The temperature of the solution is lower than the starting temperature of either component chemical. She writes about science and health for a range of digital publications, including Reader's Digest, HealthCentral, Vice and Zocdoc. Toxic oxides of nitrogen are produced in fires involving this material. Determine the amount of fertilizer necessary using the soil test results as a guide. It is highly soluble in water; heating of the water solution decomposes the salt to nitrous oxide (laughing gas). Ammonium nitrate is capable of absorbing water from the air at a relative humidity of 59.4 percent. Ammonium nitrate is an odorless, colorless or white, crystal salt produced by the reaction of ammonia and nitric acid. Ammonium nitrate and urea are such nitrogen containing solids. Soluble in water.Does not readily burn but will do so if contaminated with combustible material. [1] Large stockpiles of the material can be a major fire risk due to their supporting oxidation, and may also detonate, as Ammonium nitrate's solubility increases as the water temperature rises. CEO Compensation and America's Growing Economic Divide. Nutrients, such as nitrogen and phosphorus, are essential for plant and animal growth and nourishment, but the overabundance of certain nutrients in water can cause a number of adverse health and ecological effects.Nitrogen, in the forms of nitrate, nitrite, or ammonium, is a nutrient needed for plant growth. It is a very dangerous chemical used in fertilizer and explosives. Ammonium nitrate is a chemical compound whose chemical formula is NH 4 NO 3 (CAS#: 6484-52-2). Ammonium nitrate (NH4HNO3) — a white, water-soluble substance — is the main source of fertilisers and is also a popular industrial explosive. It is predominantly used in agriculture as a high-nitrogen fertilizer and is also used as a component of explosive mixtures in mining, quarrying, and civil construction. Ammonium nitrate is commercially prepared by mixing ammonia salt and nitric acid. Ammonium nitrate is an industrial chemical commonly used in fertilisers and as an explosive for quarrying and mining. It is quite soluble in water; its solubility at 20 o C is 150g/100ml. If large quantities of this material are involved in a fire, it may explode. Its chemical formula is NH4NO3, meaning it is a molecule made up of atoms of nitrogen, hydrogen and oxygen. Physical Properties. 1.0 Recommended Guidelines . A wide variety of ammonium nitrate water options are available to you, Monband Water Soluble Fertilizar Co.,Ltd is the only one company in the name of “water soluble fertilizer”. Accelerates the burning of combustible material. Usually about one-third of total nitrogen are organic nitrogen compounds, mostly urea. It also destroyed Texas City in 1947 and the Alfred P. Murrah Federal Building in Oklahoma City in 1995. It provides a sourceof nitrogen to plants, which increases growth and crop yields. [DBID] Caswell No. This is the nitrate of ammonia, and it has the following structure. At high temperatures it decomposes into nitrous oxide and water, while in highly basic aqueous conditions ammonia is evolved, leaving the nitrate ion in solution.. Nitric acid is produced when ammonium nitrate is reacted with either sulfuric or hydrochloric … It takes energy to do this, which is absorbed from the surroundings and makes the solution cold. It is most commonly used as … ; It has a trigonal crystal structure. Made up of nitric acid and ammonia, it is an oxidiser. The ammonium nitrate is soluble in water. The freshwater aquatic life guideline is based on the August, 2001 Report Update titled Water Quality Criteria for Nitrogen (Nitrate, Nitrite, and Ammonia) (Nordin and Pommen 2001), the Technical Appendix titled Ambient Water Quality Guidelines for Nitrate (Nordin and Pommen 1986 and the addendum to the technical appendix (Meays 2009). Extensive batch adsorption studies have been carried out to evaluate the removal efficiency of ammonium nitrogen (NH 4 -N) by biochars of diverse feedstocks and production temperatures. What is this information? The solubility increases to 1024g/100ml when the temperature is raised to 100 o; The dissolution of NH 4 NO 3 in H 2 O is highly endothermic. It takes energy to do this, which is absorbed from the surroundings and makes the solution cold. Ammonium nitrate is a crystalline solid having a white/grey colour. [1] Large stockpiles of the material can be a major fire risk due to their supporting oxidation, and may also detonate, as It is highly soluble in water and hygroscopic as a solid, although it does not form hydrates. The monster explosion that destroyed a good bit of Beirut was caused by the detonation of more than 2,700 tons of the fertilizer ammonium nitrate – a ghastly amount of one seriously scary chemical. Ammonium nitrate in gardens is made stable with other compounds. The temperature of the solution is lower than the starting temperature of either component chemical. The endothermic reaction between water and ammonium nitrate is used in chemical cold packs. While some heat is produced when the ammonium nitrate ions interact with the water molecules (i.e., an exothermic reaction), it is a lot less than what is needed for the water molecules to disperse the strong ionic bonds of the ammonium nitrate, so the overall process is an endothermic reaction, or one that absorbs energy from its surroundings. This can be prevented by keeping the relative humidity low, storing ammonium nitrate in a sealed container or combining it with other chemical compounds. Ammonium nitrate consists of ionic bonds packed tightly together. When heated, ammonium nitrate decomposes non-explosively into gases of oxygen, nitrogen, and water vapor; however, it can be induced to decompose explosively by detonation into nitrous oxide and water vapor. When it comes into contact with water, the polar water molecules interfere with those ions and eventually make them disperse. This should only be done under controlled, supervised conditions in a chemistry lab because ammonium nitrate can cause asphyxiation if too much of it is inhaled, and it can explode at high temperatures. The Ammonium Nitrate Code of Practice provides best practices for safe and secure ammonium nitrate storage and handling. The U.S. Supreme Court: Who Are the Nine Justices on the Bench Today? At room temperature and standard pressure ammonium nitrate exist as an odorless, white crystalline solid. (1975), ammonium (NH 4 +) is the predominant form (>90%) over ammonia (NH 3) in most of the water environment with pH < 8.2 and temperature < 28°C. Well, firstly there is the ionization that occurs when any ionic salt is dissolved in water….i.e. If you hurt yourself, you can mix the contents of the bag together and place it on the injured part of your body. Ammonium Nitrate (AN) is a valuable fertilizer that helps produce healthy food for Canadians, but it must be handled responsibly. Moreover, it occurs as a natural mineral in nature. Ammonium nitrate is only moderately toxic, and is safe to use as a fertilizer on food crops. Ammonium nitrate is a white, water-soluble, crystalline substance that has a melting point of 170°C. It is predominantly used in agriculture as a high-nitrogen fertilizer. 15245-12-2 ..., pests, disease and low bearing are often the result. An excess of nitrate in water may result in eutrophication.This causes an overgrowth of algae, which depletes oxygen to levels that are too low for fish.. Ammonium nitrate appears as a white solid at room temperature and easily dissolves in water. Ammonium nitrate is a chemical compound whose chemical formula is NH 4 NO 3 (CAS#: 6484-52-2). Once ammonium nitrate becomes molten (particularly if confined) the risk of an explosion increases. Temperatures can drop to 2 or 3 degrees Celsius very rapidly. The force of the ammonium nitrate explosion is provided by the rapid generation of gas as it breaks down. Ammonium nitrate is a colourless crystalline substance (melting point 169.6 °C [337.3 °F]). Ammonium nitrate dissolves in water with an endothermic reaction, a chemical reaction that consumes heat rather than releasing it. Does not readily burn but will do so if contaminated with combustible material. The exact concentration depends on protein application of the population.
