Densities of solutions of NaCl and CsCl in mixtures of water and methanol
are determined by experiment and molecular dynamics simulation. Both experiments
and simulations cover the concentration range up to the solubility
limit of the salt in the temperature range 288.15 ? T / K ? 318.15 at ambient
pressure. Non-polarizable molecular models from the literature are used
for the ions and solvents. The partial molar volume of the salts at infnite
dilution in the mixed solvent is determined from an empirical correlation of
the data. The mixed solvent effects on the density and the partial molar
volumes of the salts are well predicted by the molecular models.
