Ammonia Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH3. The simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. It contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers.

- What is Ammonia? Ammonia is a nutrient that contains nitrogen and hydrogen. Its chemical formula is NH 3 in the un-ionized state and NH 4 + in the ionized form. Total ammonia is the sum of both NH 3 and NH 4 + . Total ammonia is what is measured analytically in water. Why is it Important? Ammonia is the preferred nitrogen-containing nutrient for plant growth. Ammonia can be converted to nitrite (NO 2 ) and nitrate (NO 3) by bacteria, and then used by plants. Nitrate and ammonia are the most common forms of nitrogen in aquatic systems.

Formation and detoxification of ammonia, urea cycle and its regulation, hyperammonaemia Ammonia-NH3 synthesis. Ammonia-NH3 is a toxic weak basic compound that needs to be detoxified and eliminated from the body. Ammonia derives from the metabolism of amino acids and especially that of gluconeogenesic transversion of amino acid into glucose. Glucose can be synthesized from amino acid carbon skeleton after the removal of its amino group.

Ammonia Ammonia is a colourless gas with a characteristic pungent smell. It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules; the liquid boils at −33.3 °C (−27.94 °F), and freezes at −77.7 °C (−107.86 °F) to white crystals.mmonia is miscible with water. In an aqueous solution, it can be expelled by boiling. The aqueous solution of ammonia is basic. The maximum concentration of ammonia in water (a saturated solution) has a density of 0.880 g/cm 3 and is often known as '.880 ammonia'.

It can be denoted by the symbols NH3(aq). It is sometimes thought of as a solution of ammonium hydroxide. Although the name ammonium hydroxide suggests an alkali with composition [NH4+], it is actually impossible to isolate samples of NH4OH. The ions NH4+ and OH− do not account for a significant fraction of the total amount of ammonia except in extremely dilute solutions.

The Facts About Ammonia Ammonia is one of the most widely produced chemicals in the United States. In pure form, it is known as anhydrous ammonia. Ammonia is also produced in the human body and is commonly found in nature. It is essential in the body as a building block for making proteins and other complex molecules. In nature, ammonia occurs in soil from bacterial processes. It is also produced when plants, animals and animal wastes decay.

- Ammonia may be a reasonable thalassogen, so it should be available in sufficient quantities for use as a life-fluid on other worlds. Chemically, liquid ammonia is an unusually close analogue of water. There is a whole system of organic and inorganic chemistry that takes place in ammono, instead of aqueous, solution.t only 60 atm, far less than Jupiter or Venus in our solar system, ammonia boils at 98 °C instead of -33 °C. (Ammonia life is not necessarily low temperature life.) So at 60 atm the liquidity range has climbed to 175 °C, which should be ample for life.
