This doesn t happen often for many solids at room temperature which will help us in designing our separation procedure. Below is listed several different types of separations that are commonly used by chemist. This process uses the differing boiling points of different liquids for separation. Extraction and Filtration utilizes the solubility of a substance to permit separation. Extraction is the process of removing a substance with a greater solubility from a substance with a lower solubility.
Filtration is the process of straining a solid suspended in a liquid.
Some other common practices used in separating mixtures are called centrifugation and chromatography . Centrifugation is the process of separation a suspended solid in a liquid by high speed rotation. We will talk more about these methods later in the semester. Carefully examine the table below which details the different physical properties of the species you will be analyzing. At the beginning of lab we will talk extensively about the different separation techniques and the above table, after which time you will be asked to design a flow chart that will be used to separate the different components in this unknown mixture.
