Pluchino – Regents Chemistry Matter and Measurement – 08 Separation of Mixtures Aim: How are mixtures separated? Do Now: Sand, oil, isopropanol (dissolves in water) and water are mixed together in a very large beaker. How can you separate them into individual components? In a mixture, substances are physically combined, therefore we can use physical methods to separate them! Apparatus Information Filtration funnel Separates solids and liquids Solid cannot pass through filter paper Separatory funnel Separates liquids based on density Works best if the liquids do not mix with one another. Distillation Apparatus Separates liquids based on boiling point

Unformatted text preview: Will work if liquids dissolve in one another Magnet Attracts magnetic materials Centrifuge Separates solids from liquids Use this only if solids are extremely small! Chromatography Separates substances based on their ability to move in a mobile phase These techniques will not work to separate compounds into their elements. Chemical techniques must be used! Conclusions: Mixtures can be separated by using differences in physical properties These techniques will not work on pure substances. You cant just throw everything in the centrifuge!...
