1. Separating a Synthetic Pain Relief Mixture

2. What is the mass percent of pain reliever in your mixture?

3. Based on immiscible (liquid- liquid) substances
Methods of Separation
Filtration, evaporation, crystallization, distillation, extraction
What is extraction?
Based on immiscible (liquid- liquid) substances
Use about 50 mL ethyl acetate and let sit for 5-7 minutes.

4. How to use separatory funnel
Close stop cock to ensure liquid will not spill.
Hold stopper when inverting the funnel to avoid having the stopper fall out when funnel is upside down.
Open stopcock to VENT excess pressure.
Repeat the shaking/venting process to ensure equilibrium distribution of the organic solute between the desired layers.
