11. Halo-halo is an example of a mixture.
A mixture is a substance made by mixing
other substances together. When two or
more elements or compounds mix together,
not necessarily in a definite ratio and do not
interact chemically, then the resulting
substance is known as a mixture.

12. Halo-halo orange juice
Compare the two mixtures

13. What have you observe to the mixture of
Halo-halo?

14. What have you observe to the mixture of
orange juice?

15. Types of Mixture
There are two types of mixtures.
One is homogenous mixture
which contains substances that are evenly mixed and is
uniform throughout in terms of physical appearance.
The other one is heterogeneous mixture which
contains component substances that are usually easy to
distinguish.

16. Homogeneous mixtures
Also called uniform mixture because it has uniform
composition where the substances are evenly mixed. They are
also called solution. In its component, the substance that
dissolves or seems to disappear is called a solute while the
one that dissolves is the solvent.
Homo means same

17. Types of Homogenous Mixtures
There are three types of homogenous mixtures.
These are:
(1)solid homogenous mixtures,
Examples: bronze, steel
(2)liquid homogenous mixtures
Examples: vinegar and water
(3) gaseous homogenous mixtures.
Examples: air

18. heterogeneous or non-uniform mixtures
components have different compositions and are
not uniform throughout in terms of the appearance making
them easy to identify. They are also called non-uniform
mixtures.
Hetero means different

together.
________2. It contains substances that are evenly mixed and
is uniform throughout in terms of physical appearance.
________3. It contains component substances that are usually
easy to distinguish
________4. It is also called uniform mixture.
________5. It is also called non-uniform mixture.

21. To summarize on the characteristics of homogenous and
heterogenous mixtures, study the chart given below

22. SOLUTE- Being dissolved
SOLVENT- dissolving agent like water
SOLUBLE- substances that can be dissolved.
INSOLUBLE- substances that cannot be dissolved.

23. Solubility is the maximum amount of a
solute substance that will dissolve in a
given amount of solvent at a specific
temperature. There are different
factors that affect solubility:

24. FACTORS AFFECTING THE SOLUBILITY
1. Nature of Solute- It tells about whether
the solvent is in liquid, solid or in gas
form.
2. Manner of Stirring- It depends on how
fast or slow mixture was stirred.
3. Size of the Solute- It tells whether the
solute is soft or hard, powder or a whole
piece.

25. FACTORS AFFECTING THE SOLUBILITY
4. Temperature- It tells how
hot or cold is the solvent
mixed in a mixture.
5. Amount of solvent- It tells
how much solvent is mixed in
a mixture.

26. Solutions and
Their
Characteristics

28. A solution is a
homogeneous
mixture of one or
more solutes
dissolved
in a solvent. There
are many kinds of
solutions. It exists in
any phase. The
solution particles
cannot be seen by
our naked eye.
