1. What do these have in common? Crude Oil Red Wine Salt Water Toilet Waste

2. What does this group have in common? Coffee Gas Drinking Water Gold

3. What connects the two groups? VS ImpurePure  Separation of Mixtures  Separation of Mixtures

4. Filtration By passing the mixture through a screen, particles larger than the holes in the screen do not make it through Is the best at separating large particles from a liquid mixture Does not separate solutions Cheap E.g. Coffee

5. Sedimentation By giving a mixture time to sit, you allow heavier particles to settle at the bottom You can then skim off the pure liquid from the top or pour it out Good for separating large particles from liquid mixtures where you don’t need to get 100% of them. Cheap E.g. Toilet Wastewater.

6. Decantation The process of pouring a mixture from one container to another This will leave larger particles behind Cheap Not 100% E.g. Red Wine

7. Distillation Evaporate the liquid part of the mixture and let it condense somewhere else Because it uses boiling point, it can be 100% Works for solutions too More expensive since it needs heat E.g. Making salt water into drinking water

8. Fractured Distillation Same idea as distillation but better for getting more than one substance out of a mixture Each different substance has its own boiling point Uses a column with a range of temperatures Heavier substances condense on the hotter levels. E.g. Turning crude oil into gas
