|---|---|
| Soluble | A compound's ability or capability to dissolve in solution |
| Solution | A homogeneous mixture of two or more substances in a single phase |
| Solvent | The dissolving medium in a solution |
| Solute | The substance dissolved in a solution |
| Suspension | A mixture in which particles are so large that they cannot settle out unless the mixture is constantly stirred or agitated |
| Colloids | Particles that are intermediate in size between those in solutions and suspensions |
| Electrolyte | A substance that dissolves in water to give a solution that conducts electric current |
| Nonelectrolyte | A substance that dissolves in water to give a solution that does not conduct an electric current |
| Solution equilibrium | The physical state in which the opposing process of dissolution and crystallization of a solute occur at equal rates |
| Saturated solution | A solution that contains the maximum amount of dissolved solute |
| Unsaturated solution | A solution that contains less solute than a saturated solution under the existing conditions |
| Supersaturated solution | A solution that contains more dissolved solute than a saturated solution contains under the same conditions |
| Solubility | The amount of a substance required to form a saturated solution with a specific amount of solvent at a specified temperature |
