Colloid | A mixture containing small, undissolved particles that do not settle out. |
Suspension | A mixture in which particles can be seen and easily separated by settling or filtration. |
Dilute Solution | A mixture that has only a little solute dissolved in it. |
Concentrated Solution | A mixture that has a lot of solute dissolved in it. |
