Study Notes
Filtration
- Involves placing filtration paper in a funnel over a beaker.
- Mixture is poured into the funnel; liquid drains into the beaker, while solid remains on the paper.
- Effective for separating mixtures of solids and liquids.
- Distinguishing physical property: state of matter (solid vs. liquid).
Evaporation
- Conducted by placing a solution in a crucible, suitable for high temperatures.
- Heating the solution with a Bunsen burner causes the liquid to evaporate.
- Useful for separating solute from solvent through the application of heat.
- Distinguishing physical property: state of matter.
Recrystallization
- Begins by dissolving an impure mixture in a hot solvent.
- The solution is covered to prevent particle escape during cooling.
- As it cools, crystals form at the bottom which can then be filtered using vacuum filtration.
- Aims to separate or remove impurities from a solid compound.
- Distinguishing physical property: size of particles.
