2. Mixture Separation
In chemistry and chemical engineering, a separation process is used to transform a
mixture of substances into two or more distinct products . The separated products could
differ in chemical properties or some physical property, such as size, or crystal
modification or other separation into different components
3. Filtering is based on size of the component of a mixture. The smaller particles will pass
through the filter and the bigger ones will remain be done separate solid substances of a
different size.
4. Distillation
Distillation is a method based on the difference of boiling point. This method can be
used to separate a mixture with a different boiling point. A mixture of water and gasolin can be
separated by distillation. The more various boiling points are, the easier the mixture is to be
separated.
The separating of a mixture by distillation can also be used to get pure water from, or
from contamineted one. The mixture between water and salt can also be separated by distillation.
Salt will stay on the round bottom glass and the water will come out trough the cooler
5. crystallizationcrystallization
Separation a mixture by crystallization is carried out to separate solid substanceSeparation a mixture by crystallization is carried out to separate solid substance
from its solvent. The solid substance in the saturated condition will form a crystal.from its solvent. The solid substance in the saturated condition will form a crystal.
6. sublimation
Separating a mixture by sublimation can be done if the sublimation is
contaminated with other substances. Sublimation is a process of changing solid substance
into gas or the other way around. Some sublimation substance are benzoic, iodine, and
caffeine.

7. Chromatoghrapy
Separating subtances by cromatoghrapy is based on the difference of the creeping speed of
substance in a certain medium. In our daily life, the separating process of substances by
chromatoghrapy can be observed in water infiltration on the wall. The infiltration will produce
stetches with certain distance.
