Need Nitric Acid? Buy From Leading Chemical Manufacturers

Nitric acid (HNO3) is a strong and highly corrosive mineral acid with widespread uses across various industries. 

Chemical characteristics:

  • Acidity: Nitric acid is a powerful acid. It releases hydrogen ions (H+) when dissolved in water. It is one of the six strong mineral acids and is highly corrosive
  • Chemical formula: Its chemical formula is HNO3, consisting of one hydrogen atom (H), one nitrogen atom (N), and three oxygen atoms (O)
  • Colour and appearance: Pure nitric acid is a colourless liquid, but may appear yellowish due to the presence of nitrogen dioxide (NO2) fumes
  • Odour: Nitric acid emits pungent, choking fumes and has a distinct odour that is sharp and biting
  • Concentration: Nitric acid is commercially available in various concentrations, including highly concentrated forms such as fuming nitric acid

Nitric acid is indispensable in industries like agriculture, mining, and chemical manufacturing, where it is essential for the production of fertilisers, explosives, and a wide range of chemical products. In the pharmaceutical and laboratory sectors, it plays a crucial role in chemical analysis and research.

This acid is also used in metallurgy, where it helps maintain the quality of metal products by removing impurities and surface contaminants. Its application in rocket propellants and explosives makes nitric acid significant in defence and aerospace industries.

Applications of Nitric Acid

Nitric acid is known for its widespread uses across multiple industries. Most notably, it plays a pivotal role in the production of ammonium nitrate (NH4NO3), a crucial nitrogen-based fertiliser. In this context, nitric acid serves as the primary source of nitrate ions (NO3-). This is done by neutralising nitric acid with ammonia (NH3) to form NH4NO3.

The concentration of nitric acid used in this production process can be adjusted to control the composition of the resulting ammonium nitrate fertiliser. This allows for the production of products with specific nitrogen content to meet agricultural needs.

Nitric acid also plays an important role in metal etching and processing. As a constituent of nital solution, it is widely used as an etchant in metalworking and metallurgy to react with and dissolve certain metals. This reveals their microstructure and facilitates various metalworking processes.

Here is an overview of some of the other popular uses of nitric acid:

  • Chemical manufacturing: Nitric acid is a crucial raw material in the production of various chemicals, including explosives like nitroglycerin.
  • Laboratory and analytical chemistry: Nitric acid is commonly used in laboratories for various analytical techniques, including acid digestion of samples, preparation of reagents, and as a cleaning agent for glassware.
  • Pharmaceuticals: Nitric acid is used in the synthesis of certain pharmaceuticals and in the production of nitroglycerin, a medication used for heart conditions.
  • Water treatment: In water treatment, nitric acid can be used to adjust pH levels and remove heavy metals from wastewater.
  • Explosives and munitions: Nitric acid is a key ingredient in the production of explosives used in military and mining applications.
  • Rocket propellants: Nitric acid is used as a component in rocket propellants and fuels. For example, red fuming nitric acid (RFNA) is a common rocket propellant composed of 84% nitric acid, 13% dinitrogen tetroxide and 1–2% water.

Nitric Acid: Storage Recommendations

In concentrated solutions, nitric acid is strongly acidic, highly corrosive and emits hazardous fumes. Always refer to the product’s MSDS for information on how to handle and store this chemical safely. 

Proper storage of nitric acid is essential not only to ensure safety, but also to maintain the product’s effectiveness. Here are important storage recommendations for nitric acid:

  • Store containers made of materials that can resist its corrosive properties. Suitable materials include glass, high-density polyethylene (HDPE), or fluorinated plastics
  • Ensure that the storage container is tightly sealed to prevent contamination, the evaporation of nitric acid fumes and the escape of hazardous vapours
  • Store in a well-ventilated area with good air circulation. Keep away from direct sunlight, heat sources, and open flames, since nitric acid is flammable and reactive
  • Store nitric acid separately from incompatible materials that could react with it, including strong bases, organic materials, and reducing agents
  • Consider using secondary containment measures, such as trays or bunds, to contain spills and leaks and prevent accidental contamination of the storage area
