WebAbstract. We introduce a mathematical model for the finite size (repulsive) effects in ionic solutions. We first introduce an appropriate energy term into the total energy that represents the hard sphere repulsion of ions. The total energy then consists of the entropic energy, electrostatic potential energy, and the repulsive potential energy. Web23 aug. 2024 · Ionic crystals are constructed by a regular orientation of the oppositely charged ions which are considered as hard sphere. The ions are held together by the strong electrostatic forces. Within the crystal in addition to the coulombic forces there is a short range repulsive force originated from the interpenetration of the electronic clouds.
