physical separation

physical separation

1. filteration

   • Pour solution through filter; undissolved particles will not get through

2. distillation

   • liquids with different boiling point will be separated: the one with a lower boiling point will evaporate, and the other one will be left behind

3. chromatography

   • separate solids which are soluble in the same solvent, but have a different solubility. ink will be at different levels on the paper, which will identify them.

4. evaporation

   • used to separate a solid from the liquid its dissolved in. the liquid will evaporate because of the heat, and the solid will be left behind.

5. separating tap

   • immiscible liquids: put into tube, and let out by tap until one runs out

6. centrifuing

   • put into tubes, and spun so solider sinks to the bottoms and you are left with the liquid

7. fractional distillation

   • glass beads inside cylinder, liquid with lower boiling point will evaporate, you will be left with one of the liquids.
