Ionic Distribution Coefficients and Electrochemical Potentials

Abstract

A novel “electrochemical ionic distribution coefficient”, i is defined based on Guggenheim's electrochemical potential concept. i correlates the activities of a given ion in different solvents. The definition of i is entirely consistent with the practice to interrelate chemical equilibrium constants in various solvents via the classical ionic distribution coefficient i.

Key Words:

• Distribution coefficients
• partition coefficients
• medium effects
• electrochemical potential
• pH scales in different solvents.
