2. 1. Filtration
- is a technique in which an insoluble solid is
separated from a liquid.
- it uses a filter like mesh cloth or a filter
paper to separate solid components from a
liquid.

3. Filtration

4. 2. Evaporation
- Is a technique used in separating a soluble
solid from a liquid.
- This method is used also by people who
produced salt by evaporating sea water
under the sun.

5. Evaporation

6. 3. Distillation
- Is a process of separating liquids from a
solution.
- The separation technique is based on the
differences of the boiling point of the
substances in the mixture.
- It is where a mixture is heated.

7. 3. Distillation
- The substance with the lowest boiling point
boils into vapor and condenses to liquid. It
is collected as distilled water.
- Is used in producing pure water, distilled
water or ethanol.
- Most homogeneous solutions can be
separated by distillation.

8. Distillation

9. 4. Decantation
- Is a technique used in separating a less-
dense substance from a denser one.
- Mixture is left undisturbed.
- When the components are separated, the
less-dense substance could be removed by
scooping using a spoon or it can be
removed by slowly pouring out

10. 4. Decantation
the less-dense substance.
- It is used in removing oil or gasoline from an
oil spill
Example: oil in water and fats that float in
sinigang could be removed by decantation or
scooping.

11. Decantation

12. 5. Chromatography
- It is used in hospitals to detect the level of
alcohol in the bloodstream.
- It is also used in environmental agencies to
detect the level of pollutants in the water
supply.

13. 5. Chromatography
- A technique that separates the components of
mixtures that are based on the ability of each
component to be drawn across the surface of
another material.
- It is good in separating dissolved substances
that have different colors, such as ink and plant
dyes.

14. Chromatography

15. 6. Physical Manipulation
- Is a technique used in separating the solid
components of a heterogeneous mixture.
- The components of the mixture should be big
enough to be seen and picked up by hands or
forceps.

16. Physical Manipulation

17. 7. Use of Magnets
- It is good in separating metals from non-metals.
- Used of magnets is also utilized in industries,
especially in junkyards. They remove metal
scraps from other materials using a big magnet.

18. Use of Magnet

19. 8. Sieving
- Involves using a strainer or a big screen to
separate the components of solid mixtures. The
strainer allows only the fine particles through it
and prevents the larger ones.
- Mixtures with big and fine components can
be separated by sieving.

20. Sieving

21. 9. Winnowing
- The mixture is allowed to fall from a height.
- The lighter components get separated from the
heavier ones because of the wind or air blows.
- This method is used to separate lighter husk
from heavier grains like wheat.
