| solvent | a substance that dissolves a solute to make a solution (larger amount) |
| solute | the substance that is dissolved in a solution (smaller amount) |
| What is a universal solvent? | A solvent that dissolves many solutes for example water |
| Mixture | 2 or more atoms that are not chemically combined |
| Heterogeneous mixture | you can see all the different parts of the mixture easily |
| Homogeneous mixture | you cannot see all the different parts easily |
| Solubility | a measure of how easily a solute will dissolve in a solvent |
| Dilute Solution | a solution with only a small amount of solute |
| Concentrated Solution | a solution with only a large amounst of solute |
| Saturated Solution | A solution that cannot hold any more solute at a certain temperature. |
| Temperature | a factor that can affect solubility. if you increase the temperature, then the solution can dissolve more solvent. |
