- 1Define mixtureA substance containing two or more pure substances that can be easily separated using physical processes
- 2Define solutionA combination of a solvent and a solute
- 3Define insolubleCannot be mixed together, one does not dissolve inside the other
- 4What is a colloid?A cloudy mixture containing particles larger than those of a solution but smaller than those of a suspension.
- 5What is a suspension?An insoluble mixture where one mixture begins by floating above or in the other but slowly sinks to the bottom.
- 6What is a solution?A mixture between a solute and a solvent.
- 7Explain sievingIn this method, a mixture is poured into a sieve, separating larger particles from smaller ones.
- 8Explain filteringIn this method, a mixture is poured through a filter paper-lined funnel, separating larger particles from smaller ones.
- 9Explain magnetic separationIn this method, a magnet is hovered above a mixture, attracting metal components and fragments out of the mixture.
- 10Explain evaporationUsing a Bunsen burner and evaporating basin, a mixture is heated, evaporating liquid particles and leaving solid ones behind.
- 11Explain crystallizationIn this method, a solution is cooled, forming solid crystals. This method can also consist of slowly evaporating mixtures.
- 12Explain decantingIn this method, a suspension is left to rest, letting heavier particles sink to the bottom.
- 13Explain chromatographyIn this method, ink or dye is soaked in water and left to rest, letting the colours separate.
