Pure substances are those in which all the molecules are of the same nature. They can be separated by evaporation. C.
7.6: Classifying Separation Techniques. We can separate an analyte and an interferent if there is a significant difference in at least one of their chemical or physical properties. Table 7.6.1 provides a partial list of separation techniques, organized by the chemical or physical property affecting the separation.
A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase. Figure 9.1.1 9.1. 1 : Oil and water do not mix, instead forming two distinct layers called phases. The oil phase is less dense than the water phase, and so ...

Define evaporation. The change of a substance from a liquid to a gas. Define distillation. the process of separating.
A mixture is composed of two or more types of matter that can be present in varying amounts and can be physically separated by using methods that use physical properties to separate the components of the mixture, such as …
Centrifuges. In centrifuges, a centrifugal force, generated by high speed rotations, is used to separate solids from liquids. Centrifugation can be used to recover solids from slurries, …

Distillation uses boiling to separate mixtures of liquid solutions. It takes into account that different substances in the mixture will have different boiling points. For example, if you heat salt water the water in the solution will boil before the salt. The water will then evaporate leaving the salt behind.
The choice of techniques of separating mixture depends upon mixture type and difference in the chemical properties of the components of the mixture. …
