Electrolytic refining is used for
a) Copper, b) Zinc, c) Tin, d) Nickel

• A. a, b, c, d
• B. a, b
• C. a, c
• D. b, d

Answer 1

The correct option is A a, b, c, d

The metals produced by various reduction processes described above are not very pure. They contain impurities, which must be removed to obtain pure metals. The most widely used method for refining impure metals is electrolytic refining. Many metals, such as copper, zinc, tin, nickel, silver, gold, etc., are refined electrolytically. Thus, Option $A$ is correct
