Question

Explain Electrolytic Refining Of Metals.

Answer 1

• Electrolytic refining is a technique used for the extraction and purification of metals that are obtained by refining methods.
• Pure metals are used as a cathode and impure metal is used as an anode.
• The same metal is used as an electrolyte.
• Example of electrolytic refining:
• At Cathode: ${\mathrm{Cu}}^{2+}+2{\mathrm{e}}^{-}\to \mathrm{Cu}$
• At Anode: $\mathrm{Cu}-2{\mathrm{e}}^{-}\to \mathrm{Cu}$

Therefore, Electrolytic refining is used for the extraction of Metals.
