Reactivity of metals
Question
- A. Reduction with carbon
- B. Electrolysis
- C. Thermal decomposition
- D. Displacement reactions
Answer
Electrolysis
Explanation
Metals that are more reactive than carbon cannot be extracted from their ores using carbon reduction; instead, electrolysis is required.
Common mistake
Misunderstanding Extraction Methods
Students often confuse the extraction methods for metals with their reactivity series position, thinking that all metals can be extracted using the same method.
To fix this, students should study the reactivity series and understand that more reactive metals require different extraction methods, such as electrolysis, while less reactive metals can be extracted using carbon reduction.
