If decomposition happens at supersonic rates, this leads to a shockwave characteristic of a detonation. Todays news has been dominated by the terrible explosion in Beirut, Lebanon. To use as an explosive or a blasting reagent, $\ce{NH4NO3}$ is mixed with fuel oil, which is called ammonium nitrate fuel-oil (ANFO; Ref.1). When nitrate is leached, it must be accompanied by an equivalent amount of cations to maintain charge balance. Clay particles usually have negative charges because of unsatisfied valences at the crystalline edges of the silica and alumina plates. This solution contains a swarm of ions a portion of which are cations trying to balance the surface charges. WebAmmonium nitrate melts at 337 deg F (170 deg C) and begins to undergo decomposition when molten. The ammonium is then nitrified within 23weeks. However, if it is contaminated with impurities, the risk of it detonating increases. Copyright 2023 Elsevier B.V. or its licensors or contributors. Short of that, NH4NO3 is a relatively weak explosive, but it comes in great quantities, hence the effect. This concentrated solution is further concentrated to obtain 9294% solution in a vacuum concentrator. In other words, they will fill the cup with their batch of mixed ANFO and weigh it. To write balanced equations for the reactions studied. In Europe ammonium nitrate or calcium ammonium nitrate (CAN) is widely used. Removal of nitrate from the soil by leaching has several consequences. Thus, we actually have both an oxidising and a reducing agent in the salt: the former is the nitrate anion and the latter is the ammonium cation. It is known that ammonium nitrate decompose exothermically when heated to form nitrous oxide and water. Even if the AN was contaminate free under normal conditions, anything in the area can become a fuel source including the containers themselves, fire debris, smoke, soot, collapsed building parts, etc. Task 2 Decomposition or explosion? might have melted the cover, and FGAN remnants could have been in the pit. When there are population centers nearby, it may be safer to store ammonium nitrate outside provided that it is sequestered from sources of heat, combustion, or hot work (operations involving open flames or producing heat and/or sparks, such as welding). The hydroxides of Group IA and barium are soluble. However, it is a strong oxidizing agent that can detonate under certain conditions such as temperature, fire, confinement, and presence of impurities (e.g., $\ce{KCl}$), which can be act as a promoter to detonate (Ref.2). Yes. When the ammonium nitrate stores exploded, a white condensation cloud spread out in a sphere from the site, followed by a huge plume of red-orange smoke rising from the hanger. Be sure to mix the solutions well. The heat of reaction is utilized for evaporation and 8083% ammonium nitrate solution is obtained. 2NH 4 NO 3 2N 2 + 4H 2 O + O 2. WebAmmonium nitrate | NH4NO3 or H4N2O3 | CID 22985 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. The ideal mixture, i.e., the oxygen-balanced mixture, consists of 3 moles of ammonium nitrate and one mole of fuel oil. This reaction takes place at a temperature of over 300C. The external surface area of 1g of colloidal clay is at least 1000 times that of 1g of coarse sand. Web1. The relative activities of metals can be tabulated in an activity series, ranking the metals by relative ease of oxidation. The coating of products may also create some particulate emissions during mixing in the rotary drums. <> Rangi CS GO. With a greater surface area, the chemical activity is greater for fine-textured soils. Duress at instant speed in response to Counterspell. As an example, potassium chlorate decomposes when heated to yield potassium chloride and oxygen gas. If you cannot detect anything, make sure that you used the correct concentrations of acid and base. This paper1 notes that the irreversible decomposition of ammonium nitrate occurs at the temperature range of $\pu{230-260 ^\circ C}$. @JasonC There are many factors, not just heat. Can the Spiritual Weapon spell be used as cover? So, now we know that when we mix the ammonium nitrate with the fuel oil, we need to do it in this proportion if we want an oxygen balanced reaction. 15.2). Web1. Worldwide, urea is by far the most commonly used form of nitrogen fertilizer. Give a balanced equation for the decomposition reaction. Layers of silica tetrahedrons (silica atom with a four-sided oxygen configuration) and aluminum octahedron (aluminum atom within a six-sided oxygen or hydroxyl structure) are bound together by shared oxygen atoms. In Beirut we saw that there was already a fire burning for a significant amount of time before the explosion, as well as a smaller explosion that occurred < 30 seconds before the main one. It is important to achieve an oxygen balance within the explosive. Ammonium (NH4+) has a positive charge and is an exchangeable cation. Using the VSEPR theory and the diagrams above, -state and explain the geometries of the NH 4 + and NO 3 ions shown. In its pure form, ammonium nitrate isnt usually explosive in fact, its safe to handle. 