The oxidation‐reduction kinetics of the ferrous‐ferric sulfate system have been measured on a stainless steel surface. The data completely support theoretical equations which describe the potential‐current relationships for such a system. The analysis applies to reversible electrodes and to corroding electrodes where the potential is determined by two intersecting activation over‐ voltage functions. Also, the analysis permits calculation of a number of electrochemical constants with a minimum number of experimental observations. The possibility of determining anode‐to‐cathode area ratios for corroding metals is discussed.
