It's an aqueous solution of nitrogen, hydrogen and oxygen (HNO3). It is very corrosive (depends on the purity of the solution, but pH typically = 1) and therefore very toxic. So corrosive, in fact, that it can only be transported in specially made containers and even when well-sealed, these must be handled with great care.
Manufacture of HNO3 is typically under pressure, mixing nitrogen dioxide (NO2) with water and oxygen.
Industrial use of nitric acid includes:
Extraction of gold and platinum,
Metallurgy in general,
Manufacture of explosives,
As an oxidiser in rocket liquid fuel,
In fertilisers (this is the largest use, globally, by volume).
World production is about 60 million metric tonnes per year, most linked to the manufacture of artifical fertilisers.
HNO3 has many and varied other uses, in manufacturing, laboratory testings and to detect or measure amounts of other chemicals.
It becomes explosive when mixed with many substances, especially organic compounds (like turpentine).
Nitric acid is a component of acid rain (produced by atmospheric processes). So many people in the world have had skin exposure to it via rainfall, although very diluted.
