Methods of Separation of Mixtures with Examples
We use different methods of separation to get individual components from the mixture. Separating or extracting different components from a mixture using some physical methods is called separation of mixtures. We often use it to remove unwanted or harmful components and to separate the individual components from the mixtures.

7.6: Classifying Separation Techniques
Distillation, sublimation, and recrystallization use a change in physical state to effect a separation. Chemical reactivity also is a useful tool for separating analytes and interferents. For example, we can separate SiO 2 from a sample by reacting it with HF to form SiF 4. Because SiF 4 is volatile, it is easy to remove by evaporation. If we ...
