Question

Name and describe the most widely used method for refining impure metals?

Answer 1

1. The most widely used method for refining is electrolytic refining.
2. During the process, a strip of pure metal is utilized as the cathode, and impure metal is used as the anode.
3. One takes the appropriate electrolyte.
4. When current flows through an electrolytic cell, impurities dissolve and settle as the anode must, and metal ions are deposited at the cathode, making the thicker impure strip thinner and the thinner pure strip thicker.
