Why in the manufacture of `H_2 SO_4` by contact process, sulphur trioxide is not directly dissolved in water ?

Text Solution

Verified by Experts

Sulphur trioxide `(SO_(3))` reacts the water to form `H_(2) SO_(4)` which is not easily condensed and excapes in the atmosphere. Hence, `SP_(3)` is absorbed in `conc. H_(2) SO_(4)` to form oleum, which is then diluted to form `H_(2) SO_(4)`.
`H_(2) SO_(4) + SO_(3) rarr H_(2) S_(2) O_(7)`
`H_(2) S_(2) O_(7) + H_(2) O rarr 2 H_(2) SO_(4)`.
