Kinetic Approach to the Mechanism of Oxidation of L-Ascorbic Acid by Periodate Ion in Acidic Medium
The aim of this study is to investigate the mechanistic pathway of the oxidation of L-ascorbic acid by periodate ions in acidic medium reaction. The oxidation of L-ascorbic acid (H2A) by periodate ions in acidic medium has been investigated under pseudo-first order conditions at 27 ± 0oC, [H+] = 1.0 x 10-3mol dm-3, I= 1.0 mol dm-3 (NaCl) and λ max 430nm. The stoichiometry of the reaction was observed to be 2:7 in terms of mole ratio of periodate ions and ascorbic acid consumed. The reaction is first order in both reactants and shows dependence on acid concentration.
