Answer 1

Answer:

What is meant electrolytic reduction ? How sodium is obtained from molten chloride ? Explain.

Explanation:

Metals are obtained from their molten chlorides by the process of electrolytic reduction. ... When an electric current is passed through it, then the electrolyte separates into its ions i.e. sodium ions and chloride ions.

Answer 2

Answer:

Electrolytic reduction is the process of obtaining pure metal from its impure form or ore through reduction by electrolysis.

Sodium is obtained from molten chloride by the following steps:

• Fused sodium chloride is taken as the electrolyte.
• Two electrodes are inserted into it.
• When an electric current is passed through it, then the electrolyte separates into its ions i.e. sodium ions and chloride ions.  
• Sodium ions migrate towards the cathode where they get reduced by gaining an electron, and thus sodium metal gets deposited at the cathode.  
• From the cathode we can easily obtain sodium metal.
• The impurities are deposited near anode as anode mud.
