| Why is water the universal solvent? |
|
Definition
| Because it is a polar molecule. It's structure of negative and positive atoms makes it pull substances apart (dissolving them). |
|
|
Term
| What is meant by water being a polar molecule? |
|

Term
|
Definition
| The ability of one substance to dissolve in another substance at a certain temperature and pressure. |
|
|
Term
| What does it mean if something is highly concentrated? |
|
Definition
| There is a lot of solute in the solvent. |
|
|
Term
| What is a saturated solution? |
|
Definition
| A saturated solution is a solution in which no more solute can be dissolved in it at that certain temperature and pressure. |
|
|
Term
| What is a supersaturated solution? |
|
Definition
| A solution in which more solute has been dissolved into a saturated solution because the temperature and/or pressure has been changed. |
