Chemistry.Chapter.4
| Question | Answer |
|---|---|
| Hydration | Combination with water |
| Solution | Homogeneous mixture. A sample of matter consisting of more than one pure substance with properties that do not vary within the sample. |
| Aqueous Solution | A substance dissolved in water |
| Solute | A substance dissolved in a solvent to make a solution |
| Solvent | The most abundant component in a solution. Usually water. |
| Electrolyte | A substance that dissociates fully or partially into ions when dissolved in a solvent, producing a solution that conducts electricity. |
| Strong Electrolyte | a solute that completely dissociates into ions in solution and conducts electricity. |
| Weak Electrolyte | a solute that incompletely dissociates into ions in solution. Conducts a low amount of electricity |
| Nonelectrolyte | a substance that does not ionize in a solution or conduct any electricity |
| Acid | a compound containing detachable hydrogen ions |
| Strong Acid | an acid that completely dissociates into hydrogen ions and anions in solution. A strong electrolyte |
| Weak Acid | An acid that only partially dissociates into hydrogen ions and anions in solution. |
| Weak Base | A weak electrolyte that only partially dissociates into ions in solution |
| Molarity | Molar concentration |
| Standard Solution | A solution of precisely known concentration |
| Dilution | Adding solvent to a solution to lower its concentration |
| Precipitate | An insoluble substance that has been formed from substances dissolved in a solution |
| Soluble | Capable of being dissolved in a solvent |
| Insoluble | a substance that does not dissolve in a solvent to any significant degree |
| Spectator Ions | an ion that appears as both a reactant and a product in an ionic equation |
| Equivalence Point | the point in a titration when enough titrant has been added to react completely |
| Indicator | A substance that undergoes an sharp, easily observable change when conditions in its solutions change |
| Endpoint | The experimental estimate of the equivalence point in a titration |
| Oxidation | the loss of one or more electrons by an atom, molecule, or ion. |
| Reduction | the gain of one or more electrons by an atom, molecule, or ion |
| REDOX | A reaction that involves transfer of electrons from one substance to another |
| Oxidation State | A convention for representing a charge of an atom embedded within a compound |
| Oxidizing Agent | A reactant that removing electrons from other reactants in a chemical reaction |
| Reducing Agent | A substance that supplies electrons to another reactant in a chemical reaction |
