ABSTRACT

Conductometric investigations on praseodymium soaps (myristate and palmitate) were performed at various temperatures (25°C, 30°C, 35°C, 40°C) and concentrations in a 60/40 benzene-methanol mixture (V/V). The critical micelle concentrations (CMC) obtained at different temperatures showed reasonable consistency with the CMC values derived from other physical measurement techniques. The molar conductance results indicated that praseodymium soaps in the 60/40 benzene-methanol mixture (V/V) act as weak electrolytes in dilute solutions, so the dissociation of these soaps can be understood through Ostwald's dilution law. Various thermodynamic parameters for both the dissociation and micellization processes were evaluated. The thermodynamic findings suggest that the micellization process is favored over the dissociation process.
