Ammonia, also known as azane, is a colorless, pungent gas composed of
nitrogen and hydrogen. It is the simplest stable compound of these
elements and serves as a starting material for the production of many
commercially important nitrogen compounds. Ammonia is highly soluble
in water to become liquid ammonia. It is one of the most abundant
nitrogen-containing compounds in the atmosphere. It has various uses
as a fertilizer, refrigerant, cleaner, and chemical building block.
Please note that ammonia is a poisonous gas and should be handled with
care.

Ammonia has a wide range of uses across various industries. Here are
some of them:

• Industry: Ammonia is used extensively in several industries. It is
  used either as a stabilizer, neutralizer or as a source of nitrogen
  to carry out several functions. Ammonia is used in wastewater
  treatment, leather, rubber, paper, food and beverage industries. It
  also is used in cold storage, refrigeration systems and in the
  production of pharmaceuticals. Ammonia is used in the printing as
  well as cosmetics industries. It is also used in fermentation.
• Agriculture: Ammonia is used mainly in Agricultural industries.
  About 90 % of all ammonia produced is used in this field. Since
  ammonia acts as a rich source of nitrogen and other elements, it is
  used in fertilizers to basically sustain food production. It is also
  used in the production of liquid fertilizer solutions consisting of
  compounds like ammonium nitrate, salts, urea and others. And there’s
  more. Ammonia is often used as an antifungal agent on certain fruits
  and as preservatives.
• Household Products: Ammonia is one of the main ingredients in a lot
  of household cleaning products. It is used as a cleaning agent and
  can be used to remove stains or clean mirrors, tubs, sinks, windows
  and more. Some other uses include antimicrobial agent or an
  antiseptic, and ammonia is also used as a fuel.
• Manufacturing Various Compounds: We find uses of Ammonia in the
  manufacturing of a number of compounds like nitric acid, Hydrogen
  cyanide, Ammonium carbonate, Phenol, Urea, Amino acids, and a lot of
  other items.
• Metal Treating: Here dissociated ammonia is used in operations like
  carbo nitriding, nitriding, furnace brazing, bright annealing,
  sintering, atomic hydrogen welding and other operations.
• Petroleum and Mining: In the petroleum industry ammonia is utilized
  in counterbalancing the acid constituents of oil which is in crude
  form. Please note that while ammonia is found in many products,
  prolonged or high exposure can be harmful. Always handle products
  containing ammonia with care.
