Abstract

The thermodynamic properties of microemulsions and kinetic stability of water-oil (W/O) microdroplets were determined by Poisson-Boltzmann equation and ideal mixing assumption. The degree of dissociation depended on the competition between the entropy associated with counterions and surfactant ions. The results showed dependence of free energy change on dissociation which was hindered due to solubilization.