46002 [, Principles and Applications of Soil Microbiology (Third Edition), Extraction Techniques and Applications: Biological/Medical and Environmental/Forensics, Comprehensive Sampling and Sample Preparation. For example, in the first reaction given above, elemental lead is oxidized to lead(II) and copper is reduced from copper(II) to elemental copper. All explosives applications rely on the large volume of gas released on vigorous detonation of the ammonium nitrate component (Eq. 2. Part of my motive for asking is the news today (Aug 4, 2020) of an explosion in Beirut. \[\ce{Sn(s) + HCl(aq) -> H2(g) + SnCl2(aq)} \quad \quad \quad \text{______ >______}\], \[\ce{Au (s) + Sn(NO3)2 (aq) ->} \text{NR} \quad \quad \quad \quad \text{______ >______}\], \[\ce{Au(s) + HCl ->} \text{NR} \quad \quad\quad \quad \text{______ >______}\], \[\ce{Zn (s) + Sn(NO3)2 (aq) -> Zn(NO3)2 (aq) + Sn (s)} \quad \text{______ >______}\]. Combination Reactions (also called Synthesis Reactions) occur when two or more substances, elements or compounds, combine to form one new substance. The common cations adsorbed by clay surfaces are H+, Al3+, Ca2+, Mg2+, K+, and Na+. I object. And from section 4.3, a few detonation scenarios: Based on the location of the pile and the properties of the bin along with the circumstances of other fire induced incidents, one possible scenario is that a period of contamination with soot and other organics Planned Maintenance scheduled March 2nd, 2023 at 01:00 AM UTC (March 1st, We've added a "Necessary cookies only" option to the cookie consent popup. When contaminants are added to AN, the To perform and observe the results of a variety of chemical reactions. Two electrons are transferred from lead to copper in this process: \[ \ce{Pb (s) -> Pb^{2+} (aq) + 2 e^-} \quad \quad \text{oxidation of lead}\], \[ \ce{Cu^{2+} (aq) + 2e^- -> Cu (s)} \quad \quad \text{reduction of copper}\]. Ammonium nitrates major use is as a fertiliser this accounts for around 78% of its use (by volume) worldwide. Warm the test tube gently by passing it back and forth through a burner flame. A second method for phosphorus immobilization is precipitation. Seed materials, zinc, and other Using the VSEPR theory and the diagrams above, -state and explain the geometries of the NH 4 + and NO 3 ions shown. As an example, potassium chlorate decomposes when heated to yield potassium chloride and oxygen gas. Divalent cations (i.e., Ca2+ and Mg2+) tend to have a small ionic radius and thus allow the particles to be close together and form a strong bond. Note: Method 1 is of less importance now and used less because formaldehyde can be a safety hazard if not used properly. gases like nitrogen oxides. Clays are composed of plate-like crystalline units that are laminated to form individual particles. This is an important consideration because wastewater could have a significant quantity of monovalent cations such as sodium from salt and water softeners. During the fire, soot from the smoke and also collapsing wood 3. S.B. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. A further environmental hazard may be the production of carcinogenic nitrosamines from reactions between nitrite and secondary amines. Prill towers and granulators are the largest sources of particulates. Solid ammonium nitrate decomposes on heating. How can I recognize one? $$\ce{NH4NO3 -> N2O + 2H2O } \quad \Delta H = \pu{-59 kJ/mol} \tag3$$, $$\ce{NH4NO3 -> 1/2N2 + NO + 2H2O } \quad \Delta H = \pu{-2597 kJ/mol} \tag4$$, $$\ce{NH4NO3 -> 3/4N2 + 1/2NO2 + 2H2O } \quad \Delta H = \pu{-944 kJ/mol} \tag5$$, $$\ce{2NH4NO3 -> 2N2 + O2 + 4H2O } \quad \Delta H = \pu{-1057 kJ/mol} \tag6$$, $$\ce{8NH4NO3 -> 5N2 + 4NO + 2NO2 + 16H2O } \quad \Delta H = \pu{-600 kJ/mol} \tag7$$. React these iron oxide, ammonium nitrate, and sucrose. Web1. Heating also poses a danger: ammonium nitrate decomposes at around 230C, and can explode when heated to between 260300C if its confined. For example, one of the deadliest industrial incidents in US history occurred on April 16, 1947, in Texas City, Texas where an $\ce{NH4NO3}$ explosion involving $\pu{2300 tons}$ of $\ce{NH4NO3}$ caused 581 fatalities and thousands of injuries. ________>________>________>________>________, most active (most easily oxidized) to least active. Please send comments or suggestions on accessibility to the site editor. Fractured crystalline edges expose oxygen and hydroxyl groups that present a net negative charge. Concentrated ammonium nitrate solution is then sprayed into the granulator along with a regulated quantity of limestone powder and the recycle