Question
A standard galvanic cell is constructed with Br2 | Br- and Cl2 | Cl- half cell compartments connected by a salt bridge. Which of the following statements are correct? (Choose all that apply.)
A. As the cell runs, anions will migrate from the Cl2|Cl- compartment to the Br2|Br- compartment.
B. The cathode compartment is the Cl2|Cl- compartment.
C. In the external circuit, electrons flow from the Cl2|Cl- compartment to the Br2|Br- compartment.
D. Br2 is reduced at the cathode.
E. Cl2 is reduced at the cathode.

A standard galvanic cell is constructed in which a H+ | H2 half cell acts as the cathode. Which of the following statements are correct?
(Choose all that apply.)
A. The anode compartment could be F2|F-.
B. As the cell runs, anions will migrate from the other compartment to the H+|H2 compartment.
C. In the external circuit, electrons flow from the other compartment to the H+|H2 compartment.
D. H2 is oxidized at the cathode.
E. H+ is reduced at the cathode.
