This document discusses different types of mixtures and their characteristics. It defines a mixture as a physical combination of substances that retain their individual properties. Mixtures are categorized as either homogeneous or heterogeneous. Homogeneous mixtures like solutions are uniform mixtures where particles cannot be seen, while heterogeneous mixtures like suspensions and colloids have particles that can be seen and are suspended in another substance. The document provides examples and details on the components, properties, and types of various mixtures.

Their Characteristics

2. MIXTURE
A physical combination of two or
more substances in which each of
the substances in the mixture
retains its individual composition
and properties.
Prepared by:
Ma. Rhodora Theodorosa S. Ma. Nieva, LPT

3. TYPES OF MIXTURE
The particles of the
substances in the
mixture can still be
seen and identified.
All the substances are
evenly distributed and
create a uniform
composition.

5. HOMOGENEOUS MIXTURE
A solution is a homogeneous mixture. Its particles
are evenly spread out and blended thoroughly.

6. Components of a Solution
Solvent- usually a liquid that dissolves a solute.
Solute- a substance that is dissolved in a solid, gas,
or another liquid substance.

Ma. Rhodora Theodorosa S. Ma. Nieva, LPT

7. Solid Solution
Two or more solid substances
are transfeormed into liquid
form and the outcome of the
misxture is in solid form.

Ma. Rhodora Theodorosa S. Ma. Nieva, LPT

8. Liquid Solution
Both the solvent and the
solute are in liquid form.

Ma. Rhodora Theodorosa S. Ma. Nieva, LPT

9. Gaseous Solution
Both the solvent and the
solute are in their gaseous
state.

10. Concentration of Solution
The concentration of solution measures the quantity or
amount of solute dissolved in a given amount of solvent.
Concentrated – if the solution has a greater amount of solute
than solvent. The process of adding more solute to the solution
is called concentrating.
Diluted – if the solution is less concentrated or has greater
amount of solvent than solute. The process of adding more
solvent to a solution is called diluting.

Ma. Rhodora Theodorosa S. Ma. Nieva, LPT

11. Saturation of Solutions
The amount of solvent is
greater than the solute.
The solute is dissolved
and cannot be seen in
the solution.
If the maximum amount
os solute has been
successfully dissolved in
a given amount of
solvent.
The solution contains
more of the dissolved
solute than could be
dissolved by the solvent.

12. HETEROGENEOUS MIXTURE
A suspension is a heterogeneous mixture in which
the solute particles do not dissolve but get suspended
throughout the solvent after some time. Its particles are
seen easily because they are larger than the particles of the
solution.
Ex: Sand mixed in water

13. Suspensions
Prepared by:
Ma. Rhodora Theodorosa S. Ma. Nieva, LPT

14. Uses of Suspensions
1. Paint is used to decorate, protect and prolong the life of a material.
2. Flour is used to make a slurry.
3. Medicines are prescribed by doctors.

15. HETEROGENEOUS MIXTURE
A colloid is a heterogeneous mixture in which one
substance is dispersed throughout a second substance.
Prepared by:
Ma. Rhodora Theodorosa S. Ma. Nieva, LPT

16. Components of a Colloid
Dispersed phase- is the particulate component that is
present in relatively minor amount and evenly spread
throughout the dispersion medium.
Dispersion medium- is a substance or solution throughout
which the particulate is dispersed.
Prepared by:
Ma. Rhodora Theodorosa S. Ma. Nieva, LPT

17. Characteristics of Colloid
❑ Its particles never fully rest. They move along a zigzag course when
observed in microscopic scale. This is caused by the constant
collision between the particles and molecules in the dispersion
medium. This phenomenon is known as the Brownian movement.
Prepared by:
Ma. Rhodora Theodorosa S. Ma. Nieva, LPT

18. Characteristics of Colloid
❑ The particles are big enough to scatter light falling on
them in all direction. The scattering of light by colloidal
particles is called Tyndall effect.
