SUMMARY

Sulfur trioxide (SO3) is indeed soluble in water, reacting exothermically to form sulfuric acid (H2SO4). The discussion clarifies that while SO3 can dissolve in water, it does so instantaneously, making it difficult to observe a stable solution in laboratory settings. Participants emphasize the energetic favorability of this reaction and caution against heating sulfuric acid due to the dangerous release of SO3 gas. Overall, SO3 is recognized as the anhydrous form of sulfuric acid, reinforcing its solubility in water.

PREREQUISITES
  • Understanding of chemical reactions and solubility principles
  • Knowledge of sulfuric acid (H2SO4) properties
  • Familiarity with exothermic reactions
  • Basic chemistry laboratory safety protocols
NEXT STEPS
  • Research the properties and reactions of sulfur trioxide (SO3)
  • Study the formation and characteristics of sulfuric acid (H2SO4)
  • Learn about exothermic reactions and their implications in chemistry
  • Explore laboratory safety measures when handling reactive chemicals
USEFUL FOR

Chemistry students, laboratory technicians, and professionals involved in chemical manufacturing or research will benefit from this discussion on the solubility of sulfur trioxide in water.

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
