1. concentration: A measurement of the amount of stuff (solute) dissolved in a liquid (solvent). The most common concentration unit is molarity (M), which is equal to the number of moles of solute divided by the number of liters of solution. 2. colligative property: Any property of a solution that changes when the concentration changes. Examples are color, flavor, boiling point, melting point, and osmotic pressure. 3. dilution: When you add solvent to a solution to make it less concentrated. 4. colloid: It's a suspension. (medium sized particle) 5. dissociation: When water dissolves a compound. 6. heterogeneous mixture: A mixture where the substances aren't equally distributed. You can see different phases of matter. 7. homogeneous mixture: A mixture that looks uniform because everything is mixed up really well. 8. immiscible: When two substances don't dissolve in each other. Think of oil and water. They're immiscible. Organic compounds and water are frequently immiscible. 9. insoluble: When something doesn't dissolve. 10. molality: The number of moles of solute per kilogram of solvent in a solution. This is a unit of concentration that's not anywhere near as handy or common as molarity. 11. molarity: A unit of concentration equal to moles of solute divided by liters of solution. 12. mole fraction: The number of moles of stuff in a mixture that are due to one of the compouds. 13. saturated: When the maximum amount of solute is dissolved in a liquid 14. solubility: A measurement of how much of a solute can dissolve in a liquid. 15. solute: The solid that gets dissolved in a solution. 16. solvent: The liquid that dissolves the solid in a solution. 17. spectator ions: The ions in a reaction that don't react. 18. supersaturated: When more solute is dissolved in a liquid than is theoretically possible. 19. suspension: A mixture that looks homogeneous when you stir it, but where the solids settle out when you stop. Mud is a very short-lived suspension, while peanut butter is a very long-lived suspension. 20. unsaturated: When you haven't yet dissolved all of the solute that's possible to dissolve in a liquid.
