  Isothermal-isobaric molecular dynamics simulations are used to examine the
microscopic structure and other properties of a model solution consisting of
NaCl salt dissolved in water-methanol mixture. The SPC/E water model and the
united atom model for methanol are combined with the force field for ions by
Dang [J. Amer. Chem. Soc., 1995, 117, 6954] to describe the entire system. Our
principal focus is to study the effects of two variables, namely, the solvent
composition and ion concentrations on the solution's density, on the structural
properties, self-diffusion coefficients of the species and the dielectric
constant. Moreover, we performed a detailed analysis of the first coordination
numbers of the species. Trends of the behaviour of the average number of
hydrogen bonds between solvent molecules are evaluated.
