Nitric Acid – Manufacturer, Supplier & Exporter | DPRJ Universal

What is the primary use of Nitric Acid?

The primary industrial use of Nitric Acid is in the manufacturing of ammonium nitrate fertilizers, explosives (like TNT and nitroglycerin), plastics, and dyes. It is also extensively used for metal refining, electroplating, and as a specialized nitric acid gold test solution.

What is the molecular weight and chemical formula of Nitric Acid?

The chemical formula for Nitric Acid is HNO₃, which is also its molecular formula and chemical symbol. The nitric acid molecular weight (or nitric acid molecular mass) is approximately 63.01 g/mol. Its official chemical name is hydrogen nitrate.

How is Nitric Acid prepared or synthesized industrially?

Industrial nitric acid preparation is achieved via the Ostwald process. This involves the catalytic oxidation of ammonia over a platinum-rhodium gauze to form nitric oxide, which is subsequently oxidized to nitrogen dioxide and absorbed in water to achieve the precise nitric acid concentration required.

What is the Nitric Acid structure and is it a strong acid?

The Nitric Acid structure consists of a central nitrogen atom covalently bonded to three oxygen atoms, one of which holds a hydrogen atom. Yes, Nitric Acid is classified as an exceptionally strong mineral acid that fully dissociates in an aqueous environment.

What is the nitric acid ka formula and dissociation behavior?

The nitric acid ka formula represents its acid dissociation constant expression in water: HNO₃ + H₂O -> H₃O⁺ + NO₃^-. Because it is a strong acid, its dissociation is virtually complete, and the nitric acid ph is highly acidic, falling below 1 in concentrated industrial solutions.

What are the key physical properties, such as boiling point and density?

Key physical properties of commercial-grade 68% concentrated Nitric Acid include a nitric acid boiling point of approximately 121 C and a nitric acid density of 1.41 g/mL at 20 C. The standard nitric acid colour appears as a clear, colorless to pale yellow liquid.

Does nitric acid turn red litmus blue or blue litmus red?

As a highly powerful strong mineral acid, Nitric Acid turns blue litmus paper red. The query 'nitric acid turns red litmus blue' represents a common chemical misconception; in reality, it will never turn red litmus blue, as it maintains or enhances the red acidic indication.

How does the nitric acid test for gold and its reaction with zinc work?

The nitric acid gold test relies on its strong oxidizing nature; it dissolves base metals but leaves gold unaffected, serving as an industry-standard purity test. Conversely, the reaction of nitric acid zinc is highly reactive, forming zinc nitrate along with water and nitrogen oxide gases.

Is Nitric Acid hazardous and what are the handling precautions?

Yes, concentrated Nitric Acid is highly corrosive, toxic, and causes severe skin burns and respiratory tract irritation. Industrial handling requires strict adherence to safety protocols, specialized personal protective equipment (PPE), and proper ventilation systems from a certified supplier.
