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.

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.
