| Abstract: | Considered the interactions among all charged colloidal particles, derived a symmetrical Poisson Boltzmann (PB) Equation using a Virial Expansion of Ornstein Zernike Equation. Calculated the electrostatic and internal potential energies of charged colloidal particles positively and the ions of 1 1 electrolytes in the medium by the deduced symmetrical PB equation. Those potential energies were compared with that provided by the Poisson Boltzmann Equation. |
