Contact Process

Sulphuric Acid

Sulfuric acid is produced from sulfur, oxygen and water by contact process.  1. Contact Process: ⇒ Sulfur is burned to produce sulfur dioxide. S (s) + O2 (g) → SO2 (g) ⇒ This is then oxidized to sulfur trioxide using oxygen in the presence of a vanadium oxide catalyst. This reaction is reversible and the formation of the sulfur trioxide is exothermic. So Read more about Sulphuric Acid[…]
