Sulfuric acid is a colorless, viscous liquid; it is hazardous and corrosive in nature. Sulfur is the major raw material used in the production of sulfuric acid, and around 90 percent of global sulfur production is used in the sulfuric acid production. The other methods of sulfuric acid production include production from smelter gas and iron pyrites.
