Is SO3 Actually Soluble in Water?

AI Thread Summary
Sulfur trioxide (SO3) is indeed soluble in water, reacting exothermically to form sulfuric acid (H2SO4). The discussion highlights that while SO3 can dissolve in water, the reaction occurs almost instantaneously, making it difficult to observe a stable solution of SO3 in water. The conversation also touches on the dangers associated with handling sulfuric acid, particularly when heated, which can release SO3 gas. Overall, the key takeaway is that while SO3 is soluble in water, its rapid reaction with water complicates the observation of a true aqueous solution.

Is SO3 soluble in water??

i know it reacts very exothermically with water to form water soluble products (H2SO4). But is SO3 itself soluble in water?
 
Chemistry news on Phys.org
of course, which is energetically favourable.
 
Think of it this way: If you heat (but do not try this because it can be extremely dangerous) sulfuric acid enough, it will push sulfur trioxide as a gas out of solution. Think of sulfur trioxide as the anhydrous form of sulfuric acid. Yes, sulfur trioxide is soluble in water.

It probably is, but, have you really ever seen a water solution of SO3?
 
noo... i don't think they have those in high school labs!

Don't know what you intended exactly, but I intended: since SO3 reacts with water instantaneously, how can we see a water solution of it?
 
awwww ok... lol... i didn't think of it as sarcastic... i thought there really were solutions of SO3 dissolved in water.

haha, thnks anyway
