Title: intermolecular bonds: dissolving salt and sugar
Post by: jennielynn_1980 on August 23, 2006, 12:23:30 PM

This is a really simple question but I am still having difficulty.  I have an educated guess but I don't know if I am right.

The question is: with the same type of agitation and at the same temperature, why would sugar dissovle if water much faster than does salt?

My educated guess:
Because the salt crystal has dipole forces with in the crystal and sugar has van der Waals forces that are weaker. 
OR
Because water would be able to form hydrogen bonds with the oxygen and hydrogen in the sugar.

look at kinetics, not thermodyanmics, to decide which solvation process is faster.
