Abstract
Kinetic and spectroscopic evidence is reported for the formation of an intermediate Fe(III) oxalate-ascorbate complex during the oxidation of L-ascorbic acid by trisoxalatoferrate(III). The kinetic data for the formation of the intermediate are characteristic of a substitution-controlled process, and exhibit an inverse acid-concentration dependence. This is followed by a relatively slow innersphere electron- transfer reaction which is independent of pH, ascorbic acid concentration, and ionic strength. A detailed discussion of the kinetic data and a comparison with closely related oxidation reactions are presented.
