| Question | Answer |
|---|---|
| Solute | the substance dissolved in a solution |
| Solvent | the dissolving medium in a solution |
| Solution | a homogeneous mixture of two or more substances in a single phase |
| Aqueous | any solution in which water is the solvent |
| Freezing point depression | difference between the freezing points of a pure solvent ans a solution of a non-electrolyte in that solvent |
| Boiling Point elevation | the difference between the boiling point of a pure solvent and a non-electrolyte of that solvent |
| Saturated | solution that contains the maximum amount of dissolved solute |
| Unsaturated | solution that contains less solute than a saturated solution under the existing conditions |
| Supersaturated | a solution that contains more dissolved solute than a saturated solution contains under the same conditions |
| Distillation | technique of heating a liquid to create a vapor which is collected when cooled separate from the original liquid |
| Filtering | method of chemical filtering that lowers the carbonate hardness and pH of aquarium water |
| Chromatography | method of separating and analyzing mixtures of chemicals |
| Solubility | the amount a substance required to form a saturated solution with a specific amount of a solvent at a specified temperature |
| Mixture | a blend of two of more kinds of matter, each of which retains its own identity and properties |
| Homogeneous | having a uniform composition throughout |
| Heterogeneous | not having a uniform composition throughout |
| Suspension | mixture in which the particles in the solvent are so large that they settle out unless the mixture is constantly stirred or agitated |
| Colloid | a mixture consisting of particles that are intermediate in size between those in solutions and suspensions forming mixtures known as colloid dispersions |
| Disassociation | the separation of ions that occurs when an ionic compound dissolves |
| Electrolyte | substance that dissolves in water to give a solution that conducts electric current |
| Non-electrolyte | substance that dissolves in water to give a solution that does not conduct an electric current |
| Precipitate | solid that is produced as a result of a chemical reaction in solution and that separates from the solution |
| Ionic equation | equation that includes only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution |
| Molecular equation | equation for a chemical reaction in which all formulas are written as if all substances existed as molecules |
| Spectator ion | ion that does not take part in a chemical reaction and is found in solution both before and after the reaction |
| Acid | chemical species that donates protons or hydrogen ions and/or accepts electrons |
| Base | chemical species that donates electons or hydroxide ions or that accepts protons |
| Neutralization | the reaction of hydronium ions and hydroxide ions to form water molecules |
| Oxidation | reaction in which the atoms or ions of an element experience an increase in oxidation state |
| Reduction | reaction in which the oxidation state of an element decreases |
| Molarity | number of moles of solute in one liter of solution |
| Molality | concentration of a solution expressed in moles of solute per kilogram of solvent |
| Dilution | process of reducing the concentration of a solute and a solution usually simply by mixing with more solvent |
| Titration | controlled addition and measurement of the amount of a solution of known concentration required to react completely with a measured amount of a solution of unknown concentration |
| Concentration | measure of the amount of solute in a given amount of solcent or solution |
