The dissolution of SO3 in water is very exothermic. This leads to the formation of tiny droplets that are corrosive and can even attack the lead pipes used to cover the tower in the communication process.
In the preparation of H2SO4 by Contact Process, why is SO3 not absorbed directly in water to form H2SO4?
