Abstract:

An MD simulation of an 18,5 model LiCl aqueous solution was performed with the flexible Bopp-Jancsó-Heinzinger model for water, ion-water pair potentials derived from ab initio calculations and the ion-ion interactions described by a potential of Born-Mayer-Huggins (BMH) type. The comparison with a simulation of the same system, where the ion-ion interactions were described by a (12-6) Lennard-Jones + Coulomb a potential, demonstrates that such a change affects not only the ion-ion but also the ion-water radial distribution functions significantly, and that the results with the BMH potential conform better to X-ray results. The self-diffusion coefficients for water and the ions are found to be lower by almost one order of magnitute compared with dilute solutions.
