Abstract
The reduction of the Fe(III)-oxalate complex at a polycrystalline gold electrode from a solution of 1 M K 2C 2O 4+0.05 M H 2C 2O 4 has been studied by dc current and impedance measurements. The results indicate a multi-step mechanism of the CEC type, i.e. the electron transfer is preceded and followed by a heterogeneous chemical reaction. An EC mechanism (preceding reaction not present or fast) can also fit the experiments if the individual transfer coefficient of the electron-transfer step is allowed to be 0.4 instead of 0.5. The conclusions are compared with earlier results obtained at the dropping mercury electrode.
