Key Concepts

  • FiltrationUsed to separate an insoluble solid from a liquid. The mixture is poured through filter paper in a funnel.
  • EvaporationUsed to obtain a dissolved solid from its solution. The solution is heated until the solvent evaporates.
Did you know? Sea salt is obtained from seawater by natural evaporation in shallow pools called salt pans!

Theory

Filtration separates insoluble solids from liquids using filter paper. Sand does not dissolve in water, so it can be separated by filtration.
