Nitration of organic compounds with nitric acid is the primary method of synthesis of many common explosives, such as nitroglycerin and trinitrotoluene (TNT). [all data], Messer, De Lucia, et al., 1984 May, R.D. With more concentrated nitric acid, nitrogen dioxide is produced directly in a reaction with 1:4 stoichiometry: Upon reaction with nitric acid, most metals give the corresponding nitrates. If we look at the shape of the HNO3 molecule, it has a trigonal planar shape. Balance the equation HNO3 + Ca(OH)2 = Ca(NO3)2 + H2O using the algebraic method or linear algebra with steps. [36][37], In the 17th century, Johann Rudolf Glauber devised a process to obtain nitric acid by distilling potassium nitrate with sulfuric acid. Except where otherwise noted, data are given for materials in their, "wfna" redirects here. The red fuming nitric acid obtained may be converted to the white nitric acid. ; Looi, E.C. The two terminal NO bonds are nearly equivalent and relatively short, at 1.20 and 1.21 . CAS No. [20], The main industrial use of nitric acid is for the production of fertilizers. 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. The hydroxyl group will typically strip a hydrogen from the organic molecule to form water, and the remaining nitro group takes the hydrogen's place.

There is some disagreement over the value of the acid dissociation constant, though the pKa value is usually reported as less than 1. We start with a valid Lewis structure and then follow these general rules. In the case of a single solution, the last column of the matrix will contain the coefficients. [6][11], Nitric acid is normally considered to be a strong acid at ambient temperatures. [all data], Harwood, Jones, et al., 1993 Seco. ; Molina, L.T., Nitric acid (HNO3), a highly corrosive acid, is a very important chemical. [40] This process is based upon the oxidation of atmospheric nitrogen by atmospheric oxygen to nitric oxide with a very high temperature electric arc. It is highly corrosive and toxic. Magnesium, manganese, and zinc liberate H2: Nitric acid can oxidize non-active metals such as copper and silver. . Opt., 1979, 18, 24, 4152, https://doi.org/10.1364/AO.18.004152 In order to draw the lewis structure of HNO3, first of all you have to find the total number of valence electrons present in the HNO3 molecule.

Wlodek, S.; Luczynski, Z.; Wincel, H., So the concentration of hydronium ions is equal to 10 to the negative 1.50, which is equal to 0.032. Such distillations must be done with all-glass apparatus at reduced pressure, to prevent decomposition of the acid. [13] Although it reacts with graphite and amorphous carbon, it does not react with diamond; it can separate diamond from the graphite that it oxidizes.[14]. . Average mass 63.013 Da. Since nitric acid has both acidic and basic properties, it can undergo an autoprotolysis reaction, similar to the self-ionization of water: Nitric acid reacts with most metals, but the details depend on the concentration of the acid and the nature of the metal. Nitric acid was pumped out from an earthenware[43] pipe that was sunk down to the bottom of the pot. J. Quant. J. Mol. H3O plus and Cl minus.
