Sulfuric acid • Sulfuric acid (H2SO4) is a strong, heavy acid with a • density of 1.84 g/cc and a marked tendency to • absorb moisture from the air, generating much heat. • Concentrated sulfuric acid (93-98%) is used in the • manufacture of fertilizers, explosives, dyes, and • petroleum products. Sulfuric acid is formed during the • Contact Process. The Contact Process forms sulfur • trioxide (SO3) gas from sulfur dioxide (SO2) and oxygen • in a catalyst tower, and sulfuric acid is formed • when water is added. A mixture of H2SO4 and free • SO3 is equivalent to a sulfuric acid concentration of • over 100 percent. This mixture is called fuming sulfuric • acid or oleum. • Checkout for more information: https://chemistry.tutorvista.com/inor... • • Follow us at: •   / tutorvista   •   / tutorvista
