NH₃ is the chemical formula for ammonia, a compound composed of one nitrogen atom (N) and three hydrogen atoms (H). Ammonia is a colorless gas with a characteristic pungent smell. It is commonly used in fertilizers, cleaning products, and industrial applications. It also plays a crucial role in the nitrogen cycle in nature. In aqueous solution, ammonia can act as a weak base, forming ammonium ions (NH₄⁺) when it reacts with water.
