Nitric acid (HNO3) is a strong and highly corrosive mineral acid with the chemical formula HNO3. It is a colorless liquid with a pungent odor and is a key chemical in various industrial and laboratory applications. Nitric acid is widely used in the production of fertilizers, explosives, and chemicals, including nitrate salts and plastics. In the laboratory, it is a common reagent for various chemical reactions and analyses. Nitric acid also plays a vital role in metal processing, particularly for etching and cleaning metals, as well as in the production of electronics and semiconductors. Its corrosive properties, reactivity, and versatility make nitric acid a fundamental compound in numerous industrial processes and scientific research.
Nitric Acid
Application Nitric acid is the inorganic compound with the formula HNO3. 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. When the solution contains more than 86% HNO3, it is referred to as fuming nitric acid. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as red fuming nitric acid at concentrations above 86%, or white fuming nitric acid at concentrations above 95%. Nitric acid is the primary reagent used for nitration â?? the addition of a nitro group, typically to an organic molecule. While some resulting nitro compounds are shock- and thermally-sensitive explosives, a few are stable enough to be used in munitions and demolition, while others are still more stable and used as pigments in inks and dyes. Nitric acid is also commonly used as a strong oxidizing agent.
The main industrial use of nitric acid is it is used for the production of fertilizers. The other main applications are for the production of explosives, nylon precursors, and specialty organic compounds. It has also been used in various forms as the oxidant in liquid fueled rockets. Nitric Acid is also used in metal processing as an oxidant and used as an analytical reagent in elemental analysis. It is also used in low concentrations in wood working, for artificially aging pine and maple. Nitric Acid is also used in the cleaning industry as an etchant, degreaser and cleaning agent.
