Nitric acid ( HNO3cap H cap N cap O sub 3 ) is a highly corrosive mineral acid used extensively in industrial, laboratory, and DIY applications. Because it is a strong oxidizing agent and a precursor to explosives, purchasing it involves specific safety and regulatory considerations. Common Uses

Nitric acid should be stored in its original container inside a secondary containment tray. It is vital to keep it isolated from organic solvents, alcohols, or flammable materials, as contact can lead to spontaneous combustion or violent reactions.

Most concentrated nitric acid is sold at approximately 68-70%. Fuming nitric acid (over 86%) is significantly more hazardous and often requires specific permits or professional credentials to acquire.

In many jurisdictions, suppliers require a business license or an "End Use Statement" to verify that the chemical is being used for legitimate industrial, agricultural, or research purposes. Safety and Storage

Essential for passivation (removing surface contaminants) of stainless steel. Agriculture: A key ingredient in high-quality fertilizers.

Work must be conducted in a certified fume hood or a highly ventilated area to prevent the inhalation of toxic nitrogen dioxide fumes.

For bulk quantities (drums or totes), large-scale distributors like Brenntag or Univar are standard.
