| The part of the 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 containing small, undissolved particles that do not settle out. | colloid |
| A mixture in which particles can be seen and easily separated by settling or filtration. | suspension |
