Filtration

• Filtration

  The process of separating soluble and insoluble substances
• What is produced after filtration?

  Filtrate
• What is left behind after filtration?

  Residue
• If sand and water were separated through filtration what would be the residue?

  Sand
• If sand and water were separated through filtration what would be the filtrate?

  Water
• Why is filtration not pure?

  Filtration is not pure as it is always possible for the insoluble substance to be in the filtrate.
• What is an insoluble solid?

  A solid that does not dissolve in a specific solvent
• What is the filtrate in the filtration process?

  The liquid that passes through the filter paper
• What is the residue in the filtration process?

  The solid left on the filter paper
• How does filter paper function in filtration?

  It allows pure liquids and solutions to pass through while preventing insoluble solids
• Why can sand be separated from water using filtration?

  Because sand is insoluble in water
• What happens to sand when mixed with water?

  It does not dissolve and remains as an insoluble solid
• Why do water molecules pass through filter paper while sand particles do not?

  Water molecules are small enough to fit through the holes in the filter paper
• What are the key components of the filtration process?

  • Insoluble solid
  • Filter paper
  • Filtrate (liquid that passes through)
  • Residue (solid left on filter paper)
  • Filter funnel
  • Conical flask
• What is the process of filtration?


  1. A mixture of solid and liquid is poured into a filter funnel.
  2. The filter paper allows the liquid to pass through.
  3. The insoluble solid is trapped on the filter paper.
  4. The liquid collected is called the filtrate.
  5. The solid left on the filter paper is called the residue.
• What are the steps involved in the filtration process?

  1. Mixture of solid and liquid is poured into a filter funnel.
  2. Liquid drips through the filter paper.
  3. Solid particles are caught in the filter paper.
