Nitric Acid 65%
Nitric Acid 65% (CAS 7697-37-2) is a strong, corrosive mineral acid essential for various industrial syntheses and processes.
Description
Nitric Acid, with the chemical formula HNO3, is a highly corrosive and fuming strong mineral acid, typically encountered as a clear to yellowish liquid. At a concentration of 65%, it exhibits significant oxidizing properties and is widely regarded as one of the most commercially important inorganic acids. Its unique chemical characteristics, including its ability to dissolve most metals (except noble metals and certain alloys that form a passivation layer), make it invaluable in numerous industrial applications. The acid itself is a monobasic acid, meaning it donates one proton per molecule in an aqueous solution, leading to its strong acidic nature. Industrially, it is primarily produced via the Ostwald process, involving the catalytic oxidation of ammonia. HNO3 is also a key component in the nitration of organic compounds, a fundamental reaction in the synthesis of many pharmaceuticals, dyes, and explosives. Its powerful oxidizing capabilities also render it effective in etching and cleaning processes across various sectors.
Applications
Nitric acid is extensively utilized in the production of ammonium nitrate for fertilizers, contributing significantly to agricultural productivity. It is a critical reagent in the manufacture of explosives such, and in the synthesis of organic nitrates and nitro compounds used in pharmaceuticals, plastics, and dyes. Furthermore, it serves as a powerful oxidizing agent in pickling and etching processes for metals, particularly in the steel and electronics industries, and is employed in the purification of noble metals. Other applications include its use in rocket propellants, as a laboratory reagent, and in various specialized chemical syntheses.
Storage & Handling
Store in a cool, well-ventilated area, away from incompatible materials, reducing agents, and combustible substances. Containers should be tightly sealed and made of corrosion-resistant materials. Handle with appropriate personal protective equipment, ensuring adequate ventilation to prevent inhalation of vapors. Avoid contact with skin, eyes, and clothing.
