Ammonia vs. Ammonium Nitrate: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on December 25, 2023
Ammonia is a colorless gas with a pungent smell; Ammonium Nitrate is a solid, crystalline compound used as a fertilizer.
Key Differences
Ammonia (NH3) is a colorless, pungent gas, commonly used in cleaning products and as a building block in the production of fertilizers. Ammonium nitrate (NH4NO3), on the other hand, is a solid compound that serves primarily as a high-nitrogen fertilizer, offering a steady supply of nitrogen to plants.
In its natural form, ammonia exists as a gas and is highly soluble in water, forming ammonium hydroxide. Ammonium nitrate is a crystalline powder that is soluble in water, widely used for its high nitrogen content, which is essential for plant growth.
Ammonia is produced naturally by bacteria in soil and is an important component of the nitrogen cycle. Ammonium nitrate is manufactured by combining ammonia with nitric acid and is often used in agriculture to improve soil fertility.
The production of ammonia is a key industrial process, typically achieved through the Haber-Bosch process. Ammonium nitrate, in addition to its agricultural uses, has also been used in mining and construction for explosives due to its high nitrogen content and ease of detonation under certain conditions.
Ammonia, due to its strong odor, is also used in industrial refrigeration systems. Conversely, ammonium nitrate, because of its high solubility and hygroscopic nature, requires careful storage to prevent moisture absorption and decomposition.
