Basic explanations of solutions, suspensions, and colloids

2.  A solution is formed
when substances
dissolve and form a
homogeneous mixture
 Can not be filtered
 Small particles
 A suspension is a
heterogeneous
mixture that
separates into layers
over time
 Can be filtered
 Large particles

3. Salt is known as the solute
(substance that dissolves In the
solvent)
Water is known as the solvent
(substances that dissolves the
solute)
Final mixture is known as the
solution.

5. Substance 1 Solute or
solvent?
Substance 2 Solute or
solvent?
Example
A Carbon
Dioxide
Water Carbinated
drinks
B Water Salt Saline
solution
C Alcohol Iodine Iodine
solution
D Dishwashing
detergent
Oil Dirty
Dishes

6. When a solid does not dissolve in a
liquid, a suspension is formed
A suspension is a mixture in which
insoluble particles are suspended in
a liquid or gas

8.  Contains particles in between the small
particles in a solution and the large particles
in a suspension.
 Do not separate into layers
 Cannot use a filter
 Heterogeneous mixture

9. Colloidal particles can scatter a
beam of visible light because of its
smaller size.
