The kinetics of hexachloroiridate (IV) oxidation of N-(2-acetamido) imino diacetic acid in aqueous perchloric acid solution at a constant ionic strength of 0:1 mol dm(-3) have been investigated spectrophotometrically. The reaction was found to be firstorder in [IrCl(6)2-, second-order in (ADA) and inverse fractional order with respect to (H+). Kinetic evidence for the formation of intermediate complexes between the substrate and iridium (IV) is presented. The activation parameters have been calculated and a tentative reaction mechanism consistent with the kinetics is discussed.
