Why sulphuric acid is known as the king of acids?

Concentrated sulphuric acid is called King of Acids because it is a strong acid and highly corrosive. It is more reactive than other acids. The major use of sulphuric acid is in the production of fertilisers, e.g., superphosphate of lime and ammonium sulphate. It is widely used in the manufacture of chemicals, e.g., in making hydrochloric acid, nitric acid, sulfate salts, synthetic detergents, dyes and pigments, explosives, and drugs.

Sulphuric acid is sometimes referred to as the “king of chemicals” because it is produced worldwide in such large quantities. The per capita use of sulphuric acid has been taken as one index of the technical development of a country. Annual production in the United States, which is the world’s leading producer, is well over 39 billion kg (86 billion pounds). It is the cheapest in bulk acid.
