12. Review: What is a solution?
A solution is…
a homogeneous mixture made up of a solute and a
solvent
solution = solute + solvent
• a solid • a liquid
• is dissolved • does the dissolving
• molecules don’t move • random movement
13. How are solutes dissolved?
Solvent molecules randomly hit the solute and attack!
Example:
Solute = table salt (NaCl)
Held together by ionic bonds
Solvent = water
Polar solvent: unequal sharing
–
+
14. How are solutes dissolved?
Attack!

Movie questions:
1. What is the solute?
2. What is the solvent?
3. In your own words, describe how the salt was dissolved?
15. How are solutes dissolved?
water molecules
attack solute
overcome the
attractive forces
of the solid
dissolve the ion
16. Activity
In 3-4 sentences, describe what we just acted out.
Who were the solutes and what were the doing?
Who were the solvents and what did they do?
18. Exit Slip
1. In a solution,
a. the solvent particles are attacked by the solute.
b. the solvents are dissolved by the solutes.
c. the two substances are not evenly mixed throughout.
d. the solutes are dissolved by the solvents.
19. Exit Slip
2. Which of the following is correct statement.
a. In a solution, the solute molecules randomly move
around while the solvent molecules don’t move.
b. In a solution, the solvent molecules randomly move
around while the solute molecules don’t move.
c. A solution is an example of a heterogeneous mixture.
d. Solvents are usually solids

3. Which of the following is a correct statement about
the dissolving process?
a. The solvent molecules randomly bump into the
solutes and attack.
b. In a solution, the solvent is dissolved into the solute.
c. In a solution, the solvents are usually a solid.
d. In a solution, the solutes and solvents are unequally
mixed.
21. Exit Slip
4. An ionic salt (KBr) is dissolved into water. In this
example,
a. both KBr and water are solvents.
b. KBr (the solvent) is attacked by water (the solute),
splitting it into K+ and Br– ions.
c. KBr (the solute) is attacked by water (the solvent),
splitting it into K+ and Br– ions.
d. the KBr attacks the water and dissolves it into
solution.
22. Exit Slip
5. If the attractive forces among solid particles are
less than the attractive forces between the solid
and the liquid, the solid will
a. probably form a new precipitate as its crystal lattice
is broken and reformed.
b. be unaffected because the attractive forces within
the crystal lattice are too strong for dissolution to
occur.
c. begin the process of melting to form a liquid.
d. dissolve as particles are pulled away from the crystal
lattice by the water molecules
