Chemistry

• Sieving


  use of sieve to separate solids with different sizes
• Sedimentations


  settling of particles
• Decantation


  let particles settle then pour into separate containers
• Centrifugation


  high-speed spinning for faster sediment settling
• Separation


  very similar to decantation but with different equipment (instead of pouring, it comes out of a tap)
• Freeze concentration


  based on different freezing points, one solidifies(or freezes) then it can easily be removed
• Evaporation

  use of heat to collect more stable substance (different from boiling)
• Distillation


  used to collect more volatile substance (liquid-gas-condense to liquid)
• Fractional Distillation

  separated by boiling points then condensed
• Liquefaction


  gas/solid to liquid by promoting condensation then fractional distillation occurs
• Electrolysis


  uses of electric current through liquid with ions
• Crystallization


  occurs at areas with high organization
