Solutions Vocab
Term | Definition |
---|---|
Colloid | A mixture with medium sized particles that do not settle out; generally uniform appearance |
Concentrated | Describes a solution that contains a relatively large amount of solute |
Dilute | Describes a solution that contains a relatively small amount of solute |
Immiscible | Describes liquids that do not dissolve in each other (ex. oil and water) |
Insoluble | "does not dissolve" |
Miscible | Describes liquids that dissolve in each other (ex. alcohol and water) |
Precipitate | An insoluble solid material that is produced in double replacement reactions; it settles to the bottom of the container upon standing |
Saturated | A solution that contains the maximum amount of solute for a given amount of solvent at a particular temperature |
Solubility | The maximum amount of a solute that dissolves in a given amount of solvent at a particular temperature; produces a saturated solution |
Soluble | "dissolves" |
Solute | The dissolved particles in a solution (ex. sugar); present in the smaller amount |
Solution | A homogeneous mixture with very small particles that do not settle out of the solution; composed of a solute and a solvent |
Solvation | The process that occurs when an ionic solid dissolves; the ions are pulled apart and surrounded by solvent molecules |
Solvent | The dissolving medium in a solution (ex. water); present in the larger amount |
Supersaturated | A solution that contains more solute than it can theoretically hold at a particular temperature; unstable; excess solute will crystallize out if a "seed crystal" is added |
Suspension | A heterogeneous mixture with large particles that settle out upon standing |
Tyndall Effect | Scattering of light by particles in a colloid or suspension, which causes the beam of light to become visible |
Unsaturated | A solution that contains less solute than a saturated solution at a particular temperature |
