- To maximize the yield of nitric acid, the temperature is kept low (50 C) and the pressure high (9-10 atm) in the absorption tower. The absorption of nitrogen dioxide in water forming nitric acid is 99.9% efficient. Therefore the yield of nitric acid from ammonia is 95 x 0.999 = 94.9%. Some of the uses of nitric acid

Nitric Acid, OmniTrace Ultra® We are proud to offer the Omni Trace Ultra™ brand of high-purity acids, bases and water for low leveltrace metal analysis. AAS, GFAAS, ICP-OES and ICP-MStesting all require the highest levels of purity possible in theacids used to blank equipment and prepare samples. How is gold tested? A spot test for gold has been in use for decades. The sample is first treated with nitric acid . Other metals may react or dissolve in this acid, but gold will not. Car batteries contain sulfuric acid that helps in the release of electrons to create electricity. Writing Formulas for Acids.1. Add dilute nitric acid and excess ammonium molybdate solution. Heat to boiling. A yellow precipitate of ammonium arsenomolybdate (NH4)3AsO4.12MoO3, indicates arsenate. 2. Add excess dilute nitric acid, followed by silver nitrate solution. Filter off the precipitate. Name. Large. Perchloric acid. HClO4. ClO4 -. Perchlorate ion. 3.2 * 109. Hydroiodic acid. HI. Hydrogen sulfate ion. 2.4 * 101. Nitric acid.

Nitric acid (also known as aqua fortis and spirit of niter). Molecular formula : HNO3 (O= 76,17 %, N= 22,23 %, H= 1,6 %) Molar mass = 63,0128 ± 0,0012 g·mol-1 It is a highly corrosive strong mineral acid. Nitric acid is the primary reagent used for nitration - the addition of a nitro group, typically to an organic molecule.
