Homework Help: CHEMISTRY

Posted by Del on Monday, October 22, 2007 at 9:16pm.

during column chromatography, if four fractions are done, how do we know what is in each beaker and why. I know that beakers 1 and 3 will contain the majority of the fractions being separated but what about beakers 2 and 4. How do we know that they are the residues of the fractions being collected
