| Solids dissolve in water to make a solution. These solids are soluble. | A solution is made from a solute (solid) and a solvent (liquid). |
| Solids that don't dissolve are insoluble. | Insoluble solids make water go cloudy and the solids sink to the bottom. |
| The total mass of a solution equals the mass of solvent added to the mass of the solute. | Water- most common solute |
| If 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 |
