4. Solutions
Solutions
Solutions can be made from any combination of solids, liquids, and gases. Solutions are homogeneous mixtures.
If sugar is added to water, water is the__________________and sugar is the _______________.
Adding more sugar makes the solution more ___________________.

5. Solutions Colloids and Suspensions
Colloids and suspensions are classified by the size of their particles. What are the particles of a suspension?
If a suspension is shaken up and then left to sit, what will happen to the particles?
List some examples of each…

6. Solutions Forming a Solution
Explain what occurs as sodium chloride, an ionic solid, dissolves in water.

7. Solutions
Effect of De-icing Fluid on the Freezing Point of Water

8. Working With Solubility
Pickling requires saturated solutions of salt in water.

9. Working With Solubility
Solvents and Solubility
Some polar and nonpolar compounds form layers when they are mixed together. Which of these liquids are polar and which are nonpolar?

10. Working With Solubility
Supersaturated Solution
Dropping a crystal of solute into a supersaturated solution causes the extra solute to rapidly come out of solution.

11. Working With Solubility
Crystallized honey, a supersaturated solution, can be more than 70 percent sugar. Remember: a saturated solution cannot dissolve any more solute into the solvent….it is as filled up as possible with solute.
