Metal oxides are reduced to metal by:
Metal oxides are reduced to metal by:
- A. electrolytic reduction
- B. liquation
- C. distillation
- D. none of the above
Step-by-step solution
Metal oxides are reduced to metals by removing oxygen. Electrolytic reduction is a common method, especially for active metals like aluminum, where an electric current is passed through a molten oxide to reduce it. Liquation is a purification method for low-melting metals, and distillation is used for volatile metals, not directly for reducing oxides. Therefore, electrolytic reduction is the correct choice.
