10, 0.15, and 0.20) mol fractions of 2-ethoxyethanol have been measured at 298.15 K. The conductance data have been analyzed by the Fuoss-Justice equation. The individual limiting ionic conductivities of Na+, K+, Bu4N+, BPh4(-), I-, Cl-, and Br- ions have been determined using the Fuoss-Hirsch assumption. The dependencies of the limiting molar conductances, Lambda(o), and Walden products, Lambda(o)eta, versus mixed solvent composition have been discussed.
