| Alloy | a homogenous mixture/solution containing at least one metal. Ex: brass |
| Aqueous | a homogenous mixture/solution in which a solute is dissolved in water. |
| Boiling Point | the temperature at which a liquid undergoes a phase change from liquid to gas; the temperature at which the vapor pressure of a liquid is equal to the atmospheric pressure. |
| Boiling Point Elevation | the boiling point of a solution is higher than the boiling point of the pure solvent (colligative property) |
| Colloid | a heterogeneous mixture composed of tiny particles suspended in another material. The particles are larger than the particles in a solution but smaller than particles in a suspension. Ex: milk |
| Concentrated | Having a relatively large amount of substance present in a unit amount of mixture. For example |
| Concentration | A measure of the amount of solute present in a unit amount of mixture. (Ex: ppm = parts per million |
| Dilute | having a relatively low concentration of solute in a mixture. |
| Freezing Point Depression | the freezing point/melting point of a solution is lower than the freezing point/melting point of the pure solvent (colligative property) |
| Heterogeneous | A sample of matter consisting of more than one pure substance and more than one phase |
| Homogeneous | A sample of matter consisting of more than one pure substance with properties that do not vary within the sample |
| Insoluble | Refers to a substance that does not dissolve in a solvent to any significant degree |
| Miscible | two liquids are considered "miscible" or mixable if shaking them together results in a single liquid phase with no visible separation |
| Mixture | two or more pure substance PHYSICALLY combined; a combination of two or more pure substances that can be separated by physical means |
| Molarity | a measure of concentration; M = moles of solute/liters of solution |
| Parts Per Million | a measure of concentration; ppm = parts of solute/million parts of solution |
| Percent Composition (by mass or volume) | % comp = (part/whole) x 100 |
| Precipitate | An insoluble substance that has been formed from a chemical reaction between substances dissolved in a solution |
| Saturated | a solution that has reached equilibrium; a solution which cannot dissolve any more solute |
| Solubility | a measure of the concentration of a substance in a saturated solution; a measure of how much of a substance can dissolve in a given amount of solvent |
| Soluble | capable of being dissolved in a solvent |
| Solution | a homogenous mixture |
| Solute | A substance dissolved in a solvent to make a solution |
| Solvent | The most abundant component in a solution |
| Supersaturated | a solution in which the concentration of solute is higher than the solubility; more solute is dissolved than should be under a given set of conditions |
| Suspension | A heterogenous mixture in which relatively large particles are suspended in a liquid |
| Tyndall Effect | Light passing through a colloid is scattered by suspended particles (the light beam becomes clearly visible) |
| Unsaturated | A solution with a concentration lower than its equilibrium solubility; a solution in which more solute can be dissolved |
