प्रश्न
Name the oxide of sulphur which reacts water to give sulphuric acid.
In the contact process, the direct reaction between oxide of sulphur and water is avoided. In this process what does the oxide of sulphur react with instead of water, and what is the name of the product?
उत्तर
Oxide of sulphur which reacts with water to give sulphuric acid is sulphur dioxide.
SO2 + 2H2O + O2 → 2H2SO4
In the contact process Oxide of sulphur react with sulphuric acid to form Oleum.
SO3 + H2SO4 → H2S2O7
