| Alloy | a homogenous mixture/solution containing at least one metal: Ex: Brass, steel, bronze |
| Aqueous | homogenous mixture/solution win which a solute is dissolved in water |
| Boiling Point | temperature at which a liquid undergoes a phase change from liquid to gas: the temp at which the vapor pressure of a liquid is equal to the atmospheric pressure |
| Boiling Point Elevation | oiling point of a solution is higher than the boiling point of the pure solvent (colligative property) |
| Colloid | a hetergeneous 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, blood |
| Concentrated | having a relatively large amount of substance present in a unit amount of mixture |
| Concentration | A measure of the amt of solute present in a unit amount of mixture; Ex: ppm = parts per million, molarity - moles solute/liter solution |
| Dilute | having a relatively low concentration of solute in a mixture |
| Dissolve | when a solute "breaks apart" in the presence of a solvent (breaking of various bonds) |
| Freezing Point Depression | freezing point/melting point of a solution is lower than the freezing poiutn/melting point of th pure solvent |
| Heterogeneous | sample of matter consisting of more than one pure substance and more than one phase |
| Homogeneous | 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 | "mixable"; if shaking them together results in a single liquid phase with no visible separation |
| mixture | 2 or more pure substance physically combined; a combination of 2 or more pure substances that can be separated by physical means |
| molarity | measure of concentration: Formula: M - moles of solute/liters of solution |
| Parts per million | measure of concentration Formula: ppm - parts of solute/million parts of solution |
| Percent Composition | a measure of concentration (% comp = part/whole X 100) |
| Precipitate | An insoluble substance taht has been formed from a cheical reaction between substances dissolved in a solution |
| Saturated | solution that has reached equilibrium; a cannot dissolve any more solute |
| Solubitility | measure of the concentration of a substance in a saturated solution; a measure of how much a substance can dissolve in a given amount of solvent |
| Soluble | capable of being dissolved in a solvent |
| Solution | homogenous mixture |
| Solute | substance dissolved by a solvent to make a solution; usually least abundant component in a solution |
| Solvent | substance which causes a solute to dissolve; usually MOST abundant |
| Supersaturated | 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 | heterogenous mixture where relatively large particles are suspended in a liquid |
| Tyndall Effect | Light passing through a colloid is scatterered by suspended particiles (light beam visible) |
| unsaturated | solution with a concentration lower than its equilibrium solubility; a solution in which more solute can be dissolved |
