A standard galvanic cell is constructed with I2|I- 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.) The anode compartment is the Mg2+|Mg compartment. Mg2+ is reduced at the cathode. As the cell runs, anions will migrate from the I2|I- compartment to the Mg2+|Mg compartment. In the external circuit, electrons flow from the I2|I- compartment to the Mg2+|Mg compartment. The anode compartment is the I2|I- compartment.