fines from the screens. The Journal of Physical Chemistry, Guy Marlair, Marie-Astrid Kordek, "Safety and security issues relating to low capacity storage of AN-based fertilizers,", Zhe Han, "Thermal Stability Studies of Ammonium Nitrate,", Alex M. Djerdjev, Pramith Priyananda, Jeff Gore, James K. Beattie, Chiara Neto, Brian S. Hawkett, "The mechanism of the spontaneous detonation of ammonium nitrate in reactive grounds,". Using the VSEPR theory and the diagrams above, -state and explain the geometries of the NH 4 + and NO 3 ions shown. Carbonates, Chromates and Phosphates are insoluble. High concentrations of nitrate may also be associated with methemoglobinemia (blue-baby syndrome), which is now quite rare. Arrhenius plots for these ammonium nitrate composite systems were constructed. Hold a strip of moistened red litmus paper in the tube without letting it come in contact with the sides of the tube and note any color changes to the paper. Beirut explosion: What is ammonium nitrate and how dangerous is it? Thus, soils are also depleted of cations when nitrate is leached. @MuhammadAbbass As many of the answers state, ammonium nitrate is both an oxidiser. Current Federal regulations require that drinking water contain<10mg NO3-N L1 (read as mg nitrate nitrogen per liter). The exploded $\ce{NH4NO3}$ was coated with (carbon based) wax to prevent caking (See equation $(8)$ above). Biological fates for nitrate include its assimilation by plants and microorganisms and its use in the anaerobic, reductive processes discussed next. Microprills can form and clog orifices, increasing fine dust loading and emissions. Therefore, the number that you need to give to your blaster is 0.42 lb. drop pipe from the elevator mechanism) was followed by about 5 to 6 minutes of intense radiant heating It is also used in explosives (especially as an oil mixture) for blasting rocks and in mining. Dissolved cations form an outer layer around the clay surface (Hiemenz, 1986). In principle these additives (urease inhibitors or nitrification inhibitors) should decrease the losses associated with nitrate by decreasing the quantity in soil. As for the question whether the disaster of Beirut was an deflagration or a detonation: which term is applicable depends solely on the rate of decomposition and the resulting velocity of the front. Unless otherwise indicated dispose of all waste in the waste container provided. You'll need to be patient balancing this equation! When the ammonium nitrate stores exploded, a white condensation cloud spread out in a sphere from the site, followed by a huge plume of red-orange smoke rising from the hanger. In addition to the production of toxic gas, the energy release is reduced. (4 marks) Ques. It was at a seaport, too, meaning there were probably a lot of nearby things to act as fuel sources. Because of its explosiveness, $\ce{NH4NO3}$ is associated with various hazards including fire and explosion, which have occurred repeatedly in the past (more than 70 incidents during 20th century, more than half of them occurred in the US soil). A number of additives are available commercially that retard either urea hydrolysis or nitrification, so retaining a greater proportion of N from fertilizer in the ammonium form and decreasing the amount as nitrate. Hold a small strip of magnesium metal (used in flashbulbs and fireworks) in your crucible tongs and ignite the metal in the hot portion of a burner flame. Thus, in practice, the difference between urea and ammonium nitrate or CAN in terms of impact on soil nitrate is fairly small. : And then, we can calculate the molecular weight of the ammonium nitrate and the fuel oil. Nitrate has a negative charge and will remain in the soil solution. greatly increase the radiant heat flux by raising the temperature of the burning wood. Mathew's answer below has some more reaction formulas with enthalpy changes and other info. concrete pit walls, might have provided the conditions for a solid phase DDT beginning in the bottom of I attached PDF file if Ref.2 if a reader is interested in how explosions happen during right conditions (otherwise, it is a broad field to explain). What does a search warrant actually look like? Ammonium nitrate (NH4NO3) is produced by neutralizing nitric acid (HNO3) with ammonia (NH3). Record your observations on the data page as you complete each reaction. The surface of the However, if it is contaminated with impurities, the risk of it detonating increases. The College of Earth and Mineral Sciences is committed to making its websites accessible to all users, and welcomes comments or suggestions on access improvements. From: Encyclopedia of Analytical Science (Second Edition), 2005, P.S. This reaction takes place at a temperature of over 300C. