    • Solvent is something a solute dissolves in
    • Soluble means the substance can be dissolved
    • Insoluble means the substance cannot be dissolved
    • A substance that dissolves is usually called a solute
    • A solution is formed when a solute dissolves in a solvent
    • Filtration is a method to separate a solid and a liquid. The solid is collected on a filter paper, while the liquid passes through it and is collected in a separate container.
    •  Crystallisation is performed by heating a mixture so that the solvent evaporates. Eventually, crystals of the solute will form.
    • A compound contains two or more chemically combined elements
    • Chromatography method:
      • Draw a pencil line near bottom of paper
      • Place a sample of each ink on solvent line
      • Pour shallow layer of solvent into beaker
      • Place chromatography paper into beaker and place a lid
      • Wait for the solvent to rise and remove paper when solvent is almost at the top
