Ammonia is known to behave as a weak base since it combines with many acids to form salts. For example, when it is reacted with hydrochloric acid, ammonia is converted into ammonium chloride. All the salts that are produced from such acid-base reactions are known to contain the ammonium cation, denoted by nh4+.

Ammonia gas dissolves easily in water to form ammonium hydroxide, a caustic body or metabolized to compounds found endogenously at appreciable levels.
Chapter i introduction the ammonium ion, nh4+, is an important member of the group of nitrogen-containing compounds that act as nutrients for aquatic plants and algae. In surface water, most of the ammonia, nh3, is found in the form of the ammonium ion, nh4+.

Quaternary ammonium compounds (commonly known as quats or qacs) are cationic surfactants (surface active agents) that combine bactericidal and virucidal (generally only enveloped viruses) activity with good detergency and, therefore, cleaning ability. Although other surfactant types, such as anionic, nonionic and, amphoteric surfactants (referring to their overall charge) have some antimicrobial activity depending on the specific biocide, the cationic surfactants (and some of the amphoterics.
Knowledge of hydroxylamine oxidoreductase, which oxidizes hydroxylamine formed by ammonia monooxygenase to nitrite, is informed by a crystal structure and detailed spectroscopic and catalytic studies. Other inorganic nitrogen compounds, including no, n2o, no2, and n2 can be consumed and/or produced by ammonia-oxidizing bacteria.
Ammonia and ammonium salts are used in cleansing agents and as food additives (1,4), and ammonium chloride is used as a diuretic [source: hazardous substances data bank: ammonium chloride.
Water test reports generally are based upon ammonium nitrogen. Ammonia and its ionized form, ammonium, are naturally occurring organic compounds.
Ammonium is an onium cation obtained by protonation of ammonia. It has a role as a human metabolite, a saccharomyces cerevisiae metabolite, an escherichia coli metabolite and a cofactor. It is a nitrogen hydride, an onium cation and a monovalent inorganic cation.

Ammonia is unlikely to kill germs, and can't disinfect against viruses. However, ammonia is used to create quarternary ammonium compounds (qacs), which is an effective disinfectant against viruses. You should be careful when using ammonia or qacs in your home, as they can be potentially harmful if not used correctly.
The disinfectants in their literature review include two alcohols (ethanol and propanol), sodium hypochlorite, peroxides, aldehydes (formaldehyde and glutardialdehyde), two different types of quaternary ammonium compounds (bac, 1 and didecyldimethylammonium chloride, 2; figure 2), and several others. It is from this data table that the cdc provided its recommendations on abhs and regarded bac, a common quaternary ammonium compound (qac), as ineffective at killing the virus.
Ammonia (nh 3) and ammonium compounds are among the most common sources of nuisance odor complaints around the world. The largest source of global ammonia emissions is in agriculture, either from large-scale concentrated animal feeding operations or in the production of fertilizers.
The following table summarizes the difference between quaternary ammonium and ammonia. Quaternary ammonium is a cation derived from an ammonia molecule. The key difference between quaternary ammonium and ammonia is that quaternary ammonia molecule has a central nitrogen atom bound with four alkyl groups whereas ammonia molecule contains one nitrogen centre bound to three hydrogen atoms.
Ammonia was used in egypt to heat the temple of amon, and the gas from camel manure left ammonium chloride on the top and walls of the temple. Ammonia actually got its name from the substance ammonium chloride, known as the salt of amon. Ammonia gas was first produced in 1774 by joseph priestley, an english chemist.
