Question

explain the process of refining of metal with the suitable example​

Answer 1

Explanation:

• The impure metal is used as an anode and the pure metal is used a cathode. ... Soluble salt from the same metal is used an electrolyte. When an electric current is passed, pure metal gets deposited at the cathode and the impure metal gets dissolved from the anode.

Answer 2

Hey friend..

Hope this will help u

Principle of method of Electrolytic refining-

Electrolytic refining is the process of refining impure metals by using electricity. In this process impure metal is made as the anode and a strip of pure metal is made the cathode. A solution of a soluble salt of the same metal is taken as the electrolyte.

Example- Copper can be purified by this way.

In electrolytic refining of copper, the electrolyte is a solution of acidified copper sulphate. The anode is impure copper, whereas the cathode is a strip of pure copper on passing electric current, pure copper is deposited on the cathode.
