7.6: Classifying Separation Techniques - Chemistry
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.

Separation Techniques Classification of Matter
A separation process or technique is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures. At least one of results of the separation is enriched in one or more of the source mixture’s constituents. In some cases, a separation may fully divide the mixture into pure constituents.

Methods for Separating Mixtures Chemistry for
Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material.Particle size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, viruses, and protozoans.
