Depending on the number of organic groups, the ammonium cation is called a primary, secondary, tertiary, or quaternary. [4], Ammonium is an important source of nitrogen for many plant species, especially those growing on hypoxic soils. Primary, secondary, and tertiary ammonium salts serve the same function, but are less lipophilic. In mammals, sharks, and amphibians, it is converted in the urea cycle to urea, because urea is less toxic and can be stored more efficiently. Short- and linear-chain APPs ( n < 100) are more water sensitive (hydrolysis) and less thermally stable than longer-chain APPs ( n > 1000), which show very low water solubility (<0.1 g/100 ml). It is an ammonia molecule, NH 3, protonated (with a hydrogen ion added) to make NH 4 +. Lv 4. ammonium ion= NH4^(+) carbonate ion- CO3^(2-) so ammonium carbonate= (NH4)2 CO3.

Thereafter, all four N–H bonds are equivalent, being polar covalent bonds. [6][7][8] Ammonium is expected to behave as a metal (NH+4 ions in a sea of electrons) at very high pressures, such as inside gas giant planets such as Uranus and Neptune. The IUPAC name of ammonium ion is azanium. These cations, such as the tetra-n-butylammonium cation, are sometimes used to replace sodium or potassium ions to increase the solubility of the associated anion in organic solvents. In terms of size, the ammonium cation (rionic = 175 pm) resembles the caesium cation (rionic = 183 pm).

The number of formula units of ammonium carbonate is 8.903/114.10 or 0.078028. If the pH is high (the concentration of hydrogen ions is low), the equilibrium shifts to the left: the hydroxide ion abstracts a proton from the ammonium ion, generating ammonia. [5], The ammonium ion has very similar properties to the heavier alkali metals cations and is often considered a close equivalent. The ammonium ion is generated when ammonia, a weak base, reacts with Brønsted acids (proton donors): The ammonium ion is mildly acidic, reacting with Brønsted bases to return to the uncharged ammonia molecule: Thus, treatment of concentrated solutions of ammonium salts with strong base gives ammonia. In fish and aquatic invertebrates, it is excreted directly into the water.
