    Ammonia | Wikipedia

    • Ammonia is an inorganic chemical compound of nitrogen and hydrogen with the formula NH3. A stable binary hydride and the simplest pnictogen hydride, ammonia is a colourless gas with a distinctive pungent smell. Biologically, it is a common nitrogenous waste, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a pre… See more

    Properties

    Ammonia is a colourless gas with a characteristically 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. Gaseous a… See more

    Detection and determination

    Ammonia and ammonium salts can be readily detected, in very minute traces, by the addition of Nessler's solution, which gives a distinct yellow colouration in the presence of the slightest trace of ammonia or ammoniu… See more

    History

    The ancient Greek historian Herodotus mentioned that there were outcrops of salt in an area of Libya that was inhabited by a people called the 'Ammonians' (now the Siwa oasis in northwestern Egypt, where salt lakes st… See more

    Applications

    In the US as of 2019 , approximately 88% of ammonia was used as fertilisers either as its salts, solutions or anhydrously. When applied to soil, it helps provide increased yields of crops such as maize and wheat. 30% of agricultur… See more

    Toxicity

    The toxicity of ammonia solutions does not usually cause problems for humans and other mammals, as a specific mechanism exists to prevent its build-up in the bloodstream. Ammonia is converted to carbamoyl … See more

  1. Ammonia
    NH3 refers to ammonia, which is a colourless, pungent gas composed of nitrogen and hydrogen12. It is the simplest stable compound of these elements and serves as a starting material for the production of many commercially important nitrogen compounds1. In water, ammonia exists in two forms: the ionized form (ammonium, NH4+) and the unionized form (ammonia, NH3)3. NH3-N represents the nitrogen content of ammonia, while NH4-N represents the nitrogen content of the ammonium ion4.

    www.britannica.com/summary/ammonia
    Ammonia (NH 3) is a common toxicant derived from wastes (see Figure 1), fertilizers and natural processes. Ammonia nitrogen includes both the ionized form (ammonium, NH 4+) and the unionized form (ammonia, NH 3). An increase in pH favors formation of the more toxic unionized form (NH 3), while a decrease favors the ionized (NH 4+) form.

    NH3-N represents the Nitrogen content of the ammonia, NH4-N is the nitrogen content of the ammonium ion. This is used when people wish to track nitrogen through the treatment process. The nitrogen is converted to nitrate NO3- (a negatively charged ion) by the normal treatment processes.
