|
A mixture containing particles that settle out if left undisturbed. |
Suspension. |
|
|
A solid-like mixture than when stirred or agitated, flows like a liquid (toothpaste). |
Thixotropic. |
|
|
A heterogeneous mixture of intermediate sized particles. |
Colloid. |
|
|
Brownian motion. |
Named for the Scottish botanist, Robert Brown, who noticed the random movements of pollen grains dispersed in water. Colloids make jerky, random movements. The erratic movement of colloid particles. |
|
|
Dispersed colloid particles scatter light. |

|
|
Substance that does not dissolve in a solvent. |
Insoluble. |
|
|
Two liquids that can be mixed together but separate shortly after. |

|
|
Process of surrounding solute particles with solvent particles to form a solution. |
Solvation. |
|
|
Overall energy change that occurs during the solution formation process. |

|
|
Contains the maximum amount of dissolved solute. |
Saturated solution. |

|
Contains more dissolved solute than a saturated solution at the same temperature. |
Supersaturated solution. |
|
|
States that at a given temperature the solubility of a gas in a liquid is directly proportional to the pressure of gas above the liquid. |
Henry's law. |
|
|
Vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure. |
Colligative properties. |
|
|
Caused by number of solute particles in a solution. |

|
Temperature difference between a solutions boiling point and a pure solvents boiling point. |
Boiling point elevation. |
|
|
The difference in temperature between its freezing point and the freezing point of its pure solvent. |
Freezing point depression. |
|
|
Diffusion of a solvent through a semipermeable membrane. |
Osmosis. |
|
|
Amount of additional pressure caused by the water molecules that moved into the concentrated solution. |
Osmotic pressure. |
