Abstract The kinetics of oxidation of the cobalt(II) complexes, [Co II (ADA)- (H2O)3] and [Co II (ADA)(M)(H2O)2] 2-, (ADA = N-(2-acetamido) iminodi-acetic acid and M = Malonate) by periodate in aqueous acetate medium to cobalt(III) have been studied spectrophotometrically at 565 nm over the 25 – 40 o C range at pH = 4.99 and I = 0.50 mol dm -3 under pseudo first order condition by taking large excess of oxidant (IO4 -). The oxidation of [Co II (ADA)(H2O)3] by periodate in presence of Mn(II) catalyst was also studied. Also The kinetics of oxidation of the cobalt(II) complexes, [Co II (ADA)(Su)(H2O)] 2-and [Co II (ADA)(Ma)(H2O)] 2-, by periodate in aqueous medium to cobalt(III) have been studied spectrophotometrically at 565 nm over the 30 – 50 o C range at pH = 4.99 and I = 0.30 mol dm -3 under pseudo first order condition by taking large excess of oxidant (IO4 -) |
