Oxidation reactions of L-ascorbic acid by three hexacyanometalate(III) ions in aqueous acidic media are studied at elevated pressures. Kinetic parameters characterizing two parallel paths involving ascorbic acid (H[sub 2]Asc) and ascorbate ion (HAsc[sup [minus]]) were reported. The reaction mechanism was discussed on the basis of the volume profiles of the redox reactions between ascorbic acid and hexacyanometalate ions.
