Question

Diagram of an electrolytic cell showing anode, cathode, and molten NaCl with reactions.

Accepted Answer

Anode: 2 Cl⁻ (l) → Cl₂ (g) + 2 e⁻
Cathode: Na⁺ (l) + e⁻→ Na (l)
Overall: 2 NaCl (l) → 2 Na (l) + Cl₂ (g)

Answer

Anode: Na⁺ (l) + e⁻→ Na (l)
Cathode: 2 Cl⁻ (l) → Cl₂ (g) + 2 e⁻
Overall: 2 NaCl (l) → 2 Na (l) + Cl₂ (g)

Answer

Anode: Na⁺ (l) + e⁻→ Na (l)
Cathode: Cl⁻ (l) → Cl (g) + e⁻
Overall: NaCl (l) → Na (l) + Cl (g)

Answer

Anode: Cl⁻ (l) → Cl (g) + e⁻
Cathode: Na⁺ (l) + e⁻→ Na (l)
Overall: NaCl (l) → Na (l) + Cl (g)
