Which of the following statements are correct? Hint: Refer to a table of standard reduction potentials. (Choose all that apply.) The anode compartment could be Br2|Br-. The anode reaction could be Al -> Al3+ + 3e-. In the external circuit, electrons flow from the Co2+|Co compartment to the other compartment. The cathode reaction is Co -> Co2+ + 2e-. As the cell runs, anions will migrate from the Co2+|Co compartment to the other compartment.
