Abstract

he redox mechanisms were examined for Copper bromide in the absence and presence of (LC) using cyclic voltammetry. The mechanisms of reduction and oxidation were examined  while using new glassy carbon electrode prepared in laboratory from pure carbon piece jointed with copper wire and isolated by heat shrink polymer to avoid contact with solutions. In order to explain the type of the used reaction in electrochemical study, the complexation stability constants and Gibbs free energies of complex formation obtained from the interaction of CuBr2 with (LC) were obtained from the experimental part and their values were discussed. The prepared galssy carbon electrode was polished with Al2O3 andput in a woolen clear piece, washed and used for cyclic voltammetry measurements.
