The iron-chromium redox battery makes use of the reaction Cr2+ (aq) + Fe3+ (aq) 6 Cr3+ (aq) + Fe2+ (aq) occurring at a chromium anode and an iron cathode. Draw and label a cell diagram for this battery. Note: When all reactants and products are aqueous, use inert electrodes. Calculate the theoretical voltage of the battery.
