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.) Zn²+ | Zn could be the other standard half cell. The cathode reaction is 2H+ + 2e -> H₂ In the external circuit, electrons flow from the other compartment to the H* | H₂ compartment. The cathode reaction is H₂ -> 2H+ + 2e- Ag* |Ag could be the other standard half cell.
