Abstract: Kinetics of oxidation of mercury(I) by iron(III)-2,2'-bipyridyl in the presence of microamounts of palladium(II) has been studied spectrophotometrically in aqueous nitric acid and methanol media. The reaction exhibits first order each in [iron(III)-2,2ʹ-bipyridyl ] and [palladium(II)] and zero order in [mercury(I). Increase in [HNO3] decreases the reaction rate. Added products do not have any significant effect on the reaction rate. A suitable reaction mechanism is proposed and the reaction constants of the different steps involved have been evaluated.
