Question

Which reducing agent is used for the extraction of highly reactive metal from their ores ?

• A. CO₂
• B. CO
• C. Electricity
• D. Carbon

Answer 1

Answer:

C. Electricity

• Highly reactive metals (like Sodium, Potassium, Calcium, Magnesium, and Aluminum), which are at the top of the reactivity series, form very stable compounds (like oxides and chlorides).

• To extract these metals from their ores, a strong reducing agent is required. Common chemical reducing agents like Carbon (C) or Carbon Monoxide (CO) are not powerful enough to reduce the stable compounds of these metals.
