Sulfuric acid (sulphuric acid in British English) is a strong (strong acid) mineral acid with the molecular formula chemH (hydrogen)2chemlink=sulfateSO4. It is soluble in water at all concentrations. Sulfuric acid has many applications, and is one of the top products of the chemical industry. World production in 2001 was 165 million tonnes, with an approximate value of US$8 billion. Principal uses include lead-acid batteries (lead-acid battery) for cars and other vehicles, ore processing, fertilizer manufacturing, oil refining (Oil refinery), wastewater processing, and chemical synthesis.
