7. Homogeneous mixture – A mixture so evenly mixed that you can’t see the different parts (“well” mixed)

8. Solution – a homogeneous mixture in which one substance is dissolved in another substance (“best” mixed)

9. Solute – the substance that is dissolved; the substance there is less of

10. Solvent – the substance that does the dissolving; the substance there is more of

11. Tincture – a solution in which alcohol is the solvent

12. Solubility – maximum amount of solute that can be dissolved in a definite amount of solvent at a specific temperature

13. Unsaturated – solutions that contain less solute than it can possibly hold at a given temperature

14. Supersaturated – a solution that is made to hold more solute at a given temperature than is normal

15. Suspensions – a heterogeneous mixture in which the solute particles are temporarily suspended, but will eventually settle out

16. Colloids – a homogeneous mixture that is not a true solution; the solute particles are kept permanently suspended.
