This lab exercise gives students a problem scenario (a mixture of 4 solids) and asks them to determine a way to separate them from each other utilizing experimentation, previous knowledge, and discussion.  Students are expected to write a standard operating procedure detailing the method they determine for the separation at the end of the lab.  A modified version of this lab was originally performed in an accelerated summer class on chemistry given to 7^th, 8^th, and 9^th graders that were on a track for early entrance into college.  The lab was done over the c

This is the procedure for a Fe(III) catalyzed synthesis of aspirin, an alternative to the traditionally sulfuric acid catalyzed synthesis of aspirin.  The prep compares and contrasts the Bronsted acid catalyzed esterification reaction with a Lewis acid iron (III) catalyzed pathway.  This can be used in different courses at different levels, but is it written for a general/intro level chemistry course.
