| Term | Definition |
| Soluble | Describes a substance that can be dissolved in a given solvent |
| Insoluble | Describes a substance that cannot be dissolved in a given solvent |
| Immiscible | Describes two liquids that can be mixed together but separate shortly after you cease mixing them |
| Miscible | Describes two liquids that are soluble in each other |
| Solvation | The process of surrounding solute particles with solvent particles to form a solution; occurs only where and when the the solute and solvent particles come in contact with each other |
| Concentration | A quantitive measure of the amount of solute in a given amount of solvent of solution |
| Heat of Solution | The overall change that occurs during the solution formation process |
| Henry's law | States tat at a given temperature, the solubility of a gas in a liquid is directly porportional to the pressure if the gas above the liquid |
| Molarity | The number of moles of solute dissolved per liter of solution; also known as molar concentration |
| Mole fraction | The ratio of the number of moles of solute in a solution to the total number of moles of solute and solvent |
| Saturated Solution | Contains the maximum amount of dissolved solute for a given amount of solvent at a specific temperature and pressure |
| Solubility | The maximum amount of solute that will dissolve in a given amount of solcent ata specific temperature and pressure |
| Supersaturated Solution | Contains more dissolved solute than a saturated solution at the same temperature |
| Tyndall effect | The scattering of light by colloidal particles |
| Unsaturated solution | Contains less dissolved solute for a given temperature and pressure than a saturated solution; has further capacity to hold more solute |
