Solutions" refers to two main concepts: A solution in chemistry is a homogeneous mixture of two or more substances, like salt dissolved in water, where one substance (the solute) is dissolved uniformly in another (the solvent). A solution in a general sense is a means of solving a problem or dealing with a difficult situation, providing an answer or explanation.

LEARNING OBJECTIVES
Identify the
components of
solutions
describe the properties
of solution
classify the different
types of solution

3. WHAT IS A
SOLUTION?
A solution is a mixture formed
when a solute dissolves in a
solvent.

4. SOLUTE SOLVENT SOLUTION

5. SOLUTE
The solute is the
substance that is being
dissolved in a solution

6. SOLVENT
The solvent is the
substance that dissolves
the solute. Water is known
as the universal solvent.

7. DISSOLUTION
Dissolution is the process by which is solution is formed.

8. Solutions around us are classified according to their
solvent phases; thus, a solution may be liquid, gaseous or
solid.
TYPES OF SOLUTION

9. A liquid solution results
when a gas, liquid or solid
dissolves in a liquid solvent.
LIQUID
SOLUTIONS
For example:

10. A solution does not always
have to be liquid, the air
you breathe is a solution of
gases.
GASEOUS
SOLUTIONS

11. A solid solution forms when a
liquid and a solid, or two or more
solid substances are melted,
mixed and cooled. Solid
solutions containing metals are
called alloys.
SOLID
SOLUTIONS
A metal alloy is a solution of a
solid dissolved an another solid.

12. Write S if it is a solution then identify the type of
solution, and write N if it is not a solution.
FOR EXAMPLE:
BRONZE - SOLUTION SOLID SOLUTION

13. Write S if it is a solution then identify the type of
solution, and write N if it is not a solution.
