Anhydrous nitric acid is a colorless mobile liquid with a density of 1.512g/cm3 that solidifies at 42C (44F) to form white crystals[clarification needed]. In this process, anhydrous ammonia is oxidized to nitric oxide, in the presence of platinum or rhodium gauze catalyst at a high temperature of about 500K (227C; 440F) and a pressure of 9 standard atmospheres (910kPa). One specification for white fuming nitric acid is that it has a maximum of 2% water and a maximum of 0.5% dissolved NO2. This means that the nitric acid in diluted solution is fully dissociated except in extremely acidic solutions. The major hazard posed by it is chemical burns, as it carries out acid hydrolysis with proteins (amide) and fats (ester), which consequently decomposes living tissue (e.g. Reaction with non-metallic elements, with the exception of silicon and halogens, usually oxidizes them to their highest oxidation states as acids with the formation of nitrogen dioxide for concentrated acid and nitrogen oxide for dilute acid. [21] Ultrapure trace metal grade acid is required for such determination, because small amounts of metal ions could affect the result of the analysis. CopyCopied, InChI=1S/HNO3/c2-1(3)4/h(H,2,3,4) It can also be used in combination with hydrochloric acid as aqua regia to dissolve noble metals such as gold (as chloroauric acid). [1]. [30] It was also described by works attributed to Albert the Great and Ramon Lull, who prepared it by distilling a mixture containing niter and green vitriol and called it "eau forte" (aqua fortis). A solution of nitric acid and alcohol, Nital, is used for etching of metals to reveal the microstructure. [10], Although chromium (Cr), iron (Fe), and aluminium (Al) readily dissolve in dilute nitric acid, the concentrated acid forms a metal-oxide layer that protects the bulk of the metal from further oxidation. Depending on the acid concentration, temperature and the reducing agent involved, the end products can be variable. The presence of small amounts of nitrous acid (HNO2) greatly increases the rate of reaction. Another early production method was invented by French engineer Albert Nodon around 1913. 57.97%, Nitric Acid 42.03% Boiling Point: Approximately 100C Density: 1.26 Melting Point: Approximately 0C Color: Colorless to light yellow liquid Physical State: Liquid pH Range: Solubility Information: Miscible Shelf Life: 24 Months Storage: Ambient DOT: UN2031, NITRIC ACID,, Chemical name: Nitric acid Material form: Liquid Density (g/cm3): 1.42 Molecular weight: 63.01 Molecular formula: HNO3 Chemical purity: =65% (T) UN Number: UN 2031, 65% w/w Composition: Nitric Acid 65.25%, Water 34.75% Boiling Point: 120.5C Density: 1.45 Color: Colorless to light yellow liquid Physical State: Liquid pH Range: Solubility Information: Miscible Shelf Life: 24 Months Storage: Ambient DOT: UN2031, NITRIC ACID, 8, P.G. 1997-2022 LUMITOS AG, All rights reserved, https://www.chemeurope.com/en/encyclopedia/Nitric_acid.html, Your browser is not current. In December 2007, a Taiwan-bound freighter carrying 2,000 tons of nitric acid sank off the shore of South Korea. skin and flesh). It boils at 83C (181F). We Believe You Are Important, How Can We Help? Since nitric acid is an oxidizing agent, hydrogen (H2) is rarely formed. Reaction with non-metallic elements, with the exceptions of nitrogen, oxygen, noble gases, silicon, and halogens other than iodine, usually oxidizes them to their highest oxidation states as acids with the formation of nitrogen dioxide for concentrated acid and nitric oxide for dilute acid. Low ppb metal impurities. It has additional uses in metallurgy and refining as it reacts with most metals, and in organic syntheses.

Resistance was about 3 ohms per cubic meter and the power supplied was around 10 volts. Only magnesium (Mg) and calcium (Ca) react with cold, dilute nitric acid to give hydrogen: Although chromium (Cr), iron (Fe) and aluminium (Al) readily dissolve in dilute nitric acid, the concentrated acid forms a metal oxide layer that protects the metal from further oxidation, which is called passivation. Depending on the acid concentration, temperature and the reducing agent involved, the end products can be variable. For this reason, heavy corrosion can be expected and should be guarded against by the appropriate use of corrosion resistant metals or alloys. Concentrated nitric acid stains human skin yellow due to its reaction with the keratin. The industrial production of nitric acid from atmospheric air began in 1905 with the BirkelandEyde process, also known as the arc process.

