Transcript Solution, Suspension, and Colloids (with vocab concept map)

MATTER
Sample concept
map from Tuesday’s
Activity
Anything that has mass and
takes up space (volume)
ATOM
Smallest part of a substance
that is still that substance
ELEMENT
Molecule
“Pure Substance” made of only
one type of atom;
Smallest part of a compound;
can be broken down into
elements by chemical means
MIXTURES
COMPOUND
Combinations of substances that are
not chemically combined; they can be
separated by physical means
Combination of two or more
different elements; can be
broken down into elements by
chemical means
HOMOGENEOUS
HETEROGENEOUS
Mixture whose parts are
unevenly distributed; you can
see the different parts easily
Mixture whose parts are evenly
distributed; you cannot see the
different parts easily
To review:
• A mixture is a combination of two or more
substances that are not chemically combined
• Two types:
– Homogeneous: Uniform mixture
– Heterogeneous: not the same throughout
Solution
• Two or more substances mixed so it appears to
be made of only one substance
• Particles are evenly dispersed
• Particles are small
• Cannot settle out of the mixture.
• There are two parts:
• · SOLUTE: the substance that dissolves
• · SOLVENT: the substance the SOLUTE dissolves in
• Would this be Homogeneous or Heterogeneous?
Suspension
• Particles are large and are dispersed throughout
the mixture
• Particles can block light
• Particles can settle out if the mixture is left
standing
• Parts can be separated by filtering
• Examples: Chocolate milk, orange juice, snow
globes
• Would this be Homogeneous
• or Heterogeneous?
Colloid
•
•
•
•
•
Particles are small to medium size
They can block light.
They are dispersed throughout the mixture
Cannot settle out.
Particles cannot be filtered or picked out.
• Examples: Whipped cream, Jell-o, deodorant,
shaving cream, milk
• Would this be Homogeneous or Heterogeneous?

SUSPENSION
Particles are large and can settle out
Mixture whose parts are evenly

different parts easily
COLLOID
Particles are medium
Dispersed throughout
But do not settle out
SOLUTION
Appears as one substance
Particles are small and do not settle
