Hexacyanoferrate(III)/(II) system has been studied by UV‐visible long‐pathway spectroelectrochemistry. Three different methodologies, based on potentiodynamic techniques, have been successfully used in the thermodynamic characterization of the system. Formation of soluble Prussian Blue has been detected during the electrode process. The values of the formal potential ( E 0′ =0.200 V) and the electron stoichiometry of this side‐reaction ( n =0.5) have been obtained.
