Question

What is electrorefining? Give atleast one example.

Answer 1

Answer:

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.

Explanation:

Answer 2

Electrorefining is a process in which materials, usually metals, are purified by means of an electrolytic cell. ... An electric current is passed between a sample of the impure metal and a cathode when both are immersed in a solution containing cations of the metal.

Example- Copper can be purified by this way.
