उत्तर
The chemical used to dissolve SO3 is concentrated sulphuric acid. The product formed is the oleum or pyrosulphuric acid.
\[\ce{SO3 + H2SO4 -> H2S2O7}\]
Main reactions of the process are:
\[\ce{S + O2 -> SO2}\]
\[\ce{4FeS2 + 11O2 -> 2Fe2O3 + 8SO2}\]
\[\ce{2SO2 + O2 <=>[V2O5][450^\circ C] 2SO3}\]
\[\ce{SO3 + H2SO4 -> H2S2O7}\]
\[\ce{H2S2O7 + H2O -> 2H2SO4}\]
