Effect of hydrogen bond, relative permittivity and temperature on the transport properties and the association behavior of some 1:1 electrolytes in some binary mixed solvents

Effect of hydrogen bond, relative permittivity and temperature on the transport properties and the association behavior was studied through the measurements of the specific conductance of sodium acetate, sodium propionate and sodium salicylate in 10%, 20% and 30% (w/w) methanol–water (MeOH–H2O), ethanol–water (EtOH–H2O) and glycerol–water (GlyOH–H2O) mixtures at different temperatures (293, 298, 303 and 308K). The conductivity data have been analyzed using the Lee–Wheaton conductivity equation. The molar conductance (Λ), limiting molar conductance (Λ0), association constants (KA), Walden product (Λ0η0), hydrodynamic radii (RH), fluidity ratio(R), the activation energy of the transport process (Ea) and standard thermodynamic parameters of association (∆GA, ∆HA and ∆SA) were calculated and discussed.
