This document describes experiments on solubility conducted over 4 days: - Students observed how various solids like sugar, salt, and detergent dissolved in water. Temperature, particle size, and stirring affected solubility. Finer particles and higher temperatures increased dissolution rates. - Solutions were defined as homogeneous mixtures where a solute fully dissolves in a solvent, like sugar in water. Factors like amount of solvent and manner of stirring impacted solubility. - Through experiments, it was shown that increased temperature, finer particle size, and stirring facilitated faster dissolution of solutes like sugar and salt in water. The nature of the solute and amount of solvent also determined dissolution rates.

What happens when
solids are mixed with
water?

9. Let’s
EXPERIMENT!!!!

10. Activity 2.2
Mysterious Waters
MATERIALS:
Chocolate powder
Coffee powder
Creamer
Detergent soap
Glasses (8 pieces)
Powdered juice
Powdered milk
Spoon Sugar

11. PROCEDURES:
1. Get samples of sugar, coffee, powdered milk,
creamer, chocolate powder, powdered juice,
and detergent soap.
2. Prepare a spoon, 8 drinking glasses, and
water. Label the glasses 1 to 8.
3. Fill half of each glass with water.
4. Pour the sugar sample into glass 1. Pour the
coffee sample into glass 2. Do this with the rest
of the samples and glasses.
5. Mix the sample and water in each glass.
6. Describe what happens to the sample.

12. Guide Questions:
1. What solid materials
were dissolved in water?
2. What do you call this
solid materials?

15. When sugar is mixed with water, the
sugar seems to disappear into the water.
This is a process called dissolution. The
sugar did not really disappear. Its
molecules dissolved into the water that it
can no longer be seen. The same happens
with salt. You know that sugar and salt
are still there because you can taste it,
even though you cannot see it. The salt
and sugar were dissolved completely into
the water. This clear mixture is called
solution.

16. The solid material like soap,
powdered juice, powdered milk,
chocolate powder, and others which is
being dissolve is called solute. While
the dissolving medium (ex. water ) is
called solvent.

17. There are four types of solutions. All
these types are homogeneous.
1. Solid in liquid
A solid substance is dissolved in a
liquid substance. Examples are sugar in
water, salt in water, juice powder in
water, or coffee in water.

18. 2. Liquid in liquid
A liquid substance can also be
dissolved in another liquid and these
two substances can be mixed
thoroughly. Examples of these are
alcohol and water, wine and
soda water, concentrated fruit juice in
water, or liquid milk and water.

19. 3. Gas in liquid
Certain liquids contain gaseous substances.
Soft drinks appear as liquid, but they actually
contain carbon dioxide gas. This can be
observed when a bottle of soft drink is shaken
or opened, bubbles appear and gas is
released.
Oxygen is also present in water. Plants use
them during the food – making
process. There is also oxygen in the blood,

20. 4. Gas in gas
Air is a very good example of gas in a
gas solution. It is a mixture of several
gases– oxygen, nitrogen, carbon
dioxide, and others.
5. Solid in solid
Steel, basically a solution of carbon
atoms in a crystalline matrix of iron
atoms.
Alloys like bronze and many others.
Polymers containing plasticizers.

21. What is solution?
Answer in one
sentence.

22. Evaluation:
1. Give 2 more solids
that easily dissolve in
water.

Presentation

34. Solubility is the ability of a solute to dissolve
in a solvent at a given temperature. Usually
the higher the temperature, the faster a
solute can be dissolved in a solvent. The
nature of solute and the amount of solvent
also determine how fast the solute dissolves
in a solvent. The size of the particles affects
the dissolving process. The finer the
particles are, the faster the solute dissolves.
The manner of stirring is also a factor to
dissolve a solute in a solvent.

35. Evaluation
Match the factors affecting the solubility of the solute in a solvent in column A to
the situations in column B.
Column A
1. _____ Amount of solvent
2. _____Manner of stirring
3. _____ Size of the solute particles
4. _____ Temperature of the solvent
5. _____ Immiscibility
Column B
A. Dissolving coffee with coffee mate in a water using a spoon or a stick.
B. Dissolving three tablespoons of milk powder in a glass of warm water.
C. Mix baby oil with water. They do not mix completely with one another.
D. Some grains of sugar settle at the bottom of the glass of the water while black coffee has
already dissolved.
E. A sachet of fruit juice powder dissolves in a half glass of water slower than in a pitcher of
water.
