Abstract
The reduction and oxidation mechanisms for copper chloride were studied in 0.1M KBr in absence and presence of safranin (Saf) at 19.1°C.The mechanism of oxidation and reduction was examined. The effect of scan rate for the redox reaction of CuCl2 in absence and presence of safranin (Saf) was carried oue to explain the type of reactions for this electrochemical process. Thermodynamic parameters such as stability constants and Gibbs free energies for the complex formation of the interaction of CuCl2 with safranin (Saf) were evaluated and discussed.
