Separation Techniques

• Heterogeneous mixtures have visible layers of boundaries and a non-uniform composition.
• Homogeneous mixtures do not have visible phases or boundaries and have a uniform composition.
• Changes of state occur through the addition or removal of heat and the resultant change in temperature.
• Filtration


  A separation technique used to separate a mixture of an insoluble solid in a liquid.
• Evaporation


  A separation technique used to separate a homogeneous mixture through evaporating the solvent and leaving the solute behind.
• Solvation


  A separation technique used to separate a heterogeneous mixture based on the differences of solubility; one of the substances is soluble in a solvent, but the other solid is insoluble.
• Distillation


  A separation technique used to separate a mixture of two liquids with different volatility or boiling points.
