Term
|
Definition
| Suspension is a mixture where the particles can be visible and seperated by settling and filtration. An example, would be a snow globe. |
|

Term
|
Definition
| Colloid is a mixture that has particles bigger than ones in solution but it can not be seen. It can scatter light beams. Fog, milk and Jello and examples. |
|

Term
|
Definition
| Solvent is the part of a solution that makes up the largest amount. |
|
|
Term
|
Definition
| Solute is the substance present in a solution ina small amount and it can dissolved by the solvent. |
|
|
Term
Explain about water, the solvent. |
|
Definition
Without water, there would be no life. Cells are made mostly of water and dissolved chemicals. Digestion takes place in water solutions. Plants get their nutrients from the water solution in the soil. |

Term
|
Definition
Gasoline is a solution of several different liquid fuels. Solutions are made up of any combination of gas, liquid or solid. |

|
Term
| What happens when a solution forms? |
|
Definition
| When a solution forms, the particles of solute leave each other and become surrounded by particles of solvent. |
|
|
Term
| What happens when an Ionic solid dissolves in a solution? |
|
Definition
| The negative and positive ions are attracted to the polar water molecules. The water molecules surround themselves with each ion as it leaves to the surface of crystal. The more molecules exposed, the more ions dissolve. |
|
|
Term
| Describe Molecular solutes. |
|
Definition
The polar water molecules attract polar sugar molecules. This causes sugar molecules to move away from eac other. But covalent bonds aren't broken. |
|
|
Term
|
Definition
Little solute in the mixture |
|
|
Term
|
Definition
| More solute in the mixture |
|
|
Term
|
Definition
The measure of how well a solute can dissolve at a given temperature. |
|
|
Term
Define saturated and unsaturated solution. |
|
Definition
If solution no longer can dissolve any more solue then it is called saturated. As long as solution can continue dissolving solute then it is called unsaturated. |
|
|
Term
|
Definition
These occur in non-normal lconditions. Soda with carbonation is a supersaturated solution where CO2 is dissolved at high pressure and sealed. |
|
|
Term
| How does Temperature affect solubilty? |
|
Definition
For liquids high temperature means better solubilty. For gases high temperature and high pressure means better solubilty. |
|
|
Term
|
Definition
| Polar will dissolve in polar and nonpolar will dissolve in nonpolar. |
|
|
Term
| Solutes effects on solutions |
|
Definition
| Will decrease freezing point and it will raise boiling point. |
