AnswEr :

Sodium can be obtained from Sodium chloride from the process of electrolysis.

ExplaNation :

Molten Sodium chloride contains free Sodium ions \bf\ Na^+ and Chloride ions \bf\ Cl^- . During the electrolysis of molten sodium chloride the following reaction take place at the two electrodes :

(i)At cathode : \underbrace{2Na^+(Sodium \: ions)}_{from \: molten \: NaCl} + \underbrace{2e^-(Electrons)}_{from \: Cathode} \longrightarrow\underbrace{2Na(Sodium \: atoms)}_{Sodium \: metal}

Thus; Sodium metal is produced at the cathode.However, Chlorine can also produce in this reaction (at anode).

(ii) At Anode : \underbrace{2Cl^-(Chloride \: ions)}_{from \; molten \: NaCl} -  \underbrace{2e^-(Electrons)}_{Given \: to \; anode} \longrightarrow\underbrace{Cl_2}_{chlorine \: gas}

Thus, chlorine gas is formed at anode.

Note :

We cannot use an aqueous solution of Sodium chlroide to obtain Sodium.
