What Is the Half-Reaction That Occurs at the Cathode During

question 40

Multiple Choice

What is the half-reaction that occurs at the cathode during the electrolysis of an aqueous sodium iodide solution? Half-Reaction E° (V)
2H₂O(l) + 2e^- → H₂(g) +2OH^-(aq) -0.83
O₂(g) + 4H⁺(aq) + 4e^- →2H₂O(l) +1.23
Na⁺(aq) + e^- → Na(s) -2.71
I₂(s) + 2e^- → 2I^-(aq) +0.53

• A)Na⁺ + e^- →
• B)O₂(g)+ 4H⁺(aq)+ 4e^- → 2H₂O(l)
• C)2H₂O + 2e^- → H₂ + 2OH^-
• D)I₂ + 2e^- → 2I^-
• E)2I^- → I₂ + 2e^-
