The Separation of the components of a Mixture 1011 The Separation of the components of a Mixture

Safety Put on Goggles And Apron

Objectives Demonstrate Separation of a Mixture Investigate Different Techniques for Separating Mixtures Using their Physical Properties

Mixtures Any Material Made up to Two or More Substances Not Chemically Combined Isolation of Pure Components Based on Their Physical Properties

Methods Five Methods of Separation Magnetic Separation Use Magnet to Separate Ferromagnetic (Iron Fillings) Extraction Solvent Selectivity – Separating Soluble Solid from Insoluble In this experiment We will use Five Methods of Separation

Methods Decantation Filtration Separation of Liquid of Soluble Solid from Insoluble Solid (Pouring) Filtration Separation of Solid from Liquid via a Porous Material (Filter Paper, Charcoal, Sand, etc.) Allows Liquid to Pass Through but not Solid

Methods Evaporation Removing Liquid by Heating until Dry Component Remains

Experiment Mixture Contains: Iron Fillings (Fe) Copper (II) Sulfate (CuSO4) Sand (SiO2)

Experiment Use Magnet to Remove Iron Fillings Dissolve Copper Sulfate with Water to Extract Filter Sand/Copper Sulfate Mixture Evaporate Water to Recover Dry Copper Sulfate and Sand

Calculations

Weight of Iron Fillings Weight of Watch Glass and Mixture – Weight of Watch Glass and Mixture After Removing Iron Fillings

Weight of Copper Sulfate Weight of Beaker 1 and Copper Sulfate – Weight of Beaker 1

Weight of Sand Weight of Beaker 2 and Sand – Weight of Beaker 2

Weight of Recovered Solids Weight of Iron Fillings + Copper Sulfate + Sand

Percent Yield Percentage of Recovered Solid Weight of Recovered Solid – Weight of Mixture X 100

Percentage of Iron Weight of Iron Fillings – Weight of Mixture X 100

Percentage of Copper Sulfate Weight of Copper Sulfate ÷ Weight of Mixture X 100

Percentage of Sand Weight of Sand ÷ Weight of Mixture X 100
