A standard galvanic cell is constructed in which a H* | H2 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 H2 -> 2H* + 2e O In the external circuit, electrons flow from the other compartment to the H"|H2 compartment. O Mg²+|Mg could be the other standard half cell. O Br2|Br could be the other standard half cell. O The cathode reaction is 2H* + 2e -> H2
