The Oxidation of Ascorbic Acid by Hexacyanoferrate(lll Ion in Acidic Aqueous Media Application of the Marcus CrossRelation Luis J. A. Mallins' and J. Barbosa da Ccsta lnstituto Superior de Engenharia de Coimbra. 3000 Coimbra, Portugal While theoretical aspects of the Marcus theory for elecThe kinetics of the oxidation of Lascorbic acid by ions have been investigated in strongly acidic media over a wide range of acidity. Two different mechanisms involving the monoascorbate anion, AH, the neutral molecule of ascorbic acid AH 2, and the protonated species AH 3, as well as the ion Fe(CN) 3 6, and the monoprotonated form HFe(CN) 2 oxidation of ascorbic acid by hexacyanoferrate
