O₂(g)+ 4 H⁺(aq)+ 4 E^-→ 2 H₂O(l)E° = +1

Multiple Choice

O₂(g) + 4 H⁺(aq) + 4 e^-→ 2 H₂O(l) E° = +1.23 V I₂(s) + 2 e^- → 2 I^-(aq) E° = +0.54 V
2 H₂O(l) + 2 e^- → H₂(g) + 2 OH^-(aq) E° = -0.83 V
Mg²⁺(aq) + 2 e^- → Mg(s) E° = -2.37 V
Based on the data above,electrolysis of an aqueous solution of MgI₂,with inert electrodes,is expected to produce

A) Mg at the cathode and I₂ at the anode.
B) H₂ at the cathode and I₂ at the anode.
C) Mg at the cathode and O₂ at the anode.
D) H₂ at the cathode and O₂ at the anode.
