A standard galvanic cell is constructed with Fe3+ | Fe2+and Cr3+ | Cr half cell compartments connected by a salt bridge. Which of the following statements are correct? Hint: Refer to a table of standard reduction potentials. (Choose all that apply.) Cr3+ is reduced at the cathode. As the cell runs, anions will migrate from the Cr3+|Cr compartment to the Fe3+|Fe2+compartment. Fe3+ is reduced at the cathode. The anode compartment is the Cr3+|Cr compartment. In the external circuit, electrons flow...
