however, when hydrochloric acid ( HCl ) is added to the same solvent mixture, as
shown in Fig. 4 (bottom). This shows that not only the ionic charge is important in
a DPD simulation but also the kind of ionic species in the mixture. This informa-
tion must be incorporated in the simulation using the a ij parameter because each
species has a different activity coefficient and the chemical potential is modified in
a different way.
