1. Separating Mixtures using Physical Properties How can you separate out many kinds of matter?

2. Separating Mixtures USING A MAGNET

3. Separating Mixtures USING A FILTER & FUNNEL This only works if the solid Is NOT dissolved by the solvent, and you have a suspension. After filtering, you have a precipitate.

4. Separating Mixtures USING EVAPORATION

5. Separating Mixtures USING DISTILATION

6. Separating Mixtures A separation funnel can be used if the two liquids will not mix. Often used when separating organic material (oil) and aqueous material (water). USING DENSITY Can be accelerated using sonication

7. Separating Mixtures USING CHROMOTOGRAPHY

8. Separating Mixtures (Combo) BY DISSOLVING & FILTRATION & EVAPORATION A mixture of salt and sand can be separated by dissolving the salt in water, then using filtration separate the sand from the aqueous salt layer. Then evaporate the water to obtain solid salt again.

9. Separating Mixtures (Combo) BY DISSOLVING & DENSITY A mixture of salt, sand, and blue plastic beads can be separated by dissolving the salt in water, then using density to separate into three layers.

10. Conservation of Mass MATTER CANNOT BE CREATED OR DESTROYED, ONLY CHANGE FORMS If you add vinegar (10 g) to milk (100g) and it thickens, how much matter do you have?

11. You will observe and analyze the separation of mixtures based on physical properties of matter. Separating Mixtures Lab

12. Separating Mixtures – How to fold a filter paper

13. Separating Mixtures – Lab Details ITEMS: GOGGLES, funnel, filter paper, filter cone, magnet, volumetric cylinder, water (from sinks), evaporating dish, and unknown substance mixture.

14. O Design step-by-step procedures to separate the mixture. Include a flow chart. O Describe how each substance was able to keep its own physical properties when it was mixed with another substance. (key words: density, magnetism, solubility) O How do you know that the mixture of substances is not a chemical combination? TURN IN ON THE ELMO BY THE END OF CLASS Separating Mixtures – Lab Write Up
