What is electrolytic reduction?

Verified Answer

Electrolytic reduction is a chemical process in which a substance gains electrons (reduction) during electrolysis.

Explanation:

  • In electrolysis, an electric current is passed through a molten or aqueous compound
  • Reduction takes place at the cathode (negative electrode)
  • Positive ions (cations) move toward the cathode and gain electrons

Example:
Extraction of metals like aluminum from aluminum oxide (Al₂O₃):
Al³⁺ + 3e⁻ → Al

Key points:

  • It is used for extracting highly reactive metals
  • Occurs at the cathode during electrolysis
  • Involves gain of electrons

Electrolytic reduction is widely used in metallurgy and industrial processes.
