3. OBJECTIVES
1.Describe unsaturated, saturated, and
supersaturated solutions.
2.Determine how much solid solute
dissolves in each volume of water.
3.Describe the appearance of
unsaturated, saturated, and
supersaturated solutions.
13. QUESTIONS
A.Based on the activity, answer the following questions:
1.) What is the appearance of the salt solution in 3 set-
ups?
2.) How many grams of powdered juice added to the
solution until it is no longer dissolves?
3.) Is there a limit to the amount of salt you can dissolve
in each amount of water?
14. EXPLORE
B. BASED ON THE ACTIVITY, DESCRIBE THE APPEARANCE AND CLASSIFY WHETHER THE
TYPE OF SOLUTION DESCRIBED AS SATURATED, UNSATURATED, OR SUPERSATURATED.
NOTE: THE 35 GRAMS OF TABLE SALT WILL FORM SATURATED SOLUTION IN 100 ML OF WATER.

16. TYPES OF SOLUTION
UNSATURATED SOLUTION
A solution that contains less
solute from the maximum amount it
can dissolve at a given temperature.
17. TYPES OF SOLUTION
SATURATED SOLUTION
A solution that contains the
maximum amount of solute
dissolved by a given amount of
solvent .
18. TYPES OF SOLUTION
SUPERSATURATED SOLUTION
A solution that contains the
maximum amount of solute dissolved
by a given amount of solvent .
If you add more solute to the solvent
and there is a presence of an excess
solute which can no longer dissolve.
19. ACTIVITY
Draw and describe the appearance of the solution
if it is saturated, unsaturated, or supersaturated.
Color it and label what type of solution in each
container.
20. QUESTIONS
1.) Which type of solution has the least
amount of solute dissolved?
2.) Which type of solution has the maximum
amount of solute that can be dissolved?
3.) Which type solution has more amount of
solute dissolved?
4.) Describe the appearance of the solutions.

in a cup of hot coffee or cocoa powder in
your hot cocoa drink?

5. Which of the following describe the appearance of
unsaturated solution.
a. Unsaturated solution has lighter color
than saturated solution.
