| Question | Answer |
|---|---|
| What is a solution? | When you have one substance dissolved into another. |
| Give several examples of solution. | iced tea, coffee, tea, AIR |
| Are all solutions liquid? | NO! |
| Define solute. | The substance getting dissolved |
| Define solvent. | The substance doing the dissolving. |
| Name 3 ways to make a solution dissolve faster. | HEAT, CRUSH, AND STIR |
| What is the term that means how much solute will dissolve in a solvent at a given temperature? | Solubility |
| What do we call a solution than can hold more solute? | Unsaturated |
| What do we call a solution that is holding more solute than normal for that temperature? | Supersaturated |
| What do we call a solution that is holding just the right amount of solute for that temperature? | Saturated |

| Concentrated solutions are _____________. | Strong |
| Dilute solutions are ______________. | Weak |
| Why does increasing the surface area of the solute help it dissolve more quickly? | It brings more SOLUTE IN CONTACT WITH SOLVENT! |
