The Separation of the components of a Mixture

2. Safety
Put on Goggles
And Apron

3. Objectives Demonstrate Separation of a Mixture
Investigate Different Techniques for Separating Mixtures Using their Physical Properties

4. Mixtures
Any Material Made up to Two or More Substances Not Chemically Combined
Isolation of Pure Components Based on Their Physical Properties

5. Methods Five Methods of Separation Magnetic Separation
Use Magnet to Separate Ferromagnetic (Iron Fillings)
Extraction
Solvent Selectivity – Separating Soluble Solid from Insoluble
In this experiment We will use Five Methods of Separation

6. Methods Decantation Filtration
Separation of Liquid of Soluble Solid from Insoluble Solid (Pouring)
Filtration
Separation of Solid from Liquid via a Porous Material (Filter Paper, Charcoal, Sand, etc.)
Allows Liquid to Pass Through but not Solid

7. Methods
Evaporation
Removing Liquid by Heating until Dry Component Remains

8. Experiment Mixture Contains: Iron Fillings (Fe)
Copper (II) Sulfate (CuSO4)
Sand (SiO2)

9. Experiment Use Magnet to Remove Iron Fillings
Dissolve Copper Sulfate with Water to Extract
Filter Sand/Copper Sulfate Mixture
Evaporate Water to Recover Dry Copper Sulfate and Sand

10. Calculations

11. Weight of Iron Fillings
Weight of Watch Glass and Mixture – Weight of Watch Glass and Mixture After Removing Iron Fillings

12. Weight of Copper Sulfate
Weight of Beaker 1 and Copper Sulfate – Weight of Beaker 1

13. Weight of Sand
Weight of Beaker 2 and Sand – Weight of Beaker 2

14. Weight of Recovered Solids
Weight of Iron Fillings + Copper Sulfate + Sand

15. Percent Yield Percentage of Recovered Solid
Weight of Recovered Solid – Weight of Mixture X 100

16. Percentage of Iron
Weight of Iron Fillings – Weight of Mixture X 100

17. Percentage of Copper Sulfate
Weight of Copper Sulfate ÷ Weight of Mixture X 100

18. Percentage of Sand
Weight of Sand ÷ Weight of Mixture X 100
