Question

what is meant by electrolytic reduction? how is sodium obtained from its molten chloride? explain.

Answer 1

The electrolytic reduction is brought about by passing the electric current through molten salt. This process is also called as Electrolysis.
The highly reactive metals like K, Na,Ca, And Mg are extracted by the electrolysis of Their molten chlorides.
Extraction of sodium Metal:
sodium Metal is extracted by electrolytic reduction of molten sodium chloride.
when electric current is passed through molten chloride, it decomposes to form sodium metal and chlorine gas,
2NaCl (l)------------> 2Na(s)  + Cl₂(g)
           electrolysis

Answer 2

Answer:
