A standard galvanic cell is constructed with Cl 2 | Cl - and Co 2+ | Co half cel

Question

A standard galvanic cell is constructed with Cl2|Cl- and Co2+|Co 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.)

A) As the cell runs, anions will migrate from the Co2+|Co compartment to the Cl2|Cl- compartment.

B) Cl- is oxidized at the anode.

C) The anode compartment is the Cl2|Cl- compartment.

D) Co is oxidized at the anode.

E) In the external circuit, electrons flow from the Co2+|Co compartment to the Cl2|Cl- compartment.

Explanation / Answer

Co/Co^2+(aq) //Cl^-(aq) /Cl2(g)

Co/Co^2+ is oxidation half clle. Cl2|Cl- is reduction half cell. The electrons flow from anode to cathode.

D) Co is oxidized at the anode. >>>>answer

E) In the external circuit, electrons flow from the Co2+|Co compartment to the Cl2|Cl- compartment. >>>>answer

D,E statements are correct
