Filtration Techniques

Filtration Techniques

1. Distillation

2. Crystalisation

   • CRYSTAlISATION is the act of

3. Filtration

   • In a funnel, you put a piece of filter paper and pour your liquid into it. The liuid will go straight through but any solkids will be left behind. This is called residue.
   • RESIDUE: solid left behind after filtration.

4. Chromatograhy

   • CHROMOTOGRAPHY: a way to separate soluble substances.
   • CHROMATOGRAM: the resulting evidence on paper.
   • SEPARATION: when one substance can move more than another in a liquid, this results in SEPARATION.

5. Fractional Distillation

   • FRACTION: molecules with a similar boiling point.
   • HEAVY: a substance with a high boiling point. LIGHT: a substance with a low boiling point.
   • HYDROCARBONS: long chain molecules found in crude oil.
   • FRACTIONAL DISTILLATION is a way fo separation the hydrocarbons in crude oil. Often used for business purposes.
     • Refinery gas
     • Naphtha
     • Diesel oil
     • Kerosene
     • Residue
     • Gasoline

6. Things I didn't understand

   • Hot water dissolves things quicker than cold water
   • COMPOUND: a two or more compounds chemically joined
     • SODIUM CHLORIDE IS A COMPOUND
   • ELEMENT: is a substance made up of only one kind of atom.
   • MIXTURE: two or more substances not chemically joined.
     • MILK IS A MIXTURE
