Formula Chemical The chemical formula for ammonium nitrate is

It contains one ammonium ion and one nitrate ion 

Physical properties

Appearance: It is usually a white crystalline solid.

Solubility: Highly soluble in water around 1900 g/L at 20°C.

Melting Point: Melts at approximately 170°C (338°F).

Density: Approximately 1.73 g/cm³.

Odor: Generally odorless.

Hygroscopicity: Ammonium nitrate is hygroscopic; meaning it can absorb moisture from the air.

Deliquescence: It dissolves when it absorbs adequate amount of moisture within it.

Chemical properties

Decomposition: On heating, ammonium nitrate decomposes into nitrogen dioxide, water vapor, and oxygen. The reaction is exothermic and at high temperatures might result in explosive decomposition.

Acid-Base Reactions: Ammonium nitrate is a weak acid. In solution, it may dissociate into ammonium ions and nitrate ions.

Reaction with Bases: It reacts with strong bases, forming ammonia gas

Oxidizing Agent: Ammonium nitrate is also an oxidizing agent and thus can continue burning. Such a compound catches fire with combustible material, which is extremely dangerous under certain conditions.

Formation of Complexes: It can form complexes with most metal ions in solution, but it affects solubility and reactivity.

Application

Fertilizer: A widely used nutrient in agriculture that offers a quick nitrogen source, it will spur more plant growth and crop yields. It is very much enjoyed for its ease to solubility and its effectiveness.

Explosives: This is a very crucial component in numerous configurations of explosives, such as ANFO (ammonium nitrate fuel oil), used in mining, construction, and demolition because of decomposition and the mass amount of energy it unleashes.

Food Preservation: It is used at times in food processing as a curing agent for meats to preserve color and flavor.

Cold Packs: It can be used in instant cold packs, where its dissolution in water absorbs heat to give a cooling effect.

Chemical Reagent: Since it is a source of nitrogen, it is used in different chemical reactions, especially in research and in analytical chemistry.

Soil amendment: The soil fertility and structural properties would improve if the addition is done to the soil, thus increasing water retention capacity.

Conclusion

Ammonium nitrate​ is a compound with wide scope of application, mainly as fertilizer and a component of an explosive. Because this compound is highly soluble in water, its use as a provider of nutrients to plants greatly improves agricultural productivity. Its use in releasing energy—which is important in mining and construction—is also pointed out, considering the roles of this compound in explosive formulations.

The ammonium nitrate however has more advantages but it poses more risks concerning safety owing to its property of explosive decomposition under specific conditions. This therefore calls for cautious handling as well as storage to minimize danger.

Generally, Ammonium Nitrate is an essential chemical that can be very vital in agriculture and industries while at the same time balances utility with the need for responsible management.
