SO3 -> H2SO4 question
Sorry if this has been already covered. Obviously hydrating SO3 with water will yield H2SO4..but doing so directly I'd imagine is prolly pretty
dangerous since the reaction would without a doubt give off heat, and spitting oleum isn't exactly a good thing :p How would one go about hydrating
SO3 to obtain H2SO4 in a controlled, safe manner?

In industry, they add it to concentrated H2SO4 to make it even more concentrated.

More precisely, SO3 is added to cold concentrated H2SO4 with stirring, and a refrigeration loop is used to remove heat at a rate sufficient to keep
the product below the bp of SO3 so that redistillation does not occur.
See Merck for the heats of reaction. A little consideration of the stoichiometry, molecular weights and densitiies (and boiling points) will be
revealing.
