Question

with the help of a labelled diagram explain the process of electroretining class 8.​

Answer 1

Answer:

Electrolytic refining is a technique that is used for the extraction and purification of metals that are obtained by refining methods. 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. Impurities from the metal gets collected below the anode and is known as anode mud.

Cu+2+2e–→ Cu

Answer 2

Answer:

Electrorefining is the process of purifying a metal, using electrolysis. In this process, salt solution of the metal to be purified is taken as an electrolyte solution and the metal to be purified is made anode. A rod of pure metal is made cathode.
