On igniting \( Fe_2O_3 \) at \( 1400^\circ C \), the product obtained is ________.
Show Hint
On igniting $Fe2O3$ at $1400C$, the product obtained is ____.
Updated On: Apr 15, 2026
- $Fe_{2}O_{3}$ melt
- FeO
- $Fe_{3}O_{4}$
- metallic iron
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Process
Heating iron oxides to very high temperatures in the presence of reducing agents (like CO in a furnace) leads to reduction.
Step 2: Temperature Effect
At $1400^{\circ}C$, the reduction of iron oxides is completed. $3Fe_{2}O_{3} + CO \rightarrow 2Fe_{3}O_{4} + CO_{2}$ $FeO + CO \rightarrow Fe + CO_{2}$
Step 3: Conclusion
Igniting at this extreme temperature yields metallic iron.
Final Answer: (D)
