Answer:
The starting material for sulfuric acid manufacture is clean, dry sulfur dioxide (SO2) gas. In the contact process SO2 is oxidized to sulfur trioxide (SO3) at high temperature (about 450°C) in the presence of a vanadium catalyst. SO3 then is dissolved in concentrated sulfuric acid forming fuming sulfuric acid (oleum).
