About Ammonia

• It is a colorless, pungent gas composed of nitrogen and hydrogen with the formula NH3.
• It is the simplest stable compound of these elements and serves as a starting material for the production of many commercially important nitrogen compounds.
• It exists naturally in humans and in the environment. 
  • In the environment, ammonia is part of the nitrogen cycle and is produced in soil from bacterial processes. 
  • Ammonia is also produced naturally from decomposition of organic matter, including plants and animals.
• Industrial production: Manufactured mainly by the Haber–Bosch process (from nitrogen and hydrogen).
• Ammonia gas can be dissolved in water. This kind of ammonia is called liquid ammonia or aqueous ammonia. Once exposed to open air, liquid ammonia quickly turns into a gas.
• Uses:
  • The major use of ammonia is as a fertilizer. 
    • Ammonia is a basic building block for ammonium nitrate fertilizer, which releases nitrogen, an essential nutrient for growing plants.
    • About 90 percent of ammonia produced worldwide is used in fertilizer.
  • Additional uses include as a refrigerant, stabilizer, neutralizer, and purifier — particularly in food transport and water treatment applications. 
  • It can also be used in the manufacture of plastics, explosives, fabrics, dyes, and pharmaceuticals.
• Exposure to high levels of ammonia in air may be irritating to a person’s skin, eyes, throat, and lungs and cause coughing and burns.
• To prevent the release of toxic fumes, ammonia should not be mixed with other chemicals (especially chlorine bleach).
