प्रश्न
- Name the catalyst which helps in the conversion of sulphur dioxide to sulphur trioxide in step C.
- In the contact process for the manufacture of sulphuric acid, sulphur trioxide is not converted to sulphuric acid by reacting it with water. Instead a two-step procedure is used. Write the equations for the two steps involved in D.
- What type of substance will liberate sulphur dioxide from sodium sulphite in step E?
- Write the equation for the reaction by which sulphur dioxide is converted to sodium sulphite in step F.

उत्तर
- Platinum or Vanadium pentoxide
- \[\ce{SO3 + H2SO4 -> H2S2O7}\]
- \[\ce{H2S2O7 + H2O -> 2H2SO4}\]
- The substance that will liberate sulphur dioxide in step E is dilute sulphuric acid (H2SO4).
- \[\ce{SO2 + 2NaOH -> Na2SO3 + H2O}\]
- \[\ce{Na2O + SO2 -> Na2SO3}\]
