Electrolysis of Molten NaCl

by

At temperature of 8010C, Sodium Chloride (NaCl) melts and separate into Sodium and Chloride ions.

Ions Formed After Dissociation

Compound

Anion

Cation

NaCl

Cl-

Na+

Migration of Ion

Cathode

Anode

Na+

Cl-

Discharge

Based on the ions present, Na+ will be discharged at the Cathode and Cl- will be discharged at the anode.

At cathode:  Na+  +  2e ------> Na(s)

At Anode:  Cl-  ------> Cl2(g) + 2e

Overall equation for reaction

Na+  +  Cl-   ------> Na(s)  +  Cl(g)

Product

Sodium will be produced at cathode and Chlorine gas will be produced at anode
