Abstract: The mixed-electrolyte model proposed recently by Shanks and Franses has been applied to estimate the critical micelle concentration, aggregation number, and counterion binding constant of cetyl pyridinium chloride from its measured conductance data in water at 25°C. The surface potential of this cationic micelle has been computed by solving the non-linearized Poisson-Boltzmann equation. The electrostatic, hydrophobic, and the overall free energies of the ionic micelle formation have also been calculated. The present study also envisages that ionic micelles do not contribute to the ionic strength of the surfactant solution.
