Question

to electrorefine an impure copper metal block, suggest the particular anode and the cathode to be taken and desribe in short the observation.​

Answer 1

Answer:

Electrolytic Refining of Copper. ... A block of impure copper is taken as an anode or positive electrode. Copper sulfate which is acidified with sulphuric acid is used as a graphite-coated electrolyte along with pure copper tubes, as a cathode or negative electrode.

Answer 2

Explanation:

In the Electrolytic refining method, the impure metal is made to act as anode. A strip of same metal in pure form is used as cathode. They are put in a suitable electrolytic bath containing soluble salt of same metal. The more basic metal remains in the solution and less basic ones go to the anode mud.

Copper is refined using an electrolytic method, anode of impure copper and pure copper strips are taken as cathode in the acidified copper sulphate solution. Impurities from the blister copper deposit as anode mud.
