Effect of Ionic Strength on the Kinetics of the Oxidation of Ascorbic Acid by Hexacyanoferrate(III): Comparison between Specific Interaction Theories and the Mean Spherical Approximation

Abstract

The influence of ionic strength on the rate constant of the oxidation reaction of ascorbic acid by hexacyanoferrate(III) in acidic medium is investigated. The dependence of the rate constant on ionic strength is discussed according to different specific interaction theories and the mean spherical approximation.
