NH 3 + HNO 3 → NH 4 NO 3. Ammonium nitrate is a colourless crystalline substance (melting point 169.6 °C [337.3 °F]). Because of ammonium nitrate's explosive potential, countries and unions impose strict regulations on how to store and process it. "This is clearly a very significant explosion, and the reported number of deaths is likely to be far higher than currently identified," said David Caldicott, a senior clinical lecturer in medicine at the Australian National University. Kauffman said, in principle, ammonium nitrate should be highly explosive by itself, but it is not. Ammonium nitrate is the most commonly used chemical in the manufacture of commercial explosives. Cerium Ammonium Nitrate, CAN. Ammonium nitrate is classified as dangerous goods and all aspects of its use are tightly regulated. In its pure form, ammonium nitrate isn’t usually explosive – in fact, it’s safe to handle. Under normal conditions, the chemical is highly stable. AN such as ammonium nitrate–fuel oil (ANFO), amatol, etc., are well-known explo- sives. In the Beirut incident, experts suggest fireworks were involved. "The energy given out is what you get as explosive power.". Though the causative agent of the larger, second explosion appears to be ammonium nitrate, the full scale of the devastation in Lebanon isn't yet completely understood and an investigation will be performed. Ammonium nitrate is also known for its oxidizing powers. The reaction starts at fairly mild temperatures but both the rate and the mixture of products depends on the temperature. Approximately 60 percent of the ammonium nitrate produced in the U. S. is sold as a solid product. When heated to above 170 degrees Fahrenheit, ammonium nitrate begins to undergo decomposition. Beirut explosion: How ammonium nitrate caused deadly blast in Lebanon. Ammonium nitrate is a chemical compound which is made up when an ammonium ion unites with a nitrate ion. It is prepared commercially by reaction of nitric acid and ammonia. I would suspect a copper alloy is even more problematic due to the possible mixed metal electrochemical based REDOX reaction alluded to above. This reaction takes place at a temperature of over 300°C. All ammonium nitrate plants produce an aqueous ammonium nitrate solution through the reaction of ammonia and nitric acid in a neutralizer according to the following equation: N H 3 + H N O 3 → N H 4 NO 3. So what is ammonium nitrate, why is it explosive and why do we use it? Heating also poses a danger: ammonium nitrate decomposes at around 230˚C, and can explode when heated to between 260–300˚C if it’s confined. This means that it produces a large amount of heat energy during the process. Ba(NO3)2(aq) + (NH4)2SO4(aq) = BaSO4(s) + 2NH4NO3(aq) Ammonium nitrate, the other product, remains in the solution. The force of the ammonium nitrate explosion is provided by the rapid generation of gas as it breaks down. The primary reaction when it breaks down produces nitrogen, water vapour and oxygen. For example, potassium compounds like nitrogen-potassium and nitrogen-phosphorus-potassium fertilizers have been used to … A ship in the harbor of Texas City, Texas, carrying approximately 2,300 tons of ammonium nitrate caught fire, supposedly via a discarded cigarette, causing a series of explosions that killed 581 people. As a fertilizer, the compound is applied as granules, and fused with ammonium sulfate to minimize the volatile nature of the compound. Imagine a reaction in which solid ammonium nitrate (a component in some fertilizers and an explosive) is dissolved in water to produce an aqueous ammonium nitrate solution. Moisture in the air is quickly condensed, forming a white sphere around the explosion zone. Nitrogen dioxide (NO₂) is a red, bad-smelling gas. Images from Beirut reveal a … According to a report by Al Jazeera, Lebanon Prime Minister Hassan Diab said the explosion was fueled by a stockpile of over 2,700 tons of ammonium nitrate, confiscated and stored for approximately six years at the port. All ammonium nitrate plants produce an aqueous ammonium nitrate solution through the reaction of ammonia and nitric acid in a neutralizer. Microsoft may earn an Affiliate Commission if you purchase something through recommended links in this article. To produce a solid product, the ammonium nitrate solution is concentrated in an evaporator or concentrator. Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat. Because of the differences in … 2(NH4)NO3 + CuSO4 → Cu(NO3)2 + (NH4)2SO4 You need to know the charge of the polyatomic ions of these molecules. “Ammonium nitrate is hygroscopic and forms a hard crust when it absorbs water. Ammonium Nitrate (NH4NO3) is an odorless, crystalline substance that is the result of a reaction between ammonia (NH3) and Nitric Acid (HNO3). After the fireball erupts in the video above, you can immediately see the shock wave expanding away from the blast. In … AMMONIUM NITRATE SAFETY FACT SHEET Many misconceptions exist surrounding the dangers of ammonium nitrate, particularly following the explosion in Beirut, Lebanon in August 2020. In a very useful double replacement reaction, ammonium nitrate can be reacted with sodium hydroxide or sodium carbonate in somewhat differing procedures to yield sodium nitrate, another useful oxidizer, and ammonia gas (with in the latter case carbon dioxide), which can be channeled into cold water to produce a solution. Ammonium nitrate is made by reaction of ammonia with nitric acid in water followed by careful evaporation of the water. Ammonium nitrate decomposes in an exothermic reaction (ΔH = –36 kJ mol −1) to produce three moles of gaseous products for each mole of … The accidental detonation of ammonium nitrate has resulted in a number of accidents in the last century. Time (s) (NH 4 NO 21 (mol/L) 0 1.0 0 1000 0.11 2 2000 0.06 1 3000 0-04 1 4000 0.03 1 A) Obtain The Order Of The Reaction And Calculate The Rate Constant. This reaction is highly exothermic and proceeds violently. Two explosions are said to have rocked the port. This is … See the site’s content usage guidelines. Stop using ammonium lactate topical and call your doctor at once if you have: severe redness or stinging where the medicine was applied. The chemical reaction produces a concentrated form of ammonium nitrate, which produces prodigious amounts of heat. However, if it is contaminated with impurities, the risk of it detonating increases. ammonium nitrate involved in a fire may detonate, especially if confined. Mixed with fuel oil it’s known as ANFO (ammonium nitrate/fuel oil), which accounts for approximately 80% of the 2.7 billion kilograms of explosives used in North America every year. Decomposition creates toxic gases containing ammonia and nitrogen oxides. The force of the ammonium nitrate explosion is provided by the rapid generation of gas as it breaks down. Ammonium nitrate is a common industrial chemical used mainly for fertiliser because it is a good source of nitrogen for plants. Image : Al Arabiya. Chemical reaction. This is due to other reactions generating nitrogen dioxide. In 2015, explosions partly caused by the detonation of around 800 tons of ammonium nitrate rocked the Beijing port of Tianjin, killing 173 people. Images from Beirut reveal a … But ammonium nitrate has a potentially lethal downside: The compound is considered an oxidizer, meaning at an atomic level, it removes electrons from other substances in a chemical reaction. An explosion rocked Beirut on August 4. When heated to above 170 degrees Fahrenheit, ammonium nitrate begins to undergo decomposition. Beirut explosion: What is ammonium nitrate and how dangerous is it? NH 4 NO 3 (s) → NH 4 + (aq) + NO 3-(aq) The heat flow (q rxn) for this reaction is called the heat of solution for ammonium nitrate. This reaction isn’t the only one taking place, however. Solid ammonium nitrate decomposes on heating. For decades, Australia has produced, stored and used ammonium nitrate without a … The graphic in this article is licensed under a  Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License. It’s also used in some explosive mixtures which are used for mining and quarrying. But with rapid heating or detonation, a chemical reaction can occur that converts ammonium nitrate to nitrogen and oxygen gas and water vapor. Ammonium nitrate decomposition can be set off if an explosion occurs where it’s stored, if there is an intense fire nearby. It is widely used in fertilizers and explosives. Copper is a known sensitizer for ammonium nitrate (that is, NH4NO3 is now transformed into a sensitive explosive, probably due to the creation of NH4NO2 and at higher temperatures, other unstable intermediaries, so be very very wary).

