Conductance studies in mixtures of water with DMF at 298.15 K. Part VI. Lithium and sodium nitrates, sodium perchlorate and propionate, potassium picrate and thiocyanate, and limiting ionic conductance.

Conductance data of LiNO3, NaNO3, NaClO4, C2H5COONa, KPic, and KSCN in mixt ures of water with N,N-dimethylformamide (DMF), in the whole range of the m ixed solvent composition at 298.15 K, are reported. The obtained data have been analysed by the Fuoss-Justice equation in terms of the limiting molar conductance (Lambda(0)), ionic association constants (K-A), Walden products (Lambda(o)eta), and parameter R. From the data obtained here and those rep orted earlier, individual limiting ionic conductance of the anions of, NO3- , ClO4-, SCN-, Pic(-) and C2H5COO-, has been determined using Fuoss-Hirsch split. From the values of the individual limiting ionic conductance (lambda (0)(-)) obtained in this manner, the values of the Walden products for sing le ions (lambda(0)(-)eta) were also calculated. The obtained results as wel l as the values of the limiting molar conductance and Walden products for i ndividual ions have been discussed. Some literature data have also been pre sented for comparison. (C) 1999 Elsevier Science B.V. All rights reserved.
