Two compound homogenous crystallization
« on: April 23, 2012, 08:36:47 AM »
Using the recrystallization purification method, can you take two compounds at a 1:2 ratio and dissolve them into a single solvent system under heat, then cool and expect homogenously mixed crystals to form?  If so why?

This is the question on my homework.  I can't find the material in my class notes, o chem manual or via google.  I'm probably not reading slowly enough or have "get it done fast"-itis which causes temporary blindness, heh.

Anyway a quick answer is good but I'd really love a push in the right direction.  While I do want the right answer for my homework, I wanna understand why I got the right answer too.

Thanks in advance!

Little hard to follow your terminology -- when you say "homogenously mixed crystals" do you mean a mixture of individual crystals as a homogenous mix of both types?  Or do you mean the two solids will co-crystallize?  Because that does sometimes happen.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
