explain electrolytic refining of copper
Answers
Answer:
ON PASSING ELECTRIC CURRENT ,IMPURE COPPER FROM THE ANODE DISSOLVES AND GOES INTO COPPER SULPHATE SOLUTION DEPOSIT ON CATHODE . THUS, PURE METAL IS PRODUCE ON THE CATHODE. THE SOLUBLE IMPURITIES GOES INTO SOLUTION AND FORM ANODE MUD.
Many metals like copper, zinc, tin lead are refined by this method. ... 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.
Answer:
In the process of electrolytic refining of copper, the electrolyte used is acidified copper sulphate. Impure metal is made as an anode and pure metal is made as a cathode. On passing the electric current through the electrolyte, the impure metal from anode dissolves into the electrolyte solution.