It's also an explosive compound and is used around the world in mining and construction operations requiring detonations. Ammonium nitrate’s major use is as a fertiliser – this accounts for around 78% of its use (by volume) worldwide. It’s a source of nitrogen, important for the growth of plants. If the ammonium nitrate ignites, and the hard crust confines it, then the burn wave can transition to a detonation by a process known as deflagration to detonation transition. Ammonium nitrate provides both, intimately associated in each molecule. In the aftermath of the blast, videos show plumes of red-brown smoke and the apocalyptic extent of the destruction, with buildings leveled for miles. Ceric ammonium nitrate (CAN) is the inorganic compound with the formula (NH 4) 2 Ce (NO 3) 6. "It is generally kept under controlled conditions and modified volumes to minimize chances of explosion," says Brent Kaiser, a plant biologist at the University of Sydney. This also requires pressure to build up in a confined space, without being able to dissipate. On the Thermal Decomposition of Ammonium Nitrate. Ammonium nitrate is capable of absorbing water from the air at a relative humidity of 59.4 percent. It takes energy to do this, which is absorbed from the surroundings and makes the solution cold. However, its use in the field of propellants = pyrotechnics, unl ike potassium Show full articles without "Continue Reading" button for {0} hours. Ammonium nitrate is a chemical compound containing the element nitrogen (as well as hydrogen and oxygen) and is commonly used in agriculture as fertilizer. Nitrogen dioxide (NO₂) is a red, bad-smelling gas. Burning ammonium nitrate in an open field, for instance, isn't likely to result in an explosion, Rae said. Ammonium nitrate, which Lebanese authorities have said caused the devastating Beirut blast, is an odourless crystalline substance commonly used as … It may be considered the ammonium analog to potassium nitrate or saltpeter. As a fertilizer, the compound is applied as granules, and fused with ammonium sulfate to minimize the volatile nature of the compound. Facilities holding high quantities of the chemical are subject to inspection by the Department of Homeland Security. Ammonium lactate side effects. the apocalyptic extent of the destruction. The US cybersecurity and infrastructure security agency has also proposed a program to closely regulate the sale of transfer of ammonium nitrate. Plants rely on photosynthesis, converting sunlight to energy using chlorophyll.

Plants producing a solid ammonium nitrate product may employ all of the operations. Ammonium nitrate is an odourless crystalline substance that is naturally stable and used in fertilisers, but when mixed with other chemicals such as oil can create a potent explosive. The latter is what happened in the 2015 Tianjin explosion , which killed 173 people after flammable chemicals and ammonium nitrate were stored together at … Ammonium nitrate is the nitrate salt of the ammonium cation. The solution is then evaporated to remove excess water and obtain Ammonium nitrate content of 95-99% (depending upon … Ammonium has a chemical formula NH4+ and nitrate has the chemical formula NO3-. It can explode after exposure to contaminants or fuel oil and then heated, which sets off a cascade of reactions. The explosive force from the Beirut blast said to have been caused by the involvement of fireworks has been compared to that of the nuclear bomb at Hiroshima.. Approximately 60 percent of the ammonium nitrate produced in the U. S. is sold as a solid product. Balancing chemical equations. Ammonium nitrate (NH 4 NO 3) is produced by neutralizing nitric acid (HNO 3) with ammonia (NH 3 ). While ammonium nitrate is the result of a reaction between ammonia and nitric acid, ammonium sulphate is produced when ammonia reacts with sulfuric acid.

