A standard galvanic cell is constructed with Sn2+ | Sn and Cu2+ | Cu half cell compartments connected by a salt bridge. Which of the following statements are correct? (Choose all that apply.)

1. In the external circuit, electrons flow from the Cu2+|Cu compartment to the Sn2+|Sn compartment.
2. The anode compartment is the Sn2+|Sn compartment.
3. The cathode compartment is the Sn2+|Sn compartment.
4. As the cell runs, anions will migrate from the Cu2+|Cu compartment to the Sn2+|Sn compartment.
5. Cu2+ is reduced at the cathode.
