Ammonium is a modified form of ammonia that has an extra hydrogen atom. It is a positively charged molecular ion with the chemical formula NH + 4 or [NH 4] +.It is formed by the addition of a proton (a hydrogen nucleus) to ammonia (NH 3).
The salts produced by the action of ammonia on acids are known as the ammonium salts and all contain the ammonium ion ([NH 4] +). [38] Although ammonia is well known as a weak base, it can also act as an extremely weak acid. It is a protic substance and is capable of formation of amides (which contain the NH − 2 ion).
When a salt of a metal ion, with the generic formula MX n, is dissolved in water, it will dissociate into a cation and anions. [citation needed]+ + (aq) signifies that the ion is aquated, with cations having a chemical formula [M(H 2 O) p] q+ and anions whose state of aquation is generally unknown.
NH4 or NH 4 or NH-4 may refer to: Ammonium, the cation NH + 4 in chemistry; National Highway 4 (India), new numbering for a National Highway in India; National Highway 4 (India, old numbering), a major National Highway in western and southern India; New Hampshire Route 4, a short state highway located in eastern Strafford County, New Hampshire ...

Because ammonium iodate consists of the reducing ammonium ion and the oxidizing iodate ion, it already starts to decompose at 150 °C into nitrogen, oxygen, iodine and water. NH 4 IO 3 → 1 / 2 N 2 + 1 / 2 O 2 + 1 / 2 I 2 + 2H 2 O
Ammonium dinitramide (ADN) is an inorganic compound with the chemical formula [N H 4][N(NO 2) 2].It is the ammonium salt of dinitraminic acid HN(NO 2) 2.It consists of ammonium cations [NH 4] + and dinitramide anions − N(NO 2) 2.
Ammonium perchlorate ("AP") is an inorganic compound with the formula NH 4 ClO 4.It is a colorless or white solid that is soluble in water. It is a powerful oxidizer.Combined with a fuel, it can be used as a rocket propellant called ammonium perchlorate composite propellant.
