    • Although we have tried to solve the integral equation with ions of ±2e, we found that the concentration fluctuation at low wave number increased to diverge with increasing the ionic charge. The divergence of long wavelength concentration fluctuation suggests the phase instability, and we cannot say at present whether the ionic models or the theoretical approximations are responsible to the unexpected instability

    • The dielectric constant required in the DRISM/HNC calculation involves only the correlations between solvent molecules. On the other hand, both the ions and solvents response to the external electric fields, and the contribution of the solvent cannot be determined by the static or low-frequency measurements due to the large conductive response of ions. An experimental method to extract the response of solvent is the relaxation measurement, where the separation of the contributions of solvent and ion is performed according to the difference in the relaxation times. Theoretical and computational studies performed by Chandra et al, show that the dielectric constant determined by the relaxation method is determined almost exclusively by the static correlation between solvent molecules in the cases of simple model systems, A.
