Question

Molten magnesium chloride is electrolyzed using inert electrodes and reactions represented by the following two half-reactions:
2Cl-(l)→Cl2(g) + 2e-
Mg2+(l) + 2e- →Mg(s)
Concerning this electrolysis, which of the following statements is true?
A) The anions in the electrolyte undergo reduction.
B) Mg2+ions are reduced at the anode.
C) Oxidation occurs at the cathode.
D) Electrons pass through the metallic part of the circuit from Mg2+ions to the Cl-ion.
E) Cl-ions are reducing agents.
