| Abstract: | ![]()
The rates of oxidation of Fe(II) in NaCl and NaClO4 solutions were studied as a function of pH (6 to 9), temperature (5 to 25°C), and ionic strength (0 to 6m). The rates are second order with respect to [H+] or [OH–] and independent of ionic strength and temperature. The overall rate of the oxidation is given by
