| Pure Substance | matter that has definite physical and chemical properties. An element or compound |
| Mixture | two or more substances that are not chemically bonded. The substances can be easily seperated. |
| Solution | "well-mixed" mixture; One substance is completely dissolved in another |
| solute | substance present in a solution in the smaller amount; dissolved by the solvent; can be liquid, solid, gas |
| solvent | substance present in a solution in the larger amount; dissolves the solute; most common solvents are liquids; the MOST common solvent is water (the "Universal Solvent") |
| suspension | mixture where the particles are big enough to see (ex. orange juice with pulp) |
| saturated | a solution that contains as much solute as it can dissolve (hold) at a given temperature; if you added more solute it wouldn't dissolve |
| super saturated | a solution that is able to hold more solute than normal at a given temperature; if temperature increases solvent will hold more solute; if pressure increases solvent will be able to dissolve more solute |
| soluble | a substance that WILL dissolve in a solution |
| insoluble | a substance that WILL NOT dissolve in a solution |
| dilute solution | a solution with very little solute dissolved in it |
| concentrated solution | a solution with a lot of solute dissolved in it |
| miscible | two liquids that dissolve in one another (ex. water and alcohol) |
| immiscible | two liquids that do not dissolve in one another (ex. oil and water) |
| solubility | a measure of the amount of solute in a solvent at a given temperature; affected by temperature, pressure, type of solvent |
| colloid | mixture containing small particles that do not dissolve or settle out (ex. milk, jello, fog) |
