Abstract
The electrochemical properties of Cu(II) ions were studied in 0.1 M KNO3 at a hanging mercury drop electrode using cyclic and convolutive voltammetry in addition to chronoamperometry and chronopotentiometry methods. The Cu(II) ions consumed two electrons in two steps to form monovalent Cu(I) ions and Cu metal followed by a process of amalgam formation. The rates of both electron transfer steps were found to be quasi-reversible. Digital simulation was used to verify the electrode pathway and to determine and confirm the electrochemical parameters of the reductive process of bivalent Cu(II) ions.
