Question

defination of electroefining of copper​

Answer 1

Answer:the apparatus used for electrolytic refining of copper consists of an electrolytic tank containing acidified copper sulphate solution as electrolyte(the copper sulphate solution is acidified by adding dilute sulphuric acid. a thick block of impure copper metal is made anode and a thin strip of pure copper metal is made cathode. on passing electric current, impure copper from the anode dissolve and goes into copper sulphate solution deposits on cathode. thus pure copper metal is produced on the cathode. the soluble impurities goes into the solution whereas insoluble impurities collect below the anode

Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal.
