The NH3 is the chemical formula for a compound of Nitrogen and Hydrogen called ‘‘Ammonia’’. Ammonia is a colorless gas with a characteristic pungent smell. It has a molar mass of 17.031 g/mol. The Haber process is the major way through which Ammonia is produced. Ammonia evaporates quickly at room temperature. It is interesting to know that it is slightly lighter than air and is not ordinarily flammable but in extremely high concentrations can create an explosive mixture with air.
It is a universal nitrogenous waste, particularly among aquatic organisms and it contributes positively to the nutritional needs of terrestrial plants by serving as a precursor to food and fertilizers. Ammonia dissolves easily in water to form ammonium hydroxide solution which can cause irritation and burns. Ammonia gas is easily compressed and forms a clear, colorless liquid under pressure. Ammonia, NH3, is one of the most commonly produced industrial chemicals in the United States.
