Final answer:
One of the major uses of sulfuric acid is the production of phosphoric acid, which is extensively used in the manufacture of fertilizers and in various chemical industrial applications.
Step-by-step explanation:
One of the major uses of sulfuric acid is the production of phosphoric acid. This is a pivotal substance used in a variety of industries. The process involves the reaction of sulfuric acid with phosphate rock, resulting in phosphoric acid, which is then used to produce fertilizers, especially superphosphates. In addition, about 20% of sulfuric acid is deployed in the chemical industry for the production of various chemicals, including detergents, synthetic resins, dyestuffs, and pharmaceuticals. It also serves roles in processes such as oil well acidizing, water treatment, and aluminum reduction.
Sulfuric acid is not only crucial to these applications but also plays a significant part in the production of batteries, acting as an electrolyte in lead-acid batteries. With its molecular formula H₂SO₄, sulfuric acid's importance as a central substance in the chemical industry cannot be understated. As such, the continued high global production of sulfuric acid reflects its crucial role in various industrial processes.
