ulfuric acid (H2SO4) is a strong, white, corrosive chemical compound that is used in a variety of industries. It is primarily produced from the oxidation of sulfur dioxide (SO2) in the presence of water and oxygen. Sulfuric acid is used in the production of detergents, fertilizers, dyes, and other chemicals, as well as in the manufacturing of battery acid. It is also used in the production of the herbicide glyphosate. Sulfuric acid is highly acidic and can cause severe burns if it comes into contact with skin or eyes.
