This process requires ammonia which is produced by the Haber process of combining hydrogen and nitrogen. They are then prepared and sold off as commercial AND products. To prevent caking these prills or granules are coated. These granules or beads are then dried further and cooled. The AN melt is also converted to granules by spraying as well as tumbling inside a rotating drum. This AN is then converted into small beads in a spray tower. This highly concentrated Ammonium nitrate is called Ammonium nitrate melt or AN melt. The solution is then evaporated to remove excess water and obtain an Ammonium nitrate content of 95-99% (depending upon the grade of the product). The resultant solution contains as much as 83% of Ammonium nitrate. This means that it produces a large amount of heat energy during the process. This gaseous ammonia is then added to concentrated nitric acid to form Ammonium nitrate. The reaction is summarized as:įor this process, ammonia is used in its gas form or anhydrous form. A molecule of Nitric acid (acidic) joins together with a molecule of ammonia (basic) to form a single molecule of ammonium nitrate. Industrial production of Ammonium nitrate is based on an acid-base reaction between ammonia and nitric acid. Most of the Ammonium nitrate that is produced is synthesized chemically. How is Ammonium Nitrate Produced Industrially? However, now most, if not all, of the ammonium nitrate is produced chemically. It is often found in conjunction with other compounds namely nitrates, iodates and other halide minerals.Įarlier, Ammonium nitrate used to be mined as a mineral from these regions. In these regions, it is found as a crust on the ground. Only the driest regions of the desert are suitable for finding ammonium nitrate. It is commonly found in the Atacama Desert in Chile. It is found as a gigabyte which is called the Ammonium analogue of saltpetre. In nature, ammonium nitrate is found as a natural mineral. Where Does Ammonium Nitrate Occur Naturally? The molecular weight of ammonium nitrate= 2 * weight of nitrogen atom + 4 * weight of hydrogen atom + 3 * weight of an oxygen atom The molecular weight of hydrogen= 1.00784 The molar mass of ammonium nitrate= the sum of the molar mass of all its constituents in the correct proportion. Let us look at how to calculate the molecular weight of the given compound: How to Calculate the Molecular Weight of the Ammonium Nitrate? The molar mass of Ammonium nitrate is 80.043 gm per mole. What is the Molar Mass of Ammonium Nitrate? It tends to absorb moisture from the air, making it hygroscopic. Ammonium nitrate acts stable under normal conditions during its usage and storage but emits nitrous oxide, commonly known as the laughing gas when heated to decomposition. The density of the substance is noted as 1.725 gm per cm³, which makes it easily soluble in different substances. Ammonium nitrate is either white or grey coloured in its pure form. What are the Physical Properties of Ammonium Nitrate?Īmmonium nitrate is a solid colourless crystalline substance. However, due to concern over its misuse, many countries are debating about stopping using ammonium nitrate. It is largely used in the agricultural industry as a fertilizer. It is a white solid crystal that is readily soluble in water. When these two unite they form Ammonium nitrate with a formula NH 4 NO 3. Ammonium has a chemical formula NH 4+ and nitrate has the chemical formula NO 3. The molecule of ammonium nitrate is formed by the union of 2 nitrogen atoms, 4 hydrogen atoms and 3 oxygen atoms. Ammonium nitrate has distinct chemical and physical properties which are used for many purposes.Īmmonium nitrate is a chemical compound that is made up when an ammonium ion unites with a nitrate ion. Ammonium nitrate is a chemical compound that has many uses and is made up of atoms of nitrogen, hydrogen, oxygen.
