Nitric acid – HNO3 68% | South Korea

What is nitric acid (HNO₃)? Molecular structure of HNO₃

HNO Chemical₃, also known as acid nitric, is a colorless compound with the chemical formula Nitric acid. It is a strong acid that produces hydronium ions (H+) and nitrate anions (NO3-) when diluted in water.

Nitric acid is produced through the oxidation of nitrates in the air. It is used in the production of fertilizers, cleaning agents, and in the processing of dyes…

Physical and Chemical Properties of HNO₃

Physical properties

HNO₃ In its pure form, it is a colorless liquid that emits dense fumes in humid air; it is a toxic, corrosive acid that is highly flammable.

Density: 1522 kg/m³

Density: 1.51 g/cm³ and 1.41 g/cm³ [68% w/w]

Freezing point: -42°C

Boiling point: 83°C

Solubility in water: completely soluble

Acidity (pKa): -2

When exposed to light, even at room temperature, HNO₃ decomposes to form nitrogen dioxide according to the following reaction:

4HNO3 -> 2H2O + 4NO2 + O2

Chemical Properties of HNO₃

HNO₃ It is one of the strong acids that readily reacts with metals, salts, basic solutions, and nonmetals. It turns litmus paper red.

• HNO₃ reacts with metals to form salts, reduction products, and water:

Cu + 4HNO₃ (solid) -> Cu(NO₃)₂ + 2NO₂↑ + 2H₂O

• Reaction with a basic solution:

HNO₃ + NaOH ->  NaNO₃ + H₂O

• Reactions with inorganic salts form new salts and release gases:

CaCO₃ + 2HNO₃ --> Ca(NO₃)₂ + CO₂ + H₂O

• HNO₃ exhibits strong oxidizing properties when reacting with nonmetals:

C + 4HNO₃ -> CO₂↑ + 4NO₂↑ + 2H₂O

• Effects on Many Organic Compounds: Nitric acid can destroy many organic compounds, so it is extremely dangerous if it comes into contact with the human body.

Important Applications of Nitric Acid – HNO₃

• Fertilizer Production: HNO₃ is used to produce nitrate fertilizers. For example, ammonium nitrate (NH₄NO₃), an important fertilizer that provides nitrogen to crops.
• Dye production: Used in the production of dyes, particularly those with strong and fast colors.
• Production of gasoline: HNO₃ used to create a clean environment for other chemical reactions.
• Paper bleaching: Used to bleach paper, helping to remove reactive substances bound to cellulose fibers and making the paper bright white.
• Nano-technology manufacturing: Commonly used in the production and purification of nanomaterials, helping to remove impurities and improve product quality.
• Manufacture of water treatment chemicals: pH adjustment and water treatment in industrial processes, such as water clarification and Wastewater Treatment.
• Dye and paint production: Nitric acid—a nitrate catalyst—can act as an oxidizing agent in the glazing process and help create fade-resistant paint colors.
• Chemical analysis: Oxidizing agents used in chemical analysis methods, such as the manganate method or iron ion analysis.
• Rocket fuel production: As an oxidizer in rocket fuel, it supplies oxygen for the combustion process.
• Cosmetics and Detergent Manufacturing: Used in the cosmetics and detergent industries as bleaching agents and antibacterial agents.
