Sulphuric acid is an important chemical that is used to manufacture fertilizers like ammonium sulphate and potassium sulphate. It is also used to produce detergents, synthetic fibers, paint pigments, as an electrolyte in car batteries, and to prepare metal surfaces for electroplating. Sulphuric acid is manufactured via the contact process, which involves burning sulfur with air to produce sulfur dioxide, converting the sulfur dioxide to sulfur trioxide using a vanadium catalyst, and dissolving the sulfur trioxide in concentrated sulfuric acid to produce oleum and then dilute sulfuric acid. Sulfur dioxide released during the burning of fossil fuels can cause environmental pollution by dissolving in water to form acid
