Ammonia is a compound of nitrogen and hydrogen with the chemical formula NH3. It is a colorless gas with a distinctive pungent smell. Ammonia is a crucial substance in both environmental and industrial contexts. In nature, it is produced by the decomposition of organic matter and is a vital component of the nitrogen cycle, playing a key role in the synthesis of amino acids in living organisms. Industrially, ammonia is primarily manufactured using the Haber-Bosch process, which synthesizes ammonia from nitrogen and hydrogen gases under high pressure and temperature in the presence of a catalyst. It is widely used as a nitrogen fertilizer in agriculture, which is its largest application. Additionally, ammonia is employed in the production of plastics, explosives, textiles, and dyes, and as a refrigerant in cooling systems due to its energy efficiency and environmentally friendly properties compared to traditional refrigerants.
