Question
What is the role of carbon in the extraction of metals that are less reactive than itself?
Answer
Carbon acts as a reducing agent in the extraction of metals less reactive than itself by reacting with the metal oxides. During this process, carbon removes oxygen from the metal oxide, allowing the metal to be liberated.
Explanation
This question assesses the student's understanding of the reduction process and the role of carbon in metal extraction. It requires them to explain the chemical interaction between carbon and metal oxides.
Common mistake
Misunderstanding Reactivity and Extraction
Students often think that all metals can be extracted from their ores using carbon, regardless of their reactivity.
Remember that only metals less reactive than carbon can be extracted from their oxides by reduction with carbon. More reactive metals require different extraction methods.
