The study includes oxidation of lactic, citric, tartaric, malic, mandelic, (alpha)-hydroxy isobutyric and isobutyric acids by sodium bismuthate as an oxidizing agent. The oxidation reactions were carried out in water, aqueous sulphuric (1-> 4N) or glacial acetic acid, using different molar proportions of sodium bismuthate. A tentative mechanism of oxidation is given and discussed.
