Answer 1

Answer:

Sulfuric acid is sometimes referred to as the “king of chemicals” because it is produced worldwide in such large quantities. In fact, per capita use of sulfuric 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 bulk acid.
