To separate into different component & different properties.
Separation:
It is a process to reveal the identities of the components in a mixture. However, it is hard to separate them, the properties, in which they have the similar properties.
Basic techniques
- Filtration: select components by particle size( undissolved solids and liquid)
Cystallization(Solid and Liquid)
The resultant which we want is a solid state formed by a chemical or physical change.
Distillation collects and condenses volatilized (vaporized) components. In other words, it is a process of boiling the liquid and vaporizing it and then condenses it back to purified liquid.
Chromatography is the purpose of separating complex components by flowing the mixture over a material that retains components more than others, so different components flow with different speeds on the material.
Paper Chromatography(PC)
A highly accurate component separation material. The paper is liquid soaked with the sheet or strip of paper. The components appear as separated spots on the paper chomatography after drying.
