Solution

The correct option is D Both statements are true
Electrolytic refining is the most widely used method for the refining of impure metals obtained by various reduction processes. Copper and zinc are purified by electrolytic refining. So, statement 1 is correct.
During the refining of copper, copper sulphate solution forms the electrolyte, the anode is made of block of impure copper and cathode is made of thin strip of highly pure copper.
Hence, both the statements are true.