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. They also further noted that beyond $\pu{280 ^\circ C}$, $\ce{NH4NO3}$ is capable of rapid, self-accelerating decomposition (to the point of detonation). They will compare that weight to the weight that they have been given as the specified weight. ignited from above, undergoing a gas-phase deflagration-to-detonation transition (DDT) in the Ammonium nitrate is composed of two polyatomic ions identify the different type(s) of bonding within its structure. the surface of the FGAN pile. Are these explosions also detonations? Plants producing a solid ammonium nitrate product may employ all of the operations. The carbonates, chromates and phosphates of Group IA and ammonium are soluble. WebThe chemical equation described in section 4.1 is balanced, meaning that equal numbers of atoms for each element involved in the reaction are represented on the reactant and product sides. It is known that ammonium nitrate decompose exothermically when heated to form nitrous oxide and water. Examples and descriptions of each reaction type appear in the following section. When a fire or a heat source is sequestered in a closed container of ammonium nitrate (e.g., tank, shipping container), the reaction can transition to a violent explosion in a phenomenon known as deflagration-to-detonation transition, or DDT. For 3 moles of NH 4 NO 3 : 3*80.05 = 240.15 g, For 1 mole of CH 2: 1*14.03 = 14.03 g, The molecular weight of ANFO is, therefore: 240.15 + 14.03 = 254.18 g, NH 4 NO 3 : (240.15 / 254.18) *100 = 94.5% by weight, CH 2 : (14.03 / 254.18) * 100 = 5.5% by weight. Nitrates and nitrites are used to cure meats and to develop the characteristic flavor and pink color, to prevent rancidity, and to prevent growth of Clostridium botulinum spores in or on meats. Although you know the weight of each ingredient in the mix, you dont know the density of the mix. Additives such as magnesium nitrate or magnesium oxide may be introduced into the melt prior to solidification to raise the crystalline transition temperature, act as a desiccant (removing water) or lower the temperature of solidification. Ammonium nitrate is shock sensitive when mixed with titanium, tin, or aluminum. Use 1 mL of each solution unless otherwise specified. Task 2 Decomposition or explosion? When one thinks of fire and dissects the requirements of a fire into a fuel and an oxidiser, this is in chemical terms only a different way of determining an oxidising agent and a reducing agent in a redox reaction. explosion, Rae said. Explosives applications have been varied from blends with nitroglycerin to make this safer for use in mines, to admixtures with smokeless powders and nitro compounds such as trinitrotoluene, to the more recent developments of blends of low-density ammonium nitrate prills with fuel oil (so-called ANFO explosives), or in water slurries with metal powder boosters to produce a low-cost heaving power explosive [58]. %PDF-1.4 Wszystko, co powiniene o nich wiedzie. It is known that ammonium nitrate decompose exothermically when heated to form nitrous oxide and water. These aren't the only ways it can explode, but they are a few examples of the types of conditions that could lead to explosion. Jak wczy auto bunnyhop? Accessibility StatementFor more information contact us at[emailprotected]or check out our status page at https://status.libretexts.org. I thought ammonium nitrate was an oxidizer that needed to be mixed with fuel to form a high explosive (e.g., ANFO). Thus, the nitrogen in nitrate will, as part of a redox reaction reduce its oxidation state by taking up electrons. Examples are shown in Figures 5-7. Decomposition, pitting, or the disappearance of a solid metal. Emissions from ammonia and nitric acid occur primarily when they form solutions (neutralizers and concentrators), and when they are used in granulators. Does Cast a Spell make you a spellcaster? Give a balanced equation for the decomposition reaction. Its also used in some explosive mixtures which are used for mining and quarrying. ANFO is typically yellowish spheres that dissolve slowly in water. The determined percentage ammonium nitrate can be converted to %N by multiplying the percentage ammonium nitrate by 0.349978. Make sure that you observe the results of every reaction even if you didnt actually mix the chemicals yourself. 