43 Exp 6: Liquid-Liquid Extraction Week 2 Objective The purpose of this experiment is to apply what you've leaned about liquid/liquid separations to the analysis of a simulated mixture of Methylenedioxypyrovalerone (MDPV, aka 'Bath Salts') and an unknown cutting agent. Your goal is to separate the cutting agent from the drug. You will also need to test the compound purities. Acid/base extraction is one of the more difficult principles in organic chemistry to understand. The most straight-forward approach to understanding...
