An iced tea mixture dissolved in water forms a solution, which is a homogeneous mixture where particles are too small to be filtered or scatter light. A suspension like flour in water is heterogeneous and particles separate over time through settling or filtering. Colloids have intermediate particle sizes between solutions and suspensions that do not separate and include mixtures like peanut butter or fog.

1. Acknowledgment
I would like to express my special thanks of gratitude to
my teacher (Mrs. Urjah Kapila ) as well as our principal
(Mrs. Gauri Chabra )who gave me the golden
opportunity to do this wonderful project on the topic
(Solutions, suspensions, colloids), which also helped me
in doing a lot of Research and i came to know about so
many new things I am really thankful to them.

2. Do You Know???
●
If you stir 2 tablespoons of Iced-tea
mix into a 16oz. Glass of water ,you
would make a delicious summer drink
.If you let the glass sit out on the
counter for several days, would that
drink be separated into its parts?

3. Solutions, Suspensions, and Colloids

4. Goal
To classify mixtures as
solutions,
suspensions, or colloids.

5. It’s all about the particles!
➢
The size of the particles has a great
effect on the properties of a mixture.
➢
You must observe a mixture’s properties
before deciding whether it is
heterogeneous or homogeneous.
➢
Mixtures get classified as solutions,
suspensions, or colloids based on
particle size.

6. Solutions
Q: When iced-tea mix is dissolved
in water, it forms what kind of
mixture?
A: HOMOGENEOUS MIXTURE
When substances dissolve and form
a homogeneous mixture, the
mixture is called a solution.
Whatever substance
there is more of is called the
solvent. The other is called the
solute (ex.)
Iced tea-the solvent is the water,
the solute is the tea mix).

7. Properties of a Solution
They do not separate into layers over
time.
• If they are poured through a filter,
none of the substances will get trapped.
• Light passes through them.
All of the particles in a solution are too
small to become separated, filter out, or
scatter light.

8. Suspensions
Flour in water, like other
liquids that need to be “shaken
well before using”, are called
suspensions.
Muddy water taken from a swamp
is another example.

9. Properties of a Suspension
Heterogeneous mixture
• Separates into layers over time.
• Filters can separate particles that make up a
suspension.
• Particles are larger than those in a solution.
• Scatter light.
Suspended particles settle out of a suspension.

10. Colloids
Colloids contain some
particles that are
intermediate between
those in a solution and
those in a suspension.
Examples include
peanut butter, pudding,
Jello, whipped cream,
and even fog!

11. 1)Suspensions are a heterogeneous mixture of two or
more substances.
2)Particles of the solute do not dissolve in the solvent
rather they remain suspended in bulk throughout.
3)The size of particles of suspension is large enough to
be visible from naked eyes. They are greater than 1
nanometer (?10?^(-9) meter).
4)It shows Tyndall effect because of their large size of
particles.
5)When it is left for some time, particles get settled in
the bottom. Therefore, it is not stable.
6)The particles in it can be separated through the
process of filtration.
7)It does not scatter light when particles are settled
because in this case suspension breaks.

12. Distinguish between solutions,
suspensions and colloids.
