Potential of mean force between ions in infinitely diluted simple short-range models of aqueous electrolytes
As an attempt to assess the effect of the long-range electrostatic interactions in solutions of electrolytes, a simple short-range model (SSM) of electrolytes made up of primitive water and primitive ions (i. e., ions whose Coulombic interaction with water has been replaced by a triangular-well...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | As an attempt to assess the effect of the long-range electrostatic interactions
in solutions of electrolytes, a simple short-range model (SSM) of
electrolytes made up of primitive water and primitive ions (i. e., ions whose
Coulombic interaction with water has been replaced by a triangular-well
interaction) has been considered to compute the potential of mean force.
The sizes of the primitive ions have been set so as to approximate realistic
NaCl, LiI, and CsCl electrolytes. It is shown that despite the missing longrange
Coulombic interaction the model captures the basic features of real
electrolytes while the indirect, i.e. water mediated, potential of mean force
in the SSM is in qualitative agreement with that of realistic models. |
