प्रश्न
Sulphuric acid is manufactured by the contact process.
Name the chemical used to dissolve \[\ce{SO3}\] and also name the product formed. Give all the main reactions to this process.
उत्तर
The chemical used to dissolve \[\ce{SO3}\] is concentrated sulphuric acid. The product formed is the oleum, or pyrosulphuric acid.
\[\ce{SO3 + H2SO4 -> H2S2O7}\]
Main reactions of the process are
\[\ce{S + O2 -> SO2}\]
\[\ce{4FeS2 + 11O2 -> 2Fe2O3 + 8SO2}\]
\[\ce{2SO2 + O2 <=>[_2O5][450^\circ C] 2SO3}\]
\[\ce{SO3 + H2SO4 -> H2S2O7}\]
\[\ce{H2S2O7 + H2O -> 2H2SO4}\]
