Structure and hydrogen bonding in aqueous sodium chloride solutions using theoretical water model AB4: Effects of concentration

► Influence of sodium chloride concentration on molecular structure of water model AB4. ► Growth of the average coordination number of oxygen atoms. ► Reduction of hydrogen bonds population. ► The diffusion coefficients of Na+ and Cl− ions decrease with increasing concentration. ► AB4 model of water is valid and can be used in the theoretical studies of the aqueous solutions.
