| a very well-mixed mixture, having the same properties throughout | Solution |
| the part of a solution that is present in the largest amount and dissolves a solute | Solvent |
| the part of a solution present in a lesser amount and dissolved by the solvent | Solute |
| a mixture with small undissolved particles that do not settle out | Colloid |
| a mixture that has only a little solute dissolved in it | Dilute Solution |
| a mixture that has a lot of solute dissolved in it | Concentration solution |
| a measure of how well a solute can dissolve in a solvent at a given temperature | Solubility |
| a mixture that contains as much solute in it as possible at a given temperature | Saturated solution |
| a mixture in which more of the same solute can be dissolved | Unsaturated solution |
| a mixture that has more dissolved solute than is predicted by its solubility at the given temperature | Supersaturated solution |
