Part A – Separation Techniques Mixture Physical Properties of mixture used in separation Name of separation technique Solids of different sizes Properties of the mixture such as size and shape are relied on when separating the mixture. When there is a difference between size and shape Sieving is often used as it is relatively quick. Solids and Liquids Properties of the mixture, in this case the matter of the material, are relied on as they are in different states of matter. Because of the difference in states of matter a combination of decanting and filtering can be used. The decanting will remove majority of the liquid and the filtering gets the rest of the liquid separated from the mixture. Dissolved solids in liquids Properties such as boiling point, freezing point and volatility are used to separate mixtures of this variety To separate a mixture where a substance is dissolved in a liquid is a combination of distillation and evaporation. The combination of these 2 processes will allow the liquid to separate (by evaporating) from the solid and will leave the solid in the distillation flask as crystals Liquids Properties of liquids that are used in separation include properties such as boiling point and density If the liquids have different boiling points distillation can be used to separate the solution into the different liquids. If the liquids have different densities and are insoluble then a separating funnel can be used as a separation process Gases When separating
