The kinetics of the oxidation of glyoxylic and pyruvic acids by periodate have been studied at pH 0–9 and 273–303 K. The kinetics are second order, first order in each reactant and the rate has a maximum at pH 6. It is suggested that the dehydrated periodate monoanion IO4– is the only reactive periodate species and the α-oxocarboxylic acids and their anions react in their dehydrated forms.
