Answer 1

Answer:

ExpUnlike aluminum, copper metal is fairly easy to obtain chemically from its ores. But by electrolysis, it can be refined and made very pure—up to 99.999%. Pure copper is important in making electrical wire, because copper's electrical conductivity is reduced by impurities. These impurities include such valuable metals as silver, gold and platinum; when they are removed by electrolysis and recovered, they go a long way toward paying the electricity

refining of copper electrolytic. refining is a process of obtaining pure metal by the process of electrolysis in this method an electric. ... an impure copper rod as anode in a thin sheet of pure copper as cathode in an electrolytic cell containing. an acidified solution of copper sulfate as electrolyte.

Electrolytic Refining means refining by electrolysis.

Many metals like copper, zinc, tin lead are refined by this method.

Process Of electrolytic Refining :

--> The apparatus consist of Electrolytic tank containing acidified copper sulphate solution as electrolyte.

--> A thick block of impure copper metal is made anode .

---> A thin strip of pure copper metal is made as cathode.

On passing electricity, Impure copper from the anode dissolves and goes into CUSO4 solution and pure copper from the copper sulphate solution deposits on the cathode .

Thus pure copper metal is produced at cathode . The soluble impurities goes into the solution whereas insoluble impurities settles down at anode as anode mud.

Chemical reaction :

 At cathode : Cu²⁺ + 2e  ---->Cu

At anode : Cu - 2e---->Cu²⁺
