Question

name the anode and cathode use in the electrolytic refining of impure copper metal.

Answer 1

in a acidicfield it is use, anose is a impure cooper and cathode is a strip of pure cooper on passing current pure cooper deposited on the cathode 

Answer 2

Anode: Impure cathode

Cathode: Pure copper

Electrolyte is Copper sulphate solution.

Explanation:

• As the battery is connected and the circuit is switched on, in the cathode copper is converted into copper ion.  

• This copper ion moves through the solution and gets deposit in the cathode where it is converted into pure copper by gain of electron. This cycle goes on and on.  

• The size of the anode gradually decreases and impurities settle at the bottom of the electrolyte container and is known as the anode mud. The cathode form pure copper.
