Separating Mixtures

Separating Mixtures

1. A mixture contains two or more substances that have not reacted chemically with each other

2. A mixture is made of little bits of each substance, that are put togther

3. Salty water evaporates then flows down the tube and then the cold water condenses it

   • removing salty water from water

4. Group 1

   • Evaporation-Turning from a liquid to a gas
   • Distillation-Evaporation followed by condensation
   • Condensation-Turning from a gas to a liquid

5. Group 2

   • Chromotography-A way to separate soluble substances
   • Chromatogram-The resulting evidence on paper
   • Separation-When one substance can move more than another liquid

6. Group 3

   • Fractional-A type of distillation used to sperate crude oil
   • Boiling Point-The temperature at which a substance turns from a liquid to a gas
   • Fraction-Molecules with similar boiling points
   • Heavy-Substances with a high boiling point
   • Light-Substances with a low boiling point
   • Hydrocarbons-Long chain Molecules found in crude oil
