1. MIXTURES
• Matter that can be made up of 2 or
more substances PHYSICALLY mixed
together.
• The substances that make up a
mixture can be present in any amount.
• Can be separated by PHYSICAL
means

2. 2 KINDS OF MIXTURES:
• HETEROGENEOUS MIXTURES
– DO NOT APPEAR THE “SAME”
THROUGHOUT
– “LEAST MIXED”
– PARTICLES ARE LARGE
ENOUGH TO BE SEEN

3. • HOMOGENEOUS MIXTURES
– Appear to be the same
throughout
– “Well Mixed”
– Particles are very small--can’t
be seen

4. SOLUTIONS
• A type of homogeneous mixture
formed when one substance
dissolves in another
• “Best Mixed” of all mixtures

5. SOLUBILITY
• SOLUTE: The substance that is
dissolved in a solution
• SOLVENT: The substance that does
the dissolving in a solution
– Water is the most common solvent
– Water is the “UNIVERSAL
SOLVENT”, since it can dissolve
many substances

6. • SOLUBILITY: The amount of a solute
that can be dissolved in a given amount of
solvent
• SOLUBLE: Term that describes a
substance that dissolves in another
substance
• INSOLUBLE: Term that describes a
substance that does not dissolve (or very
little dissolves) in another substance

7. TYPES OF SOLUTIONS
• DILUTE SOLUTION
– A solution in which a little amount
of solute is dissolved in a large
amount of solvent.
• CONCENTRATED SOLUTION
– A solution in which a lot of solute
is dissolved in a small amount of
solvent.
