Does anyone know what the 2 stage process is by which sulphur trioxide is converted safely into dilute sulphuric acid? Thank you:)

Sulphur Trioxide is dissolved in concentrated sulphuric acid to form OLEUM. OLEUM is diluted with measured amounts of water to form concentrated SULPHURIC ACID.

Are you doing the Edexcel C3 exam tomorrow, i am :) ?

Thank you! No - I'm doing WJEC C3 and am not looking forward to it!! But I got a's in C1 and 2 so if I do really badly hopefully I can still pass:)

Sulphur dioxide is mixed with concentrated sulphuric acid otherwise the reaction would be too exothermic. This produces oleum which is then mixed with water to produce sulphuric acid used in for example fertilisers! I'm doing wjec c3 and 2 tomorrow FML
