A novel approach to study ascorbic acid oxidation using hexavalent chromium species—theoretical and practical perspectives of the use of potentiometric titration technique
Year: 2024
Type: article
Abstract: This paper highlights the advantages of using the potentiometric titration technique as a valuable tool for studying the oxidation reaction of ascorbic acid by chromium(VI) in aqueous solutions. Particular attention was paid to the method of determining diagnostic points allowing the quantification of ascorbic acid in the sample under study. Additionally, the influence of experimental conditions, specifically the pH of the system and the concentration of the reactants, on the type of Cr(VI) species involved in the interaction with ascorbic acid was analysed. It has been shown that the method presented provides a simple, cost-effective and rapid tool that can be widely used for the direct determination of ascorbic acid.
