Question

A standard galvanic cell is constructed with Zn^2+|Zn and Mg^2+ | Mg half cell compartments connected by a salt bridge. Which of the following statements are correct? (Choose all that apply.) As the cell runs, anions will migrate from the Zn^2+ Zn compartment to the Mg^2+ Mg compartment. The cathode compartment is the Zn^2+ Zn compartment. The cathode compartment is the Mg^2+ Mg compartment. In the external circuit, elections flow from the Zn^2+ Zn compartment to the Mg^2+ Mg compartment. Mg is oxidized at the anode.

Explanation / Answer

Since the oxidation potential of Mg is very much higher than Zn

Hence at the oxidation side, Mg will be getting oxidised to Mg(+2) and at the reduction side, Zn(+2) will be getting reduced to Zn(s)

Oxidation Cell

Mg(s) -----------> Mg(+2)(aq) + 2e-

Reduction Cell

Zn+2(aq) + 2e- ---------- Zn(s)

Net Reaction

Mg(s) + Zn+2(aq) ---------- Mg+2(aq) + Zn(s)

The B is correct answer, since zinc reduction will take place at cathode

The E is the correct answer, since Mg is getting oxidized at anode

BE are the correct answer
