The critical micelle concentration of aqueous solutions of barium, strontium, and nickel soaps was determined by conductivity measurements. The conductance behavior of soap solutions at various temperatures is exhibited by the equation log μ = A + B log C where A and B are constants and C is the concentration of soap in g moles/liter. The values of constant A were found to vary with temperature, whereas those of B were independent of temperature. Kraus and Bray’s type expression was used to evaluate molecular conductance at infinite dilution, dissociation constant K., and heat of dissociation. The results confirm that the critical micelle concentration remains unaffected by temperature in the range 35–50 C.
