Ammonium formula

Molfile expand.

Ammonia is an inorganic chemical compound of nitrogen and hydrogen with the formula N H 3. 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 precursor to fertilisers. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products.

A cation is an electron-deficient species that carries a positive charge. A polyatomic ion, also known as a molecular ion, is a covalently bonded set of two or more atoms or a metal complex that can be thought of as a single unit and has a net charge that is greater than zero. In ammonia, nitrogen is a central atom with 5 electrons in its valence shell, 3 of which are shared with 3-H atoms, and 1 lone pair of electrons complete the valence shell configuration. It is an electron-rich species nucleophile because it has one lone pair electron unshared electron pair and can donate this electron pair to another atom electrophile. As a result, ammonia is a donor, and when the Ammonia atom donates its lone pair to the proton ammonium ion is formed. Being polar covalent bonds, all four N—H bonds are equivalent. The ion is isoelectronic with methane and borohydride and has a tetrahedral structure. Chemically, the ammonium ion behaves similarly to the ions of alkali metals, particularly the potassium ion, which is nearly the same size. Since it degrades in water to form ammonia and a hydrogen ion, the ammonium ion acts as a weak acid in aqueous solutions. Ammonium ions in a solution can be identified by adding a dilute sodium hydroxide solution and gently heating it. Ammonium ions will be converted to ammonia gas if they are present.

It is formed by the protonation of ammonia NH 3. Thus, the treatment of concentrated solutions of ammonium salts with a strong base gives ammonia. When ammonia is dissolved in water, a tiny amount of it converts to ammonium ions:. The degree to which ammonia forms the ammonium ion depends on the pH of the solution. If the pH is low, the equilibrium shifts to the right: more ammonia molecules are converted into ammonium ions.

Ammonia and ammonium are nitrogen -containing compounds. Both are polyatomic compounds that are composed of more than two atoms per molecule or ion. Ammonium is derived from ammonia. Ammonia can be found as a gas while Ammonium can be found in all three phases of matter. Though they have nearly similar chemical compositions, there are many differences between ammonia and ammonium. The main difference between ammonia and ammonium is that ammonia is a neutral compound whereas ammonium is a cation. Ammonia is an inorganic compound having the chemical formula NH 3. It is a gaseous compound.

Ammonia is common in nature, both terrestrially and in the outer planets of the Solar System. It is widely used in dilute form, but is both caustic and hazardous in its concentrated form.

In the 15th century, Basilius Valentinus showed that ammonia could be obtained by the action of alkalis on sal ammoniac. Principles of Biochemistry 4th ed. Signal word. Archived PDF from the original on 9 October Retrieved 8 November The hydrogen atoms in the ammonium ion can be substituted with an alkyl group or some other organic group to form a substituted ammonium ion IUPAC nomenclature: aminium ion.

ISSN Retrieved 23 April Most studies involving liquid ammonia solutions are done in reducing conditions; although oxidation of liquid ammonia is usually slow, there is still a risk of explosion, particularly if transition metal ions are present as possible catalysts.

Roasting struvite releases ammonia vapours. Likewise, defects in the enzymes responsible for the urea cycle, such as ornithine transcarbamylase , lead to hyperammonemia. Ammonia production currently creates 1. Global production was estimated as being million tonnes in tons of fixed nitrogen. Ammonia is converted to carbamoyl phosphate by the enzyme carbamoyl phosphate synthetase , and then enters the urea cycle to be either incorporated into amino acids or excreted in the urine. In an unusual process, ammonium ions form an amalgam. The interstellar abundance for ammonia has been measured for a variety of environments. Chemical Energy. Interactive image.
