What is Nitric Acid/meaning/concept/elaboration

The chemical formula of this compound is HNO3. It is a liquid with a variable appearance, as it can be colorless or yellowish. It is a water-soluble compound and, although it is not combustible, it can accelerate the combustion of some materials. On the other hand, it is a very toxic inorganic compound that allows certain fabrics and metals to corrode . It is formed from the oxidation of ammonia. What is Nitric Acid?

Nitric acid can decompose and generate nitrogen oxides, which are especially toxic when there is an increase in temperature . The first historical references to this substance date back to the 13th century.

A very powerful oxidizing agent with many uses

Some explosives like nitroglycerin and TNT are made with nitric acid. It is also used to prepare organic nitrates that are used as nitrogen fertilizers for certain crops.

Some metals such as aluminum or stainless steel are superficially protected by this substance (the process carried out is known as passivation).

In the etching technique used in engraving, artists use plates or sheets that are treated with this acid. It is also used in the restoration of bronze and wooden objects. What is Nitric Acid?

It is also used in some industrial sectors, especially in the manufacture of electronic boards and in the metallurgical sector.

It can be used in the pharmaceutical industry, in the manufacture of dyes and inks, as well as in the preparation of ammonium nitrate. Plastics made with nitrocellulose also incorporate small amounts of nitric acid.

In ancient press it was used as an oxidizing agent in the preparation of lithographs.

A substance that must be handled with a strict safety protocol

Like other chemicals, this one has some health risks. As it is an irritant product, it can cause burns and ulcers when it comes into contact with the skin. Its inhalation is very harmful to the respiratory system and people who inhale its vapors in a habitual way are more at risk of suffering from laryngeal cancer. On the other hand, it erodes teeth and causes eye irritation.
