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.

Nitric Acid Manufacturer: Shijiazhuang Xinlongwei Chemical Co., Ltd.

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.
