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). Depending on the number of organic groups, the ammonium cation is called a primary , secondary , tertiary , or quaternary .
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.
Ammonium heptamolybdate is the inorganic compound whose chemical formula is (NH 4) 6 Mo 7 O 24, normally encountered as the tetrahydrate.A dihydrate is also known. It is a colorless solid, often referred to as ammonium paramolybdate or simply as ammonium molybdate, although "ammonium molybdate" can also refer to ammonium orthomolybdate, (NH 4) 2 MoO 4, and several other compounds.
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 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).
Ammonium iodide is the inorganic compound with the formula NH 4 I. A white solid. It is an ionic compound, although impure samples appear yellow.This salt consists of ammonium cation and an iodide anion. [1]
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).
The singly charged ion can be any of the full range of potassium, rubidium, cesium, ammonium (), or thallium. [1] As a mineral the ammonium nickel salt, (NH 4) 2 Ni(SO 4) 2 · 6 H 2 O, can be called nickelboussingaultite. [2] With sodium, the double sulfate is nickelblödite Na 2 Ni(SO 4) 2 · 4 H 2 O from the blödite family. Nickel can be ...
