The rates of oxidation of four α‐keto acids, glyoxylic, pyruvic, phenylglyoxylic, and 2‐oxobutyric acids by Cerium(IV) in H 2 SO 4 HaHSO 4 and H 2 SO 4 HClO 4 solutions, have been studied spectrophotometrically. The rate data suggest that CeSO 4 2+is the most reactive of the Cerium(IV)‐sulfate complexes present in the H 2 SO 4 NaHSO 4 and H 2 SO 4 HClO 4 systems. The oxidation reaction is proposed to be a one‐electron process with the rate‐determining step being the decomposition of a α‐ketoacid‐Cerium(IV) complex to a free radical and carbon dioxide through a transition state.
