A colorless liquid with a molecular weight of 63.02 and a specific gravity of 1.502, nitric acid exhibits a light yellow tint and peculiar odor, fuming when exposed to air. It's a potent acid and oxidizer, reacting aggressively with bases, decomposing under light, and corroding most metals except gold and platinum. Iron, chromium, and aluminum exhibit passivity against it. When heated, it decomposes, emitting toxic fumes and posing risks of violent reactions with flammable or reducing substances and organic compounds.
Industrial applications
As a highly reactive compound, nitric acid has extensive industrial applications. It is best known for assisting nitrate-containing fertilizer fabrication, such as calcium nitrate and ammonium nitrate. However, it also has numerous other uses. These include
Purification of precious metals, such as gold, silver, and platinum
01
Formulating dyes, performance, and pharmaceuticals
02
Creating explosives, including TNT, ammonal, and nitroglycerin
03
Manufacturing Nylon and other synthetic fibers
04
Making fluids that dissolve the noble elements (neon, argon, etc.)
05
Laboratory uses
Nitric acid also has extensive uses in the laboratory setting. Technicians can use it as a catalyst, oxidizing agent, reagent, and more. Here are some standard use cases
Catalyzing reactions without consuming or significantly altering the desired products
Precipitating various inorganic compounds from solutions, such as iron hydroxide
Becoming a reagent in various spectroscopy techniques to identify the presence of compounds or properties of organic substrates
Oxidizing alcohols, ketones, and aldehydes
Introducing a nitro-group (-NO2) to organic molecules
Cleaning metal and glassware surfaces
Safety precautions when handling nitric acid
If you handle nitric acid, take the following safety precautions
Don’t let it touch your skin. Contact will cause severe chemical burns. (If you get in on bare skin, wash it off with plenty of water).
Store it correctly. Always label nitric acid according to regulations and keep it away from sunlight or heat. Ensure only authorized personnel can access it.
Avoid breathing nitric acid vapors. Exposure can cause sputtering, coughing, and irritation to the respiratory tract.
Don’t get it in your eyes. If you do, wash it out with clean water for fifteen minutes. Failing to remove all the acid could lead to permanent eyesight damage.
Always wear personal protective equipment (PPE). Use chemical-resistant gloves and masks to protect your skin and olfactory senses.
Ensure proper ventilation. Nitric acid can build up to dangerous levels in stuffy rooms. If you don’t have good ventilation, use a fume hood.
