Molecular Formula: HNO3 

UN No.: 2031

HS No.:2808000090

CAS No.:   7697-37-2

EINECS No.:      231-714-2

Hazard Class:  8+5.1 

Purity:  60% 65% 68% 

Appearance: Colorless transparent solution


Physical and Chemical Properties:

Nitric Acid (HNO3) is a clear, colorless to slightly yellow inorganic acid. It is a strong monobasic acid and a powerful oxidizing agent.

Nitric acid is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercial available nitric acid has a concentration of 68% in water.

By far the principal use of nitric acid (80%) is in the manufacture of fertilizers. Of this 96% is used to make ammonium nitrate and calcium ammonium nitrate. A relatively small amount of ammonium nitrate is used to make explosives.

Some nitric acid is used to make intermediates in the polymer industry, notably in the manufacture of hexanedioic acid (adipic acid) to make polyamides and TDI (toluene diisocyanate or methylbenzene diisocyanate) and dinitrobenzene two of a range of reagents used to make polyurethanes.  Nitrobenzene is used to make aniline which is a key reagent for making dyes.

Nitric Acid (HNO3) is a clear, colorless to slightly yellow inorganic acid. It is a strong monobasic acid and a powerful oxidizing agent. Nitric acid with water forms a constant boiling mixture (azeotrope) which having 68 % HNO3 and boils at 121 °C.

Nitric acid (HNO3) is an extremely important chemical used in the manufacture of fertilisers and explosives. It is made from ammonia by the Ostwald Process (developed in 1902 by the German chemist Wilhelm Ostwald, who got the Nobel prize in 1909). This process reacts together O2 and NH3 at 850°C and 5 atmospheres pressure, with the help of Platinum and Rhodium catalysts, to make NO. This is then oxidised to NO2, which is then dissolved in water to make HNO3. The Ostwald process was discovered just in time for the First World War, and it contributed greatly to the extended length of that war. This is because previously Germany had no nitrate deposits of its own from which to make the nitric acid that was essential for the production of the explosives used in artillery shells, such as TNT and nitroglycerin. In fact, most of the nitrates were only available from guano, which is the droppings of fish-eating sea birds, and is found in large quantities on the islands off the coast of Peru. When hostilities began, the shipping routes to Germany across the Atlantic were blocked, and so the Ostwald process gave Germany the ability to carry on the war far longer than it would otherwise have been able.


Do not store near combustible materials. Do not store in direct sunlight. Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from metals. Store away from alkalies. Separate from organic materials. Inspect periodically for damage or evidence of leaks or corrosion.
