Homework Help: Organic CHEM

Posted by Adam on Monday, January 3, 2011 at 11:30pm.

What is the whole point of using solvent pairs for recrystallization(say a mix of ethanol and water) rather than just using one or the other?

-I know that you use solvent pairs when you solute won't dissolve in either pure water or pure ethanol, but then if the solute won't dissolve in either or, why does it dissolve when the solvent is a mix? That's what's really confusing.
Thanks :)
