Extraction technique: It is the method used for separation and purification of organic compounds by pulling out of a substance from one solvent (usually water) to another. Solvent extraction technique depends on the differential solubility of a substance between 2 immiscible liquids. Apparatus used : Separatory funnel. Organic solvents are classified according to their density Requirements of solvent used in extraction:  Immiscible with water.  Inert (does not react with water or the substance being extracted).  Dissolves the substance better than water.  Volatile. Procedure https://youtu.be/6iB2U0RZLjc?si=Rtt8NFCnoqmtM72D Simple distillation: It is a process used for purification or separation of the components in a liquid mixture. The mixture is heated to evaporate the volatile liquid components, and the vapor is then condensed to a liquid. Principle of simple distillation: 1. separation of compounds based on the difference in the boiling points of two miscible liquids 2. the two liquids should boil without decomposition. Apparatus used: Simple distillation system. 1- Heat source (Hot plate) 2- Round bottomed flask 3- Still head / three- way adapter 4- Thermometer/Boiling point temperature 5- Condenser 6- water in 7- water out 8- Distillate/receiving flask 9- Vacuum/gas inlet 10- Still receiver https://youtu.be/0Zl5Oe543cg?si=nOp0Xticee4KoQpC