2. Ammonium nitrate is reactive and incompatible with several organic and inorganic compounds. and exothermic decomposition reactions that take place with increasing temperature. Why or why not? Type of Chemical Reaction: For this reaction we have a decomposition reaction. We will need to mix 2.6 ft3 of ammonium nitrate with that gallon of fuel oil. Calcium ammonium nitrate (CAN) production process. FGAN storage area can include ignitable liquids, finely divided metals or organic materials, chloride You will use 1 mL of solution in many of the reactions; estimate this by drops (typically 12-15 drops from the reagent bottle dispenser) or by measuring 1 mL once in your graduated cylinder and then transferring it to a test tube to determine how far it fills the test tube. The primary reaction when it breaks down produces nitrogen, water vapour and oxygen. Because it is an anion, nitrate is easily leached. decomposition reactions become increasingly more complex. What are the other chemical substances that are formed in the process of making ammonium nitrite? Be sure to include the states of all compounds in your equations (solid, liquid, aqueous, or gas). Displacement reactions are also classified as oxidation-reduction reactions. Nitrate that leaches eventually enters ground and surface waters, where it may have potentially adverse environmental effects. The nitric acid is titrated with a standardized sodium hydroxide solution to a phenolphthalein endpoint or a pH endpoint. NH4NO3 - > 2H2O + N2O, However a passing shockwave can induce this decomposition in a large quantity of ammonium nitrate at once, which is a detonation. Write a balanced formula equation with state labels for each reaction. ANFO versus Emulsion The solubility of the substances. What role does ammonium play in the explosion of ammonium nitrate? At some point around 5 to 6 minutes before the detonation, the character of the fire changed, according to Possible sources of contamination in an Most reactions take place on surfaces adjacent to soil pores. In the context of Beirut explosion, the question that raised was "when did ammonium nitrate reached detonation temperature, and why did it suddenly explode?". What are the other chemical substances that are formed in the process of making ammonium nitrite? Why exactly does molten NaCl explode, when it is poured into water? NH 4 NO 3: molecular weight = 80.05 g/mol CH 2: molecular weight = 14.03 g/mol The ideal mixture, i.e., the oxygen-balanced mixture, consists of 3 moles of ammonium nitrate and one mole of fuel oil. Mixtures containing urea can also explode. holes cut in the partition between the bins. According to Ref.2, during the explosion, following exothermic reaction would take place (hydrocarbon is represented by $\ce{CH2}$): $$\ce{3NH4NO3 + CH2 -> 3N2 + 7 H2O + CO2} \quad \Delta H = \pu{-4017 kJ/kg} \tag1$$. Scenario 2: Detonation in heated FGAN along exterior wall exposed to fire. As this is nitrogens lowest known oxidation state, it cannot act as an oxidising agent but it can act as a reducing agent see for example the Ostwald process in which ammonia (also in the $\mathrm{-III}$ oxidation state) is burned in an oxygen atmosphere ultimately leading to nitric acid. What is the purpose of this D-shaped ring at the base of the tongue on my hiking boots? Without fuel oil, can be detonated under certain conditions. Rao, in Encyclopedia of Toxicology (Third Edition), 2014. Word equation: Ammonium nitrate Nitrogen gas + Oxygen gas + Water. The John A. Dutton e-Education Institute is the learning design unit of the College of Earth and Mineral Sciences at The Pennsylvania State University. High concentrations of nitrate in surface waters can lead to eutrophication (the sudden enrichment of natural waters with excess nutrients which can lead to the development of algal blooms and other vegetation). have come in contact with molten FGAN. Reportedly there were fireworks stored in the same warehouse as the AN in Beirut: So ammonium nitrate by itself is considered a low explosive, but has potential to detonate (ie, be a high explosive) under the right conditions? Suppose that each of the following pairs of aqueous solutions is combined. Observe. For applications in March, when soil temperatures were lower, the transformations were slower but the trends the same. The sulfides of Group IA, ammonium, calcium, and barium are soluble. However, if it is contaminated with impurities, the risk of it detonating increases. The final solid products are screened and sized, and off-size particles are dissolved and recycled through the process. If no discernable initial change is noted, let the reaction mixture stand for at least five to ten minutes before observing again. 2H 2(g) + O 2(g) 2H 2O(l) Decomposition Reactions occur when a compound breaks apart to yield two or more new substances. We can calculate the density of ANFO mixed to this ratio. 2. It does decompose ENDOTHERMICALLY, so it's not self propagating, and is not a low explosive: From most active (most easily oxidized) to least active: Now use the above results to write products for the reactions below. Addiscott, in Encyclopedia of Soils in the Environment, 2005. DR.James G. Speight, in Environmental Inorganic Chemistry for Engineers, 2017. In this review data from the literature on thermal decomposition of ammonium nitrate (AN) and the effect of additives to their thermal decomposition are summarized.
