The electrode process of the Cu(II)-ethylenedithioldiacetic acid chelatereduction occurs in two one-electron reduction steps. The reversibility of the first polarographic wave was confirmed by microcoulometry at constant potential. The second wave was found to be quasi-reversible unless the chelate forming agent is present in great excess. The kinetic parameters of these electrode processes were evaluated from the Koutecký and Matsuda-Ayabe theories. The value of activation energy at E=0 vs. NHE, was also found. The chronopotentiometric investigations of the same system gave resultswhich are in good agreement with those obtained polarographically.
