Introduction: What is Fuming Nitric Acid?

Fuming nitric acid is a powerful oxidizing agent, used to produce nitric oxide. It is an oxidizer that has been used in the production of dyes and explosives. The fuming nitric acid is also known as “dilute nitric acid” and “highly concentrated nitric acid”. It is also used as an etchant in Microfabrication processes such as photolithography. Fuming nitric acid can be mixed with Hydrochloric acid to create a powerful cleaning agent called Hydrofluoric acid.
The use of fuming nitric acid in the production of explosives was common before World War II, but it has since been replaced by other agents that are less toxic and more stable than fuming nitric acid. In the laboratory, Fuming Nitric Acid can be used to make other chemicals such as Chlorates, perchlorates and nitrates

What is Fuming Nitric Acid Used For?

Fuming nitric acid was first created by the French chemist Louis Claude Cadet in 1811. He had been experimenting with nitric acid for a long time when he accidentally discovered that adding copper caused fumes to form. Cadet found that these fumes were more powerful than the liquid and so he named them ‘fuming’.
Fuming nitric acid is a kind of toxic and corrosive acid. It is used to manufacture dyes, explosives, and medicines. This acid is also used in the production of fertilizers, explosives, dyes, high explosives, pharmaceuticals, and many other products.

How to Prepare Fuming Nitric

This section discusses how to prepare fuming nitric acid. The preparation of nitric acid is an exothermic reaction that can be dangerous if not done correctly. It is important to follow the instructions carefully and to use the correct equipment.
The following is a set of instructions on how to prepare fuming nitric acid.

  • Add 100 g of potassium nitrate to a flask with 250 ml of water and boil it for five minutes.
  • Add 10 g of nitric acid and boil the mixture for another five minutes.
  • Allow the mixture to cool down and then pour it into a beaker with 200 ml of cold water and stir it until the solution becomes clear.
  • Pour this solution into a 250 ml volumetric flask, add 50 ml of Hydrochloric acid, and dilute it to the mark with distilled water in order to obtain 100 ml of fuming nitric acid solution
