Separating Techniques

Separating Techniques

1. Filtration

   • Separates insoluble solid from a liquid/solution
   • Residue is the insoluble solid
   • Pour the solution and insoluble solid into the funnel with the filter paper
     • The filtrate will pass through but the residue won't

2. Fractional Distillation

   • Separating liquids with different boiling points
   • Take away potentially troublesome mixtures
   • Then cool the gases
   • And then heat them, separating the fractions out

3. Seperating Funnel

   • Separating immiscible liquids
   • Less dense on top
   • Open the tap at the bottom
   • Close the tap when it is seperated

4. Simple Distillation

   • Separates solvent from a soluble solid
   • Heat the solution
   • The solvent will evaporate and condense back in the cool condenser
   • This separates the mixtures

5. Chromatography

   • Separates solutes based on how soluble they are
   • Draw line at the bottom with a dot of the solute
   • Put the paper in the solvent below
   • The more soluble ones will rise higher
