Ammonia is a colorless gas with a sharp, pungent odor, well known for its role in agriculture and industry. It is highly soluble in water, forming ammonium hydroxide, a weak alkaline solution. Ammonia is one of the most essential chemicals for fertilizer production, serving as the basis for urea and ammonium nitrate, which supply nitrogen to crops worldwide. Its industrial significance extends to refrigeration systems, where it is used as an efficient and eco-friendly refrigerant, as well as in the production of plastics, explosives, and dyes. Ammonia also finds use in household cleaning agents due to its degreasing and stain-removing abilities. Despite its usefulness, ammonia is hazardous: it is toxic when inhaled, corrosive to skin and eyes, and can be dangerous at high concentrations. In agriculture, it is sometimes applied directly as anhydrous ammonia fertilizer. Safe handling requires pressurized containers and protective equipment. As one of the most widely produced industrial chemicals, ammonia plays a central role in global food production, refrigeration, and manufacturing industries, making it indispensable for modern life.
