Separating Mixtures WS (ONLINE)

2. Aim # 3: How can we separate a mixture?

3. How many phases of matter do you observe?
CuSO4(S)
H2O

4. How many phases of matter do you observe?
Liquid

5. Is a homogeneous or heterogeneous mixture? Why?
Do you know the formula for
Copper II sulfate?
CuSO4(S)

6. How can you separate copper (II) sulfate from the solution?

7. 1. Evaporation
To separate a non-volatile soluble salt from a liquid or recover the soluble solid solute from the solution.
Evaporation of a solution

8. What method can you use to separate muddy water ?

9. 2. Sedimentation or Decantation
To separate the mixture of coarse particles of a solid from a liquid.

10. Can you use other method to separate muddy water?

11. 3. Filtration
Filtration is a process that separates the solid and liquid parts of a mixture.
Example: sand and water.

12. 3. BEAKER 1. STIRRING ROD 4. FILTER 2. RESIDUE 5. FUNNEL 6. BEAKER
7. FILTRATE

13. FILTRATION
Sand : SiO2

14. CuSO4 (aq)+ sand Can we separate this sample by filtration?
Sand : yes
CuSO4: no
Why? They formed ions and they are very small and passed trough the filter

15. FILTRATION

24. Is wine a mixture?
How can you separate wine?

25. DISTILLATION

26. Crude Oil or Petroleum

27. FRACTIONAL DISTILLATION

29. 4. DISTILLATION
Distillation is a process in which a mixture of liquids can be separated by its boiling points.

31. How can we separate red blood cells and plasma from blood?

32. CENTRIFUGE

33. 5. Centrifuge
A centrifuge separates the more dense and less dense particles in the mixture.

34. What are the colors that exist in the spinach?

35. 6. CHROMATOGRAPHY
Chromatography is a way to separate different molecules in a mixture.
Example: INK and alcohol.
