Question

Explain the principle of the method of electrolytic refining of metals. Give one example.

✓

Answer

In this method, the impure metal is made to act as anode. A strip of the same metal in pure form is used as cathode. They are put in a suitable electrolytic bath containing soluble salt of the same metal. Pure metal is deposited at the cathode and impurities remain in the solution.For example: electro refining of Cu, Ag, Au.
