This paper reports experimental data for the solution and polarisation resistances, exchange-current density, and rate constant of the Fe2+/Fe3+ redox couple. To use this couple in redox batteries, it is concluded that the concentrations of Fe'+must be greater than 0.4 M and that of the supporting H
