Question:
Ammonia is dried over ________.
Ammonia is dried over ________.
Show Hint
Ammonia is dried over ____.
Updated On: Apr 15, 2026
- slaked lime
- calcium chloride
- phosphorus pentoxide
- quick lime
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Chemical Nature
Ammonia ($NH_{3}$) is a basic gas.
Step 2: Analysis of Agents
- $CaCl_{2}$ reacts with $NH_{3}$ to form an addition compound ($CaCl_{2} \cdot 8NH_{3}$).
- $P_{2}O_{5}$ (acidic) reacts with $NH_{3}$ (basic).
- Quick lime (CaO) is basic and does not react with $NH_{3}$.
Step 3: Conclusion
Quick lime is the suitable drying agent.
Final Answer: (D)
