SAQ : Give the cathode anode reaction during the electrolysis of molten NaCl

Question

Give the cathode anode reaction during the electrolysis of molten NaCl. 

Answer

Cathode: Na⁺ + e^– → Na

Anode: 2Cl^– →  Cl₂ (g) + 2e^–

At the cathode, sodium ions are reduced to form sodium metal, while at the anode, chloride ions are oxidized to form chlorine gas.
