The ion which will be reduced first at the cathode has to be given. Concept Introduction: Electrochemical series: It is a decreasing order of the reduction potentials. The most positive E 0 are placed in the top in the electrochemical series; it has greater tendency for reduction and lower tendency of oxidation. And the most negative E 0 values of elements are placed in the bottom of the series.
