Question 7

Multiple Choice

The figure shows the electrolysis of molten AlCl3. What reaction occurs at the anode of this cell? The figure shows the electrolysis of molten AlCl<sub>3</sub>. What reaction occurs at the anode of this cell? A) AlCl<sub>3</sub>(l) → AlCl<sub>2</sub>(l) B) Cl<sup>-</sup>(l) + e<sup>- </sup>→ Cl<sup>2-</sup> C) Al<sup>3+</sup>(l) + 3e<sup>-</sup> → Al(l) D) 2Cl<sup>-</sup>(l) + 2e<sup>-</sup> → Cl<sub>2</sub>(g) E) 2Cl<sup>-</sup>(l) → Cl<sub>2</sub>(g) + 2e<sup>-</sup>


A) AlCl3(l) → AlCl2(l)
B) Cl-(l) + e- → Cl2-
C) Al3+(l) + 3e- → Al(l)
D) 2Cl-(l) + 2e- → Cl2(g)
E) 2Cl-(l) → Cl2(g) + 2e-
