Nitric acid is the inorganic compound with the formula H N O 3. It is a highly corrosive mineral acid. [6] The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into oxides of nitrogen. Most commercially available nitric acid has a concentration of 68% in water.
May 13, 2024 · nitric acid, (HNO 3 ), colourless, fuming, and highly corrosive liquid (freezing point −42 °C [−44 °F], boiling point 83 °C [181 °F]) that is a common laboratory reagent and an important industrial chemical for the manufacture of fertilizers and explosives. It is toxic and can cause severe burns.
Nitric Acid is a inorganic compound with chemical formula HNO3. It is a highly corrosive mineral acid, fuming, colourless and plays a important role in the manufacture of fertilisers and explosives. It is also known as the spirit of niter and aqua fortis.
Almost all commercial quantities of nitric acid are manufactured by the oxidation of ammonia with air to form nitrogen oxides that are absorbed in water to form nitric acid. Because nitric acid has a maximum boiling azeotrope at 69 wt%, the processes are usually categorized as either weak (subazeotropic) or direct strong (superazeotropic).
Nitric acid, HNO 3, is a highly corrosive mineral acid and is also commonly used as a strong oxidizing agent. Nitric acid is normally considered to be a strong acid at ambient temperatures. Nitric acid can be made by reacting nitrogen dioxide, NO 2 , with water.
May 17, 2018 · The natural manner in which nitrates reach the soil involves the reaction of nitrogen gas and oxygen gas in the atmosphere to form nitrogen dioxide gas (NO2), which then reacts with atmospheric water, making nitric acid, which provides a natural source of nitrates in water and soil.
Nitric acid is formed by the reaction of both dinitrogen pentoxide (N 2 O 3) and nitrogen dioxide (NO 2) with water. If the solution contains more than 86 percent nitric acid, it is referred to as fuming nitric acid.

Nitric acid is a strong acid (highly dissociated in aqueous solution) and dilute solutions behave much like other mineral acids. Concentrated nitric acid is a strong oxidizing agent. Most metals dissolve to form nitrates but with the evolution of nitrogen oxides.
