1. What is a SOLUTION? - Def and give examples
2. What is an Alloy? -Give an example.
3. Complete the Venn Diagram:

-List 2
characteristics
of solutes
-Ex.
Solvent
Similarities
they both
share
List 2
characteristics
of solvents
-Ex.
4. In 5-10 sentences, explain how a substance is DISSOLVED.
Types of Solutions
Saturated Solution
Dependent on:
Unsaturated Solution
Solubility
Supersaturated Solution
Solubility Curves
Different
Concentrations:
-Contains all of the solute it can hold
at a certain temperature.
-If you added more solute, it would
not dissolve.
-Can dissolve MORE solute at a certain
temperature.
-If you add more solute, it would dissolve.
-A saturated solution can become an
UNSATURATED if you INCREASE THE
TEMPERATURE
-Contains MORE SOLUTE than a saturated
solution at the same temperature
-Made by increasing SOLVENT TEMP
-Unstable
-If you added more solute, it would not
dissolve
-The properties of the SOLUTE and
SOLVENT
-CONCENTRATED = LARGE amount of
SOLUTE in the solvent
-Ex: Canned OJ
-DILUTE = SMALL amount of SOLUTE
in the solvent
-Ex: Watered down
-Graph that tells you how much
SOLUTE will DISSOLVE at any
temperature on the graph
Dissociation
Nonelectrolytes
Electrolytes
Ionization
-Compounds that produce solutions of
IONS that conduct electricity in water
-Ex: Ionic Compound = NaCl, vinegar
-Compounds that DO NOT form
IONS in water and CAN NOT
conduct electricity.
-Ex. Covalent Compounds = Sugar
-Process where an IONIC
SOLID SEPARATES into
POSITIVE and NEGATIVE
IONS
-Happens when the ionic solid
is placed POLAR WATER
-Process where IONS are formed
from neutral atoms that are broken
apart
-Happens when placed in NEUTRAL
WATER
