Definition of ammonia
Ammonia gas can be defined as a colorless alkaline gas, which is produced by the body during the decomposition of organic substances during important metabolic processes. It is made of nitrogen and hydrogen, and its molecular formula is (NH3), and it has a pungent and distinctive odor. It is worth noting that when a person is exposed to ammonia gas, it irritates the skin, eyes, nose, throat, and lungs.[1]
Ammonia gas properties
physical properties
Among the most important physical properties of ammonia gas are the following:[2]
- Its boiling point is -33.35 ° C.
- The freezing point is -77.7 ° C.
- Its stereoscopic shape looks like a triple pyramid, in which nitrogen is bonded with three hydrogen atoms and a pair of unshared electrons.
- It is the best solvent for organic matter.
- Its molecules are linked together by a hydrogen bond.
Chemical properties
Among the most important chemical properties of ammonia gas are the following:[2]
- The combustion of ammonia produces nitrogen gas and water.
- Ammonia gas dissolves in water giving off heat, forming what is sometimes known as ammonium hydroxide.
- Alkali metals and earth metals are dissolved in liquid ammonia, forming a blue solution.
Ammonia gas uses
ammonia in fertilizer
The ammonia that is produced is often used in the fertilizer industry, where 90% of ammonia is used for this purpose, and farmers use fertilizers to maintain soil productivity, and it also helps to increase the levels of essential nutrients for crops, such as: zinc, selenium, and boron.[3]
Ammonia in household cleaning products
Ammonia is used as an ingredient in many household cleaning products. It is effective in removing household dirt and stains from animal fats and vegetable oils such as cooking grease. Because ammonia is quick to evaporate, They are used in a glass cleaning solution so that no traces remain.[3]
Ammonia in industrial uses
Ammonia is used as a refrigerant in HVAC equipment, and ammonia can be used in the manufacture of many products including plastics, explosives, fabrics, pesticides, dyes, rubber, paper, and foodstuffs, and it is also used in the pharmaceutical industry.[3]
