Electrolyte volumetric properties reveal ion-solvent interactions. Solvation numbers and electrostriction effects are key to understanding ion behavior in solutions, with implications for ion pairing.

Area of Science:

  • Physical Chemistry
  • Solution Chemistry
  • Thermodynamics

Background:

  • Volumetric properties of electrolytes offer insights into ion-solvent and ion-ion interactions.
  • Standard partial molar volume at infinite dilution (V(infinity)(salt)) reflects interactions with the solvent.
  • Splitting V(infinity)(salt) into ionic contributions (V(infinity)(ion)) requires extra-thermodynamic assumptions.

Purpose of the Study:

  • To determine ionic contributions to volumetric properties.
  • To quantify solvent electrostriction and solvation numbers.
  • To investigate the phenomenon of ion pairing in electrolyte solutions.

Main Methods:

  • Density measurements to obtain standard partial molar volumes.
  • Continuum solvent model for iterative shell-by-shell calculations.

  • Analysis of the pressure derivative of the association constant for ion pairing studies.

    • Main Results:

    • Calculated V(infinity)(ion)(calc) show good agreement with experimental values for univalent ions.
    • Electrostriction (DeltaV(el)(ion)) and molar electrostriction of solvent (DeltaV(el)(S)) are calculable and negative.
    • Solvation number (n(infinity)) is determined by the ratio of ionic to solvent electrostriction.
    • Ion pairing effects (DeltaV(ip)) and associated solvent release (Deltan(ip)) are quantifiable.

    Conclusions:

    • The study provides a method to calculate and compare ionic partial molar volumes and solvation numbers.
    • Electrostriction plays a crucial role in the volumetric behavior of ions in solution.
    • The framework allows for the investigation of ion pairing and its impact on solvent structure.
