Nitric acid is an acid with a pungent odor, which in concentrated form is very corrosive.
The largest use of nitric acid is in the manufacture of ammonium nitrate, which in turn is used for the production of fertilizers and explosives.
Nitric acid (HNO3) is also used as a surface treatment agent in the steel industry, as a reagent in laboratories, as well as s cleaning agent in the food industry, where the nitric acid has E-number 507. The product also has applications in the pharmaceutical industry.
Nitric acid is a strong oxidant and if heated dissolves metals such as copper, silver and mercury. Mixtures of nitric acid and other acids create special properties. For example, nitric acid and hydrochloric acid forms what is known as aqua regia – one of very few substances that can dissolve gold and platinum.
