A standard galvanic cell is constructed with Sn 2+ | Sn and Cr 3+ | Cr half cell

Question

A standard galvanic cell is constructed with Sn2+ | Sn and Cr3+ | Cr half cell compartments connected by a salt bridge. Which of the following statements are correct?

(Choose all that apply.)

A) Sn2+ is reduced at the cathode.

B) In the external circuit, electrons flow from the Sn2+|Sn compartment to the Cr3+|Cr compartment.

C) The anode compartment is the Sn2+|Sn compartment.

D) As the cell runs, anions will migrate from the Sn2+|Sn compartment to the Cr3+|Cr compartment.

E) The cathode compartment is the Sn2+|Sn compartment.
