The Oxidation of Pentaamminecobalt(III) complexes of a-Hydroxy acids and a-Amino acids by PMS has been studied in different Micellar medium. The Oxidation of free a-hydroxy acids and a-amino acids were also carried out under the same conditions for comparative purpose. On comparing these two substrates with PMS oxidation of a-hydroxy acids react faster than a-amino acids. In these reaction the rate of oxidation shows first order kinetics each in [Cobalt (III)] and [PMS].The reaction has followed by observing the decrease in the absorbance at 502 nm for Co(III) complex in a UV-visible spectrophotometer. Product and Stoichiometric analysis were carried out for the oxidation of complexes and free ligands in three different (Anionic, Cationic and Neutral) micellar medium with increasing micellar concentration an increase in the rate is observed. Among three different micelles Cationic micelle of Cetyltrimethylammonium bromide (CTAB) react faster than Anionic micelle of Sodium laurylsulphate(NaLS) and Neutral micelle of Triton. A Mechanism involving the one electron transfer for the complex and two electron transfer for the ligand was proposed.
