    The data revealed that the anodic current in the 0.4 M MgS 2 O 3 electrolyte of pH 7.8 peaked at 0.217 V potential, showing a current as low as 5.79 A cm 2 for both reactions and even lower 4.46 A cm 2 for the gold anodic oxidation reaction alone. The latter value was calculated based on the gold electrode mass change during cyclic voltammetry which can be seen in Fig. 2.
