Terms | Definitions |
|---|---|
 Solution | A homogeneous mixture |
| Concentrated | Solution containing a large amount of solute |
| Dilute | A solution that contains a small amount of solute |
| Solute | Small amount of dissolved particles in a solution |
| Solvent | The dissolving medium in a solution |
| Miscible | liquids that dissolve freely in one another in any proportion |
| Immiscible | liquid solutes and solvents that are not soluble in each other |
| Endothermic | energy is absorbed |
| Exothermic | gives off heat |
| Homogeneous Solution | a mixture in which you cannot see the different parts |
| Heterogeneous Solution | A mixture in which different parts can be easily distinguished |
| Universal Solvent | Water- due to its polarity and ability to dissolve many different solutes |
| Polar | having a pair of equal and opposite charges |
| Nonpolar | a molecule in which all atoms have the same electronegativity and the electron distribution is equal |
| Electrolyte | a solution that conducts electricity |
| Nonelectrolyte | A substance that dissolves in water to give a solution that does not conduct an electric current |
| Solvation | Process of dissolving |
| Hydration | solvation where the solvent is water |
| Unsaturated | able to add more |
| Saturated | maximum quantity |
| Supersaturated | more than the maximum quantity |
| Visocosity | resistance to flow(thickness) |
| Percent by mass | a percentage determined by the ratio of the mass of each element to the total mass of the compound |
| Percent by volume | volume of solute/volume of solution x 100 |
| Solubility | the quantity of a particular substance that can dissolve in a particular solvent (yielding a saturated solution) |
| Colloid | a mixture with properties between those of a solution and fine suspension |
| Suspension | a mixture from which some of the particles settle out slowly upon standing |
| Tyndall Effect | the phenomenon in which light is scattered by very small particles in its path |
| Brownian Motion | the chaotic movement of colloidal particles, caused by collision with particles of the solvent in which they are dispersed |
| Precipitates | When a stream becomes saturated with ions, they crystallize and settle out of solution becoming _________ |
