- 1solute + solvent = ?solution!
- 2Solids dissolve in water to make a solution. These solids are soluble.A solution is made from a solute (solid) and a solvent (liquid).
- 3Solids that don't dissolve are insoluble.Insoluble solids make water go cloudy and the solids sink to the bottom.
- 4The total mass of a solution equals the mass of solvent added to the mass of the solute.Water- most common solute
- 5If you keep adding solutes to a solvent, eventually the solvent will not dissolve. This is called a saturated solution.It can still dissolve if you add more solvent or increase the temperature
- 6Filtration- used to separate solid particles which do not dissolve in the liquid they are in
- 7Evaporation- used to separate dissolved substances from a solution e.g. salt water
- 8Destillation (evaporation followed by condensation)- used to separate the liquid from the dissolved solid in a solution or one liquid from a mixture of liquids e.g. ink and water
- 9Chromatography- used to separate individual colours from a mixture of colours e.g. ink
