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 ...

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.
