Organic Chemistry Practical
Sublimation
- Sublimation is a method of separation that involves the transition of a substance from a solid to a gas state.
Methods Based on Physical Properties
- Five methods are used to separate mixtures based on their physical properties:
Filtration
- Filtration is a technique used to separate solids from liquids.
- It involves pouring a mixture onto a membrane (filter paper) that allows the passage of liquid (the filtrate) and results in the collection of the solid.
- Two types of filtration techniques are used in chemical separations:
Filtration Techniques
- Gravity filtration: used to separate an insoluble solid from a liquid when the solid is suspended throughout the liquid.
- Suction filtration: an alternative to gravity filtration.
Note
- A solid/liquid mixture is called a suspension.
