  • Suspension
  • Colloid
• Ways of separating mixtures

  • Decantation
  • Evaporation
  • Filtration
  • Magnetism or using magnets
  • Sieving
  • Floatation
  • Distillation
  • Physical separation or hand picking
  • Winnowing
  • Chromatography
• Decantation

  Technique used in separating heterogeneous mixtures made up of solid and liquid or two liquids with different density
• Mixtures that can be separated by decantation

  • Sand and water
  • Oil and water
• Evaporation

  Process in which a liquid changes into gaseous form on heating, allowing the liquid to evaporate leaving the soluble solid behind
• Filtration

  Used to separate insoluble solid from a liquid, using a filter like mesh cloth or filter paper
• Mixture that can be separated by filtration

  • Liquid with tiny particles of solid
• Magnetism or using magnets

  Used to separate metals and non-metals, as metals are attracted to magnets and non-metals are not
• Mixture that can be separated by magnetism

  • Sand and iron fillings
• Sieving or sifting

  Method used in separating mixture with big and fine particles using a strainer or a big screen
• Mixtures that can be separated by sieving

  • Sand and gravel
  • Flour
• Winnowing

  Method in which heavier components of the mixture are separated from the lighter substances with the help of the wind
• Floatation

  Works for things that are less dense than another substance, like leaves floating in water
• Distillation

  Process of separating liquids from a solution based on differences in boiling points
• Physical separation or hand picking

  Technique used in separating solid components of heterogeneous mixture that are big enough to be seen and picked by hand
• Chromatography

  Technique that separates the components of a mixture based on their ability to travel at different speeds across a surface
• Chromatography

  • Dissolved substances with different colors, such as ink and plant dyes
• Evaporation is the process where liquid turns into gas, leaving behind solid particles or other substances that do not evaporate.
• Filtration is used to separate solids from liquids.
