A standard galvanic cell is constructed in which a Cu2+ Cu 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.)
A) The cathode reaction is Cu -> Cu2+ + 2e-.
B) The anode compartment could be F2|F-.
C) In the external circuit, electrons flow from the Cu2+|Cu compartment to the other compartment.
D) As the cell runs, anions will migrate from the Cu2+|Cu compartment to the other compartment.
E) The cathode reaction is Cu2+ + 2e- -> Cu.