Further concentration involves distillation with sulfuric acid which acts as a dehydrating agent. Microsoft Internet Explorer 6.0 does not support some functions on Chemie.DE. Dilute nitric acid behaves as a typical acid in its reaction with most metals. Find out how LUMITOS supports you with online marketing. [18], Nitric acid has been used in various forms as the oxidizer in liquid-fueled rockets. [8], The dissolved NOx is readily removed using reduced pressure at room temperature (1030minutes at 200mmHg or 27kPa) to give white fuming nitric acid. [15], Dilute nitric acid may be concentrated by distillation up to 68% acid, which is a maximum boiling azeotrope. Yields of up to approximately 45% nitric oxide were obtained at 3000C, and less at lower temperatures. Nitric acid is used either in combination with hydrochloric acid or alone to clean glass cover slips and glass slides for high-end microscopy applications. : TWA 2 ppm (5 mg/m 3 ). The nitric oxide is cycled back for reoxidation. The formation of this protective layer is called passivation.

In the laboratory, nitric acid can be made by thermal decomposition of copper(II) nitrate, producing nitrogen dioxide and oxygen gases, which are then passed through water to give nitric acid. Many explosives, such as TNT, are prepared this way: Either concentrated sulfuric acid or oleum absorbs the excess water. Nitric acid is subject to thermal or light decomposition and for this reason it was often stored in brown glass bottles: This reaction may give rise to some non-negligible variations in the vapor pressure above the liquid because the nitrogen oxides produced dissolve partly or completely in the acid. Red fuming nitric acid, or RFNA, contains substantial quantities of dissolved nitrogen dioxide (NO2) leaving the solution with a reddish-brown color. Being a powerful oxidizing agent, nitric acid reacts with many non-metallic compounds, sometimes explosively. Also, in ICP-MS and ICP-AES techniques, nitric acid (with a concentration from 0.5% to 2.0%) is used as a matrix compound for determining metal traces in solutions. Commercially available aqueous blends of 5-30% nitric acid and 15-40% phosphoric acid are commonly used for cleaning food and dairy equipment primarily to remove precipitated calcium and magnesium compounds (either deposited from the process stream or resulting from the use of hard water during production and cleaning). : 63.01 NFPA#: 3-0-3 Specific Gravity: 1.408 DOT: 8/5.1/II Descriptions: Trace metal grade. Some precious metals, such as pure gold and platinum-group metals do not react with nitric acid, though pure gold does react with aqua regia, a mixture of concentrated nitric acid and hydrochloric acid. Being a strong oxidizing agent, nitric acid can react violently with many compounds. Bubbling nitrogen dioxide through hydrogen peroxide can help to improve acid yield. His method produced nitric acid from electrolysis of calcium nitrate converted by bacteria from nitrogenous matter in peat bogs. It is available as 99.9% nitric acid by assay. The fluoride creates a metal fluoride layer that protects the metal.

This procedure can also be performed under reduced pressure and temperature in one step in order to produce less nitrogen dioxide gas. Nitric acid is a corrosive acid and a powerful oxidizing agent. Nitration of organic compounds with nitric acid is the primary method of synthesis of many common explosives, such as nitroglycerin and trinitrotoluene (TNT). Cast iron cathodes were sunk into the peat surrounding it. If proteins that contain amino acids with aromatic rings are present, the mixture turns yellow.

Being a powerful oxidizing acid, nitric acid reacts with many organic materials, and the reactions may be explosive. Corrosive to metals. Reactions of nitric acid with many organic compounds, such as turpentine, are violent and hypergolic (i.e., self-igniting). An inhibited fuming nitric acid, either White Inhibited Fuming Nitric Acid (IWFNA), or Red Inhibited Fuming Nitric Acid (IRFNA), can be made by the addition of 0.6 to 0.7% hydrogen fluoride (HF). Nitric acid can act as a base with respect to an acid such as sulfuric acid: The nitronium ion, NO+2, is the active reagent in aromatic nitration reactions. This is subsequently absorbed in water to form nitric acid and nitric oxide.