In these explosive mixtures, it acts as an oxidising agent, helping other materials burn. An ammonium nitrate explosion produces massive amounts of nitrogen oxides. This is the key difference between ammonium nitrate and ammonium sulphate. This orange-red, water-soluble cerium salt is a specialised oxidizing agent in organic synthesis and a standard oxidant in quantitative analysis. Ammonium nitrate decomposes in temperatures above 210 °C (410 °F). While ammonium nitrate is stable at the usual temperatures of its manufacture and purification, additives are often used reduce the hazards. To produce a solid product, the ammonium nitrate solution is concentrated in an evaporator or concentrator. The industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid: Explosions of ammonium nitrate fertilizer in storage or transportation are preventable accidents, Review on thermal decomposition of ammonium nitrate. This reaction is highly exothermic. However, its use in the field of propellants = pyrotechnics, unl ike potassium The unwanted reaction was detected when fumes were observed coming from the bag. When combined with fuel oils, ammonium nitrate creates a potent explosive widely used by the construction industry, but also by insurgent groups like the Taliban for improvised explosives. The blame for the explosion has been directed at 3,000 tons of ammonium nitrate that was being stored in a warehouse in Beirut’s port. Ammonium nitrate, which Lebanese authorities have said was the cause of the Beirut blast, is an odorless crystalline substance commonly used as a fertilizer that has been the cause of numerous industrial explosions over the decades. It’s not the only additional product: ammonia and nitrous oxide are amongst the others. But with rapid heating or detonation, a chemical reaction can occur that converts ammonium nitrate to nitrogen and oxygen gas and water vapor. Ammonium Nitrate/Fuel Oil (ANFO) mixtures provide a stable and powerful explosive that you can easily make in your garage: The most widely used dry blasting agent is a mixture of ammonium nitrate prills (porous grains) and fuel oil. At temperatures below around 300 °C, the decomposition mainly produces nitrous oxide and water: NH 4 NO 3 → N 2 O + 2H 2 O. It is also one of the main components in mining explosives. Ammonium nitrate, which Lebanese authorities have said caused the devastating Beirut blast, is an odourless crystalline substance commonly used as … This makes it effective at cooling small insulated containers such as coolers and lunch boxes. Evacuate the area in all directions for one (1) mile or more if any amount of ammonium nitrate is involved in a fire. Nitrogen is an essential element for this process and ammonium nitrate is particularly good, compared with other fertilizers, at delivering plants nutrients. In Australia, the storage and use of ammonium nitrate is monitored to prevent these types of explosions occurring, Kaiser said. The chemical reaction produces a concentrated form of ammonium nitrate, which produces prodigious amounts of heat. Ammonium nitrate is a crystal-like white solid which is made in large industrial quantities. When the two compounds are allowed to mix, the reaction lowers the surrounding temperature. Ammonium nitrate is a chemical compound containing the element nitrogen (as well as hydrogen and oxygen) and is commonly used in agriculture as fertilizer. When aqueous solutions of these two salts are mixed, a heavy, white precipitate of barium sulfate is formed by double decomposition. Eng., 1962, 70, 91; Bretherick, 5th Ed., 1995]. An ammonium nitrate explosion produces massive amounts of nitrogen oxides. For decades, Australia has produced, stored and used ammonium nitrate without a … When it comes into contact with water, the polar water molecules interfere with those ions and eventually make them disperse. 2NH 4 NO 3 → 2N 2 + O 2 + 4H 2 O. When sodium hydroxide is used, the chemicals should be added in … As ammonium nitrate is a salt, both the cation, NH 4 +, and the anion, NO 3 −, may take part in chemical reactions. All ammonium nitrate plants produce an aqueous ammonium nitrate solution through the reaction of ammonia and nitric acid in a neutralizer. If you want to learn more about the chemistry behind ammonium nitrate explosions, I’ve provided some useful links below. Ammonium Nitrate is commonly used as fertilizer in granule form, as it dissolves under moisture allowing Nitrogen to be released into the soil. Lead(II) nitrate react with ammonium hydroxide to produce lead(II) hydroxide and