Abstract: | The molecular dynamics simulations have been performed for the sodium nitrate solution at various concentrations in the 1.1 mol% sodium chloride aqueous solution, which is a model of the sea water. The structure, the velocity correlation functions and the frequency-dependent diffusion coefficients have been obtained. The share viscosity has also been obtained at various concentrations using the Green–Kubo formula, which agrees well with the experimental data. The complex formation and the microscopic charge neutrality in the solution have been discussed in relation to the ionic conductivity estimated by the Nernst–Einstein relation. |
