A standard galvanic cell is constructed in which a Co2+ | Co half cell acts as the cathode. Which of the following statements are correct? Hint: Refer to a table of standard reduction potentials. (Choose all that apply.) The cathode reaction is Co2+ + 2e -> Co. Co is oxidized at the cathode. The anode compartment could be Fe³+|Fe²+. As the cell runs, anions will migrate from the Co²+ | Co compartment to the other compartment. In the external circuit, electrons flow from the Co²+ | Co compartment to the other compartment.
