- 1SolubleA substance that will dissolve.
- 2Solute:The name given to the substance that will dissolve in a liquid.
- 3SolventThe liquid in which something is dissolved
- 4SolutionWhat is formed when a solute has dissolved in a solvent.
- 5Saturated SolutionA solution in which no more solute can dissolve.
- 6DissolveWhen a substance mixes completely with a solvent.
- 7PureA substance that has not been mixed with other substances.
- 8InsolubleA substance that will not dissolve.
- 9ImpureA substance that has more than one substance mixed with it.
- 10FiltrateThe name given to the liquid that is collected after filtering.
- 11EvaporateThe change of state from a liquid to a gas.
- 12Simple DistillationWe use simple distillation to separate two different substances in a mixture by boiling the substance with a lower boiling point and then feeding it through a tube (with coolants to speed up the process) into a separate container .
- 13Fractional distillationFractional distillation can be used to separate two or more liquids. In this example, they are ethanol and water. Ethanol can be separated from the solution because the liquids have different boiling points. An electric heater needs to be used so the temperature can be more exact. Similarly to simple distillation, the gas is then transported through a cooled tube to a container.
- 14FiltrationFiltration can separate an insoluble solid from a liquid. It involves A funnel, filter paper and some containers. By placing the filter paper on the funnel and then pouring the solid and liquid onto the paper, the clean liquid goes through and the solids get stuck.
- 15CrystallisationCrystallisation is very simple. You need an evaporating basin and heat. Crystallisation can be used to produce solid crystals from a solution. The solvent is evaporated completely leaving only the solids that were once part of the solution. An example of this happening is in a salt flat where there used to be a solution of water and salt but all the water evaporated leaving crystals of salt.
- 16Paper ChromatographyPaper Chromatography is used to separate mixtures of soluble substances such as dyes, inks or pigments. The image shows how lighter colours move further up the paper.
