If aspirin is placed into an aqueous solution of a low pH (1.5) it is in its unionized form.What intermolecular forces would exist between the aspirin and the water at this low pH?
Also at a high pH (8) the aspirin is in its ionized form. What intermolecular forces would exist between the water and the aspirin at this point?
Thanks for any help!

Well, at low pH, I don't think any intermolecular bonds would exist except maybe a few weak van der waals forces or london forces (whatever they're called).
At higher pH's the Aspirin, because it is a weak acid will dissolve because there are OH- ions floating around in solution at a higher pH. So Aspirin is able to donate it's H+ ion and that's how it's soluble. That's an ionic bond I think! But I haven't done this in so long. Hope that helps a little?
