| Term | Definition |
|---|---|
| Alloy | A homogenous mixture/solution containing at least one metal. Ex: brass, steel, bronze. |
| Aqueous | A homoogenous mixture/solition in which a solute is dissolved in water. |
| Boiling Point Elevation | The boiling point of a solution is higher than the boiling point of the pure solvent (colligative property). |
| Colloid | A heterogenous mixture composed of tiny particles suspended in another mterial. The particles are larger than the particles in a solution but smaller than the particles in suspension. Ex: milk, blood. |
| Concentrated | Having a relatively large amount of substance present in a unit amount of mixture. |
| Concentration | A measure of the amount of solute present in unit amount of mixture. PPM or Molarity. |
| Dilute | Having a relatively low concentrationof 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). |
| 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. |
| 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 insolible subsance that has been formed from a chemical reaction between substances dissolved in a solution. |
| Saturated | A solution that has reached equilibrium; a soution 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 |
| Solute | A substance dissolved in a solvent to make a solution |
| Solution | A homogenous mixture |
| 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. |
| Temperature | A measure of average kinetic energy. |
| Tyndall Effect | Light passiong through a colloid is scattered by suspended particles (the light beam becomes clearly visible) |
| Unsaturated | A solution in with a concentration lower than its equilibrium solubility; a solution in which more solute can be dissolved. |
| Heterogenous | A sample of matter consisting of more than one pure substance or more than one phase |
| Homogenous | A sample of matter consisting of more than one pure substance with properties that do not vary within the sample |
| Mixture | Two or more substances physically combined. |
