A standard galvanic cell is constructed with Cr3+ | Cr2+ and Mg2+ | Mg 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. The cathode compartment is the Mg2+ | Mg compartment. As the cell runs, anions will migrate from the Mg2+ | Mg compartment to the Cr3+1 Cr2+ compartment. The cathode compartment is the Cr³+ | Cr²+ compartment. In the external circuit, electrons flow from the Mg2+ |Mg compartment to the Cr3+1 Cr2+ compartment.
