| Alloy | Homogenous mixture/solution with at least one metal (Ex: brass, steel, bronze) |
| Aqueous | Homogeneous mixture/solution in which solute is dissolved in water |
| Boiling Point | Temperature at which liquid changes to gas. Vapor pressure = atmospheric pressure |
| Boiling point elevation | The boiling point of a solution is higher than the boiling point of the pure solvent (colligative property) |
| Colloid | Heterogeneous mixture composed of tiny particles suspended in another material. Ex: milk, blood |
| Concentrated | Having relatively large amount of substance present in a unit amount of mixture |
| Concentration | A measure of the amount of solute present in a unit amount of mixture; (ppm, M); the process of increasing the amount of substance in a given amount of mixture |
| Dilute | Having a relatively low concentration of solute in a mixture |
| Freezing Point Depression | Freezing point/melting point of a solution is lower than the freezing point/mellting 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 substances 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) | % composition = (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 can not 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 a given amount of solvent |
| Soluble | Capable of being dissloved in a solvent |
| Solution | A homogeneous 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 heterogeneous 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 |
