What is Ammonium Nitrate?

Ammonium nitrate is one ionic salt consisted of of the ammonium cation (NH4)+ and the nitrate anion (NO3)–. The chemical formula of this link is NH4NO3.

You are watching: Is nh4no3 acidic basic or neutral

Ammonium nitrate conveniently dissolves in water by dissociating into its ingredient ions. This salt is acidic in nature due to the fact that it is derived from a weak basic (NH3) and also a strong acid (HNO3).

NH4NO3 deserve to be prepared from the acid-base reaction between nitric acid and also ammonia, described by the complying with chemical equation:

NH3 + HNO3 → NH4NO3

This reaction is highly exothermic and proceeds violently. Ammonium nitrate is likewise known for its oxidizing powers. The is widely provided in plenty of explosives offered in the mining and also construction sectors. NH4NO3 is also one that the vital components that ANFO, among the most popular choices of commercial explosives.

Structure of Ammonium Nitrate

This compound attributes an ionic bond between an ammonium ion and a nitrate ion. The framework of one NH4NO3 molecule is shown below.

*

The pi electron in the nitrate ion space delocalized as result of resonance. The net charge on this ion is -1 (since the nitrogen atom stop a charge of +1 and each oxygen atom hold a charge of -⅔). Therefore, just one NH4+ ion can type an ionic bond v one NO3– ion.

Ammonium Nitrate Properties

Molar Mass/ molecule Weight80.043 grams every mole
Density1.725 grams every cubic centimetre
Melting Point442.8K (169.6oC)
Boiling PointDecomposes at 483K (210oC)

Physical Properties

It has actually a trigonal decision structure.It is fairly soluble in water; that is solubility at 20oC is 150g/100ml. The solubility rises to 1024g/100ml once the temperature is raised to 100oThe resolution of NH4NO3 in H2O is very endothermic.This compound has very low shock and friction sensitivities.

Chemical Properties

When NH4NO3 is reacted v the hydroxides the alkali metals, the nitrates the alkali metals are formed along with ammonia.When exploded, this compound yields N2, O2, and water as the through products.Despite gift a ingredient of plenty of explosives, ammonium nitrate is not an explosive through itself. It have to be mixed with a primary explosive such as an azide to form an explosive mixture.

Uses the Ammonium Nitrate 

Some crucial applications that this ionic salt are detailed below.

NH4NO3 is a vital component of many fertilizers because it is fairly rich in nitrogen (34%).Another advantage of this compound is that it doesn’t lose its nitrogen to the atmosphere, together is the case with urea.When combined with fuel oil, it creates an explosive recognized as ANFO, which is one of the most famous industrial explosives.The resolution of this compound in water is rather endothermic, making that an ideal an option of product in instant cold packs.It is also used in the mining and also construction market as a component of explosives.

Despite its numerous applications, the use of this link is being progressively phased the end by the governments of many countries as result of its scope because that misuse. Ammonium nitrate was one of the key ingredients the the explosives the were supplied in the 2011 Delhi bombings and also the 2013 blasts in Hyderabad.


Used to make fertilizers and also explosives, and also as a nutrient in antibiotic and yeast growth. Ammonium nitrate is the nitric mountain ammonium salt. It has a role as a fertilizer, an oxidizing agent and an explosive.


Ammonium nitrate is not acid yet a salt yet the equipment is acidic because it is a salt v a weak base (ammonium hydroxide) and also a heavy nitric acid.


It feeling cold as soon as ammonium nitrate is liquified in water which suggests an endothermic reaction. In an endothermic reaction, the ammonium nitrate dissolves in water, a chemistry reaction the absorbs warmth rather than releases it. Ammonium nitrate consists of tightly packed, ionic bonds.


Ammonium nitrate is a chemical compound used as a fertilizer in agriculture, for creating pyrotechnics, together an ingredient in cold packs, and for clinical demonstrations. This is likewise used in mining and also quarrying to produce regulated explosions.

Ammonium nitrate fertilizer is the compound’s most common application but it additionally has a an extremely volatile quality, make it beneficial in part industries. The use of ammonium nitrate in gardens and also large-scale farming fields stimulates plant growth and provides a ready source of nitrogen the plants can draw from.
