1.	Explain how the electrolytic refining of copper is done?
Answer» The apparatus consists of elecrtolytic tank containing acidified copper sulpahte solution as elecrolytes.A thick block of impure metal is made anode.A thin strip of pure copper metal made as cathodeOn passing electicity Impure copper from the anode dissolves and goes in cuso4 solution and pure copper from the copper sulphate solution deposits on the cathode.The pure copper metal is produced at cathode.The soluble impurities goes into the solution where as insoluble impurities settle down at anode as anode mud.Thanks. Current is passed through the acid 5 copper sulphate solution. A strip of pure metal is made by cathode while impure metal is made the anode as the current is passed , pure metal from the cathode dissolves in the electrolyte ,the same amount of pure metal goes to the cathode and the impurities settle below below the anode and are known as anode mud.
