An inhibition effect of PdCl₂ on the rate of oxidation of sugars, by alkaline hexacyano-ferrate(III) has been observed. The order of reactions in hexacyanoferrate(III) and OH^- is zero and unity, respectively, while that in sugars decreases from unity at higher sugar concentration. The kinetic data and spectrophotometric evidence support the formation of {Pd^II - (sugar)} and {Pd^II - sugar)₂} complexes and their resistance to react with Fe(CN)₆^3-.
