Question

Which of the following electrolysis process is used for purification of pb?

• A. Hall process
• B. Parke's process
• C. Betts electrolysis process
• D. None of these

Answer 1

Answer: (C)

Betts electrolysis process

The Betts electrolytic process is an industrial process for purification of lead from bullion. Lead obtained from its ores is impure because lead is a good solvent for many metals. Often these impurities are tolerated, but the Betts electrolytic process is used when high purity lead is required, especially for bismuth-free lead.

Hence, the correct option is (C).
