Dr. Gorski’s IPS Class                       Name: ___________________________________ Attar of Roses: A Valentine’s Day Laboratory Investigation I. Purpose: In this experiment we will attempt to isolate the compounds that make up the fragrance of a rose.  Although this lab is partly for fun, we can use it to investigate some separation techniques (Chapter 5 material) and to  reinforce ideas, like solubility, that we have already studied. We will learn a couple of new techniques that we will  add to our laboratory skills repertoire. You will not be required to write a formal lab report for this experiment, however we will be discussing it and will be  responsible for any class information as well as any information contained in this handout.
