Filtration is the technique used to separate an
insoluble solid from the liquid in a liquid-solid
mixture

8. Application of filtration :
Water treatment

Distillation is the technique used to separate a pure
liquid from a solid-liquid or liquid-liquid mixture

Paper chromatography is the technique used to
separate small amounts of substances from mixtures
based on the different solubility of the components
in a particular solvent

13. Application of paper chromatography :
1. Identifyfoodcoloring
2. Identifying the dyes used in ink

14. Thetechnique used to separate a
mixturedepends on physical
properties of thesubstances

1. Water can be easily separated into elements (F)
2. Compounds can easily be separated into their parts
3. Our kidneys are the application of filtration in our body
4. Mixture can only be separated chemically
5. Substances in a mixture can be separated by using their different properties
6. The technique used to separate a mixture depends on the substance(s) to be obtained
from the mixture
7. One of the applications of paper chromatography is to test the purity of a substances
8. Evaporation is the technique used to separate dissolved solids from a solid-liquid
mixture
9. Distillation used to separate the pure liquid from a solid-solid mixture

16. CONCLUSION:
PRESENTATION
TITLE
16
1. Basedon the properties of mixture there are 5 separation techniques that can usedto separate the mixture
which is magnetic attraction (for magnetic materials only);filtration (for suspension);evaporation (basedon
different of vapor point of thing) and distillation (basedon the different of boiling point) (for liquid and
soluble solid/solution); paper chromatography(basedon the different of solubility)
2. Theapplication of magnetic attraction are to salvaging of iron and steel,to makesure the safety of food, to
find the things made bymetals element(iron, copper
,nickel, cobalt, steel, etc.), Filtration (makethe coffee,
water treatment),evaporation(to obtain the salt), distillation (to obtain water from potable water
,to
separate alcohol in water) and paper chromatography(identify the contents of a mixture, test the purity of
a substances)
