GIBBS ENERGY AND CONDUCTIVITY PROPERTIES OF NACL SOLUTIONS IN THE WATER PLUS N-PROPANOL MIXTURES AT 298.15 K

The electrical conductivity of NaCl solutions and the emf of the cell: glass electrode (Na)\NaCl\AgCl\ Ag in water + n-propanol mixtures have been measured at 298.15 K. The values of limiting molar conductances (Lambda(0)), Walden products (Lambda(0) eta), association constants (K-A) and parameters of distance of ions (R) were determined. Based on the emf data obtained, the Gibbs energies of transfer of NaCl (Delta(t)G(0)) were calculated, taking into account the ionic association of electrolyte. From literature data and those obtained in this paper the values of entropy of transfer (Delta(t)S(0)) were calculated. Some required data derived from the literature are also presented.
