Ammonia is a colorless gas with a distinct, pungent odor. Its chemical formula is NH3, indicating that it consists of one nitrogen atom and three hydrogen atoms. Ammonia is commonly found in nature, produced by the decomposition of organic matter and is also a key component in the nitrogen cycle, which is essential for plant growth. In industry, ammonia is primarily used as a fertilizer, helping to provide essential nutrients to crops. It is also utilized in the production of various chemicals, cleaning products, and refrigeration systems. Due to its high solubility in water, ammonia can easily be converted into ammonium hydroxide, which is often used in household cleaners.
