| Adhesion | The force of attraction that exists between particles made of unlike substances |
| Aerosol | A liquid in gas colloid |
| Brownian Movement | The random movement of suspended particles |
| Cohesion | The force of attraction between substances of similar composition |
| Colloid | A mixture that does not settle, does not filter, but does show tyndall effect; particles are of medium size |
| Dissolve | To cause the molecules of one substance to become separated from each other and become scattered in between the molecules of another substance, the action of a solvent on a solute |
| Emulsion | A liquid in liquid colloid |
| Evaporate | A liquid changes into a gas as molecules moving from the surface of the liquid into the air. |
| Filtrate | That substance (usually a liquid) that has passed through filter paper during the filtering process |
| Foam | A gas-in-liquid colloid |
| Gel | A solid-in-liquid colloid, that has the consistency of jelly |
| Heterogeneous | Composed of parts of different kinds; not the same throughout |
| Homogeneous | Composed of parts all of the same kind; the same throughout |
| Insoluble | A solute not able to dissolve in a given solvent |
| Mixture | Matter that consists of two or more parts that can be separated by physical means |
| Precipitate | A solid substance that separates out of a solution, usually the result of a change in solubility or a chemical reaction; something that was dissolved but is no longer dissolved |
| Saturated Solution | Under standard conditions, a solution in which the maximum possible amount of solute has been dissolved |
| Soluble | Able to be dissolved in a solvent |
| Solubility | The ratio of the mass of solute to the volume of solvent in which it can be dissolved usually expressed in grams/ml or grams/100ml; the property of being able to dissolve |
| Solute | Anything that dissolves in a solvent |
| Solution | A homogeneous mixture containing a dissolved substance; a mixture that cannot be separated by filtering, does not exhibit Tyndall effect and does not separate by settling |
| Solvent | The material that acts on a solute to make it dissolve |
| Supersaturated solution | A solution that holds (keeps dissolved) more solute than it should be able to hold at a certain temperature |
| Suspension | A heterogeneous mixture in which particles of a substance are temporarily mixed in a liquid; the particles are usually of a size that cannot pass through filter paper, they will scatter light (Tyndall) and they will normally settle to the bottom over time |
| Tyndall Effect | The scattering of light as it is passed through a mixture that is not a true solution but is a colloid or a suspension |
| Unsaturated solution | A condition in which the solvent is not filled with as much solute as can be dissolved in the solvent at that temperature and pressure |
