Abstract
The fast oxidation of ascorbic acid by Fe(III)benzohydroxamic acid com plex [Fe(BHA)(3)] has been investigated by the stopped-flow technique in aqueous ethanol medium at three pH values (4.6, 7.0, and 9.0). The reaction exhibits a first-order dependence of rate each on [ascorbic a cid] and [Fe(BHA)(3)], obeying Michaelis-Menton kinetics. The rate of the reaction was found to be pH-dependent.
