An example of a reaction forming an ammonium ion is that between dimethylamine, (CH 3) 2 NH, and an acid to give the dimethylammonium cation, [(CH 3) 2 NH 2] +: Quaternary ammonium cations have four organic groups attached to the nitrogen atom, they lack a hydrogen atom bonded to the nitrogen atom.
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.
The phosphomolybdate ion, [PMo 12 O 40] 3−. Ammonium phosphomolybdate is the inorganic salt of phosphomolybdic acid with the chemical formula (NH 4 ) 3 PMo 12 O 40 . The salt contains the phosphomolybdate anion, a well known heteropolymetalate of the Keggin structural class.
The ammonium ion can be displaced with some concentrated nitrates e.g. potassium nitrate,, silver nitrate, etc.: [2] NH 4 ReO 4 + KNO 3 → KReO 4 ↓ + NH 4 NO 3. It can be reduced to nonahydridorhenate with sodium in ethanol: [2] NH 4 ReO 4 + 18Na + 13C 2 H 5 OH → Na 2 [ReH 9] + 13NaC 2 H 5 O + 3NaOH + NH 3 •H 2 O.
Ammonium oxalate is a chemical compound with the chemical formula [N H 4] 2 C 2 O 4.Its formula is often written as (NH 4) 2 C 2 O 4 or (COONH 4) 2.It is an ammonium salt of oxalic acid.It consists of ammonium cations ([NH 4] +) and oxalate anions (C 2 O 2− 4).
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.
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 ...
In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: . NH 3 + H 2 O ⇌ NH + 4 + OH −.. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +
