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
Methods
• Decantation
– 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
