What does the term 'anhydrous ammonia' refer to?

• A. Ammonia with water.
• B. Ammonia mixed with oil.
• C. Ammonia without water.
• D. Ammonia under pressure.

Answer: (C)

The term 'anhydrous ammonia' specifically refers to ammonia that is free of water, hence the prefix 'an-' which means 'without.' This pure form of ammonia is often used as a refrigerant in cooling systems and as a fertilizer in agriculture. Its lack of water distinguishes it from other forms of ammonia, which may contain water or be in a diluted solution. Understanding this definition is important for recognizing the applications and handling requirements of anhydrous ammonia, especially in contexts where purity and potential hazards are concerns.
