Abstract: The electrochemical behaviour for CuBr2 was studied in 0.1M KBr in absence and presence of different oxalic acid concentrations as ligand. The mechanism for the reduction and oxidation for CuBr2 in absence and presence of oxalic acid ligand were examined. The scan rates were done for the redox reaction of CuBr2 in absence and presence of oxalic acid for explanation of the type for the electrochemical reaction under consideration. Stability constants and complexation Gibbs free energies for the interaction of CuBr2 with oxalic acid were evaluated from the experimental part and their values were discussed.
