Sulfur trioxide (SO3) dissolves in and reacts with water …

Sulfur trioxide (SO 3) dissolves in and reacts with water to form an aqueous solution of sulfuric acid (H 2 SO 4).The vapor in equilibrium with the solution contains both SO and H 2 O. If enough SO 3 is added, all of the water reacts and the solution becomes pure H2S04. If still more SO 3 is added, it dissolves to form a solution of SO 3 in H2SO 4, called oleum or fuming sulfuric acid.
