title: Stopped-flow kinetic investigation of the oxidation of ascorbic acid by iron (III) benzohydroxamic acid.
abstract: The fast oxidation of ascorbic acid by Fe(III)benzohydroxamic acid complex [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 acid] and [Fe(BHA)3], obeying Michaelis-Menton kinetics. The rate of the reaction was found to be pH-dependent.
