The main industrial use of nitric acid is for the production of fertilizers. Nitric acid is neutralized with ammonia to give ammonium nitrate. This application consumes 75–80% of the 26 million tonnes produced annually (1987). The other main applications are for the production of explosives, nylon precursors, and specialty organic compounds. [39]
Upon mixing of concentrated hydrochloric acid and concentrated nitric acid, chemical reactions occur. These reactions result in the volatile products nitrosyl chloride and chlorine gas: HNO 3 + 3 HCl → NOCl + Cl 2 + 2 H 2 O. as evidenced by the fuming nature and characteristic yellow color of aqua regia.
Red fuming nitric acid (RFNA) is a storable oxidizer used as a rocket propellant. It consists of nitric acid (H N O 3), dinitrogen tetroxide (N 2 O 4) and a small amount of water. The color of red fuming nitric acid is due to the dinitrogen tetroxide, which breaks down partially to form nitrogen dioxide. The nitrogen dioxide dissolves until the ...
It is the mercury(II) salt of nitric acid HNO 3. It contains mercury(II) cations Hg 2+ and nitrate anions NO − 3, and water of crystallization H 2 O in the case of a hydrous salt. Mercury(II) nitrate forms hydrates Hg(NO 3) 2 ·xH 2 O. Anhydrous and hydrous salts are colorless or white soluble crystalline solids that are occasionally used as ...
NO 2 is further oxidized in the gas phase during daytime by reaction with OH NO 2 + OH (+M) → HNO 3 (+M), where M denotes a third molecule required to stabilize the addition product. Nitric acid (HNO 3) is highly soluble in liquid water in aerosol particles or cloud drops. NO 2 also reacts with ozone to form nitrate radical NO 2 + O 3 → NO ...
It is a multi-step nitrogen fixation reaction that uses electrical arcs to react atmospheric nitrogen (N 2) with oxygen (O 2), ultimately producing nitric acid (HNO 3) with water. [1] The resultant nitric acid was then used as a source of nitrate (NO 3 − ) in the reaction HNO 3 + H 2 O H 3 O + + NO 3 − {\textstyle {\ce {HNO3 + H2O -> H3O ...
This reaction is the first step in the production of nitric acid: [13] 4 NH 3 + 7 O 2 → 4 NO 2 + 6 H 2 O. It can also be produced by the oxidation of nitrosyl chloride: 2 NOCl + O 2 → 2NO 2 + Cl 2. Instead, most laboratory syntheses stabilize and then heat the nitric acid to accelerate the decomposition.
The reaction produces fragments from the parent alkane, creating a diverse mixture of products; for instance, nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane are produced by treating propane with nitric acid in the gas phase (e.g. 350–450 °C and 8–12 atm).
