SATURATED
AND
UNSATURATED SOLUTION
WHAT IS A SOLUTION?
Solution is a homogenous
mixture of two components:
solute and solvent.
WHAT IS THE DIFFERENCE
BETWEEN SOLUTE AND
SOLVENT?
The solute is the component
that is present in the minority
and the solvent is the
component that is present in
the majority.
A solution in which solutes dissolve is referred
to as an unsaturated solution. A solution is
made up of two types of particles: solutes and
solvents. Water is commonly used as a solvent
(which is one of the reasons why water is also
called the universal solvent).
EXAMPLE:
A solution of sugar in water
A solution of salt in water
A solution of air in water
A solution of oxygen in nitrogen
WHAT ARE THE TYPES OF
SOLUTIONS?
SATURATED
UNSATURATED
SUPERSATURATED
SATURATED
A saturated solution is a chemical
solution that contains the largest
quantity of solute contained in the
solvent at the given temperature.
The solute cannot be dissolved
anymore in a saturated solution at
that temperature.
SATURATED
The saturation point of any liquid
is determined by the type of the
material and the temperature. A
saturated solution is one in which
the quantity of dissolved solute
equals the saturation point of the
solvent. A solvent can dissolve
some particular types of solutes
in it.
SATURATED SOLUTION EXAMPLE
•Soil is a saturated mixture consisting of nitrogen.
On attaining the saturation point, the excess
nitrogen is emitted out into the air in the form of
gas.
•Beverages, such as cold drinks are saturated
solutions of dissolved CO2 in water.
•Protein drinks which is a saturated solution of
protein powder in milk or any other solvent
UNSATURATED
•The solution in which more solute can
be added at a given temperature is
called unsaturated solution.
• Unsaturated solutions have the ability
to dissolve additional solute until they
achieve saturation. Solutes will no
longer dissolve in the solvent after
reaching the saturation threshold,
resulting in unsaturated solutions.
UNSATURATED
As a result, all solutions are considered to
be largely unsaturated in nature before
being
transformed
into
saturated
solutions by adding solute to them. The
amount of solute that is contained in
lesser amounts than the maximum value,
that is before the solution reaches the
saturation level is called an unsaturated
solution. An unsaturated solution is
basically a chemical solution that has a
solute concentration lesser than its
corresponding equilibrium solubility.
UNSATURATED SOLUTION
EXAMPLES
•Salt or sugar dissolved in the water
below the saturation point.
•Air or mist.
•Iced coffee.
•Vinegar is the acetic acid solution in
water
Difference between Saturated and
Unsaturated Solution
The key differences between Saturated
and Unsaturated solutions are as
follows:
How to find whether the given Solution is
Saturated or Unsaturated?
Step 1: Add a small amount of solute to the
solution.
Step 2: Stir the solution thoroughly.
Step 3: If the solute dissolves, the solution is
unsaturated.
Step 4: If the solute does not dissolve, the
solution is saturated
