The reaction between pyridinium chlorochromate and As(III) was studied in hydrochloric acid medium. The reaction was found to be overall second order the added product As(V) was found to decrease the rate. The hydrogen ion was found to catalyse the reaction and it was predicted that both protonated and free pyridinium chlorochromate are active to a different extent. The active species of the reductant was H3AsO3 and the mechanism is discussed in terms of these species. The retardation by the added product is predicted to be due to a competitive ester formation.
