Sulfuric acid, often referred to as sulphuric acid in some regions, is a highly corrosive and strong mineral acid with the chemical formula H2SO4. It is a colorless, oily liquid that is odorless when pure but has a pungent smell when it comes into contact with certain substances. Sulfuric acid is one of the most essential and widely used industrial chemicals, with applications across various industries. It is a key component in the production of fertilizers, detergents, chemicals, and explosives. Sulfuric acid is also used in petroleum refining, metal processing, and the production of batteries, among other applications. It plays a crucial role in the synthesis of a wide range of chemical compounds.

Sulfuric acid is known for its strong acidic properties and its ability to react vigorously with many substances. It is essential in laboratory work, where it is used for various analytical and synthetic purposes. However, due to its highly corrosive nature, it must be handled with extreme caution and stored carefully.
