  • Filtration
    Technique for separating an insoluble solid from a liquid using a barrier that retains the solid while allowing the liquid to pass through.
  • Residue
    Material left behind on the barrier after separation, typically the insoluble solid that does not pass through.
  • Filtrate
    Liquid that successfully passes through the barrier during separation, leaving the solid behind.
  • Filter Paper
    Semi-permeable membrane used to trap solids while allowing liquids to pass during separation processes.
  • Erlenmeyer Flask
    Conical laboratory container commonly used to collect liquids during separation techniques.
  • Funnel
    Device used to channel mixtures into containers and support barriers for separation.
  • Vacuum Pump
    Apparatus that creates reduced pressure to accelerate the movement of liquids through barriers.
  • Buckner Funnel
    Specialized device with a flat base, used with reduced pressure to speed up separation of solids from liquids.
  • Recrystallization
    Process where dissolved solids form crystals again, often aided by temperature reduction during separation.
  • Evaporation
    Technique for separating a soluble solid from a liquid by heating until the liquid vaporizes, leaving the solid behind.
  • Crystallization
    Formation of solid particles from a solution as the liquid component is removed, often by heating.
  • Bunsen Burner
    Heat source commonly used in laboratories to vaporize liquids during separation processes.
  • Evaporation Bowl
    Heat-resistant container used to hold mixtures during the removal of liquids by heating.
  • Semi-permeable Membrane
    Barrier that allows certain substances, typically liquids, to pass while retaining others, such as solids.
