Separation of a Mixture

Introduction: Mixtures are not unique to chemistry; you use and consume them on a daily basis. The beverages you drink each morning, the fuel you use in your automobile, and the ground you walk on are mixtures. Very few materials that you encounter are pure. Any material made up of two or more substances that are not chemically combined is a mixture. The isolation of pure components of a mixture requires the separation of one component from another. Techniques needed to do this separation take advantage of the differences in physical properties of the components. The techniques you will use in this lab include the following:
