Ammonia

Ammonia \Am*mo"ni*a\, n. [From sal ammoniac, which was first obtaining near the temple of Jupiter Ammon, by burning camel's dung. See Ammoniac.] (Chem.) A gaseous compound of hydrogen and nitrogen, NH3, with a pungent smell and taste: -- often called volatile alkali, and spirits of hartshorn.

Douglas Harper's Etymology Dictionary
ammonia

1799, Modern Latin, coined 1782 by Swedish chemist Torbern Bergman (1735-1784) for gas obtained from sal ammoniac, salt deposits containing ammonium chloride found near temple of Jupiter Ammon (from Egyptian God Amun) in Libya, from Greek ammoniakos "belonging to Ammon." The shrine was ancient already in Augustus' day, and the salts were prepared "from the sands where the camels waited while their masters prayed for good omens" [Shipley].\n

\nThere also was a gum form of sal ammoniac, from a wild plant that grew near the shrine, and across North Africa and Asia. A less likely theory traces the name to Greek Armeniakon "Armenian," because the substance also was found in Armenia. Also known as spirit of hartshorn and volatile or animal alkali.

Ammonia

Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH. It is a colourless gas with a characteristic pungent smell. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceuticals and is used in many commercial cleaning products.

Although common in nature and in wide use, ammonia is both caustic and hazardous in its concentrated form. It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.

The global industrial production of ammonia in 2014 was , a 16% increase over the 2006 global industrial production of .

NH boils at at a pressure of one atmosphere, so the liquid must be stored under pressure or at low temperature. Household ammonia or ammonium hydroxide is a solution of NH in water. The concentration of such solutions is measured in units of the Baumé scale ( density), with 26 degrees baumé (about 30% (by weight) ammonia at ) being the typical high-concentration commercial product.

Ammonia (band)

An alternative rock band from Australia, Ammonia made a name for themselves in the 1990s, producing a mixture of grunge and guitar pop (a sound they described as 'pop-metal'). The group began in 1992, initially comprising guitarist Dave Johnstone (ex Hideous Goldsteins), drummer Alan Balmont (ex Dear Octopus, Cherrytones) and bass player Phil Natt. This line up performed under the name Fuzzswirl, and following departure of Natt, continued to perform with a variety of bass players around their hometown of Perth. It wasn't until 1993 when bassist Simon Hensworth joined the group that the name was changed to Ammonia. The band was considering the name "Glorious Noise Earthquake", but selected Ammonia for its simplicity after Hensworth stumbled across the word in a science textbook.

Usage examples of "ammonia".

Besides the glands, both surfaces of the leaves and the pedicels of the tentacles bear numerous minute papillae, which absorb carbonate of ammonia, an infusion of raw meat, metallic salts, and probably many other substances, but the absorption of matter by these papillae never induces inflection.

As such minute doses of the salts of ammonia affect the leaves, we may feel almost sure that Drosera absorbs and profits by the amount, though small, which is present in rainwater, in the same manner as other plants absorb these same salts by their roots.

Manner of performing the experiments--Action of distilled water in comparison with the solutions--Carbonate of ammonia, absorbed by the roots--The vapour absorbed by the glands--Drops on the disc--Minute drops applied to separate glands--Leaves immersed in weak solutions--Minuteness of the doses which induce aggregation of the protoplasm--Nitrate of ammonia, analogous experiments with--Phosphate of ammonia, analogous experiments with--Other salts of ammonia--Summary and concluding remarks on the action of salts of ammonia.

We may infer that the carbonate of ammonia is absorbed by the glands, not only from its action being so rapid, but from its effect being somewhat different from that of other salts.

As, however, the aggregation caused by this salt travels down the tentacles at a quicker rate than when insoluble particles are placed on the glands, it is probable that ammonia in some form is absorbed not only by the glands, but passes down the tentacles.

Filter off the precipitate and wash with hot water containing a little sodium acetate, dissolve it off the filter with hot dilute hydrochloric acid, add ammonia in excess, and pass sulphuretted hydrogen for five minutes.

If the lead is present as sulphate in sodic acetate solution, it is well to render it distinctly alkaline with ammonia.

Boil off the gas, add ammonia until a precipitate is formed, and then acidify somewhat strongly with acetic acid.

To separate these, ammonia is added till the solution is alkaline, and then acetic acid in slight excess.

After precipitating as ammonic-magnesic phosphate with sodium phosphate, and well washing with ammonia, it is dissolved in dilute hydrochloric acid, neutralised with ammonia, and sodic acetate and acetic acid are added in the usual quantity.

On dissolving in hydrochloric acid, neutralising with ammonia, adding 5 c.

Glutamic acid, without which ammonia accumulates in the brain and kills, dribbled along the floor while they glared, and D-ribose, and D-2-deoxyribose, adenine, guanine, uracil, cytosine, thymine and 5-methyl cytosine without which no thing higher than a trilobite can pass on its shape and meaning to its next generation.

If there be great prostration, with cold extremities, the carbonate of ammonia should be administered, in doses of from one to two grains, every second hour, in gum arabic mucilage.

A similar result followed from an immersion of only 15 minutes in a solution of one part of carbonate of ammonia to 218 of water, and the adjoining cells of the tentacles, on which the papillae were seated, now likewise contained aggregated masses of protoplasm.