ammonium nitrate. Special OX: Possesses oxidizing properties. This gaseous ammonia is then added to concentrated nitric acid to form Ammonium nitrate. It's not clear what else may have been ignited or exploded in the blast -- or what was stored at the docks -- but Prime Minister Diab is expected to make this information known "soon," according to The Guardian. An explosion at a warehouse in the Port of Beirut on Tuesday killed more than 100 people and left more than 4,000 people injured. During the production of the chemical compound, ammonia gas essentially reacts with nitric acid, creating a great deal of heat and a concentrate solution. Mostly it does, but in a fast, violent reaction a small amount escapes unreacted. Ammonium nitrate is an odourless crystalline substance commonly used as a fertilizer that has been the cause of numerous industrial explosions over the decades. Additionally, in the explosion, not all of the ammonium nitrate is used up and exploded. In pure form, ammonium nitrate is a crystalline white solid that readily dissolves in water. The US Environmental Protection Agency, in conjunction with the Occupational Safety and Health Administration and the Bureau of Alcohol, Tobacco, Firearms, and Explosives lists a number of statutes and regulations involved in the manufacturing, processing and storage of ammonium nitrate. Anti- … You might have wonder what caused the plume of smoke seen after the explosion in Beirut to have an orange-red colour. This reaction isn’t the only one taking place, however. Ammonium nitrate is also known for its oxidizing powers. Kauffman said, in principle, ammonium nitrate should be highly explosive by itself, but it is not. NH 4 NO 3 can be prepared from the acid-base reaction between nitric acid and ammonia, described by the following chemical equation:. It … Despite having nitrogen as a common substance in both the salts, they have different physical and chemical properties. An ammonium nitrate explosion produces massive amounts of nitrogen oxides. Capable of detonation or explosive decomposition or explosive reaction but requires a strong initiating source or must be heated under confinement before initiation. "The idea in making any sort of explosive is to go from a high energy compound to a low energy one," explains Ian Rae, a professor at the University of Melbourne. Ammonium nitrate is a chemical compound produced in both solid and liquid form that is com - … It is widely used in many explosives used in the mining and construction sectors. Some of it decomposes slowly creating toxic gases like nitrogen oxides. An explosion of ammonium nitrate was responsible for the worst industrial accident in US history in 1947. It is widely used in many explosives used in the mining and construction sectors. The commercial grade contains about 34 percent nitrogen, all of which is in forms utilizable by plants; it is the most common nitrogenous component of artificial fertilizers. The products of the reaction are harmless -- they're found in our atmosphere -- but the process releases huge amounts of energy. The explosive potential of ammonium nitrate is well understood and has been used in numerous terrorist attacks including the Oklahoma City bombing of 1995. It degrades in storage with an exothermic reaction, so heat is produced. Ammonium nitrate consists of ionic bonds packed tightly together. Cerium (IV) ammonium nitrate ((NH 4) 2 Ce(NO 3) 6) is a one-electron oxidizing agent that is used for oxidative addition reactions of electrophilic radicals to alkenes, enabling intermolecular and intramolecular carbon-carbon and carbon-heteroatom bond formation.CAN also oxidizes secondary alcohols into ketones and benzylic alcohols into aldehydes. This graphic takes a look. (NFPA, 2010) General Description. "What happened today will not come to pass without accountability," Diab said. The thermal decomposition of ammonium nitrate to produce nitrogen, water and oxygen. Reports suggest over 2,700 tons of ammonium nitrate detonated. Its chemical formula is NH 4 NO 3 or N 2 H 4 O 3. He has also announced that Wednesday will be a national day of mourning in the country and the port and surrounding region has been declared a disaster zone. The hazards of AMMONIUM NITRATE have been well studied because of several extremely severe explosions [Chem. Evacuation is recommended if the initial (incipient) fire, not involving ammonium nitrate, becomes intense. Ammonium nitrate is commercially available both as a colorless crystalline solid and processed into prills for specific applications.
