Q
Q: What is the primary role of carbon in the extraction of iron from its ore?
Solution:
Carbon acts as a reducing agent, reducing iron oxide to iron during the extraction process.
Steps: 7
Show Steps
Step 1: Understand that iron is found in nature as iron ore, which is mainly iron oxide.
Step 2: Know that iron oxide is a compound made of iron and oxygen.
Step 3: Learn that to extract iron from its ore, we need to remove the oxygen from iron oxide.
Step 4: Recognize that carbon is used in the extraction process, usually in the form of coke.
Step 5: Understand that carbon reacts with iron oxide at high temperatures in a furnace.
Step 6: Know that during this reaction, carbon takes the oxygen away from iron oxide, which is called reduction.
Step 7: Realize that after the reaction, we are left with pure iron and carbon dioxide gas.
