Abstract
The conductance of the aqueous solutions of calcium butyrate in presence of added electrolytes (nitrates of aluminium, copper and ammonium) was measured at 40 ± 0.05°C. The values of the critical micelle concentration (CMC), molecular conductance at infinite dilution, degree of dissociation, dissociation constant, free energy change for dissociation process and free energy change for micellization have been calculated in presence of these additives. The results suggest that the soap behaves as a weak electrolyte in these solutions below the critical micelle concentration.
