The document discusses factors that affect solubility, including temperature, pressure, and the nature of the solute and solvent. It notes that solubility generally increases with temperature for solids dissolving in liquids. For gases, solubility increases with increasing pressure based on Henry's law. The conclusion summarizes that the solubility of most substances depends on temperature and pressure, with solids and liquids increasing in solubility at higher temperatures and gases increasing with greater pressures.

3. INTRODUCTION TO SOLUBILITY
Solubility is the ability of a substance to dissolve in a solvent. It
is affected by a variety of factors, including temperature,
pressure, and the concentration of the solute and solvent.
In order to understand solubility, it is important to understand the
concept of solvation, which is the process of one substance
dissolving in another.

4. NATURE OF SOLUTE
AND SOLVENT
A solute is a substance that can be dissolved
by a solvent to create a solution. A solute can
come in many forms. It can be gas, liquid, or
solid. The solvent, or substance that
dissolves the solute, breaks the solute apart
and distributes the solute molecules equally.

5. TEMPERATURE
Solubility increases on increase in temperature in case of solids in liquids. The increase
in kinetic energy that comes with higher temperature allows the solvent molecules to
more effectively break apart the solute molecules that are held together by
intermolecular attractions.

6. THE EFFECT OF TEMPERATURE ON
SOLUBILITY
7/1/20XX 6
If a substance is soluble it will dissolve in a given amount of liquid, called the
‘solvent’.
In general, solids become more soluble as the temperature increases. This
is why sugar dissolves better in hot water than in cold water.

7. PRESSURE
7/1/20XX 7
External pressure has very little effect on the solubility of liquids and solids. In contrast,
the solubility of gases increases as the partial pressure of the gas above a solution
increases.
Carbonated beverages provide the best example of this phenomena. All carbonated
beverages are bottled under pressure to increase the carbon dioxide dissolved in
solution. When the bottle is opened, the pressure above the solution decreases. As a
result, the solution effervesces and some of the carbon dioxide bubbles off.

8. THE EFFECT OF TEMPERATURE ON
SOLUBILITY
7/1/20XX 8
Liquids and solids exhibit practically no change of solubility with changes in pressure. Gases as
might be expected, increase in solubility with an increase in pressure. Henry's Law states that:
The solubility of a gas in a liquid is directly proportional to the pressure of that gas above the
surface of the solution.
If the pressure is increased, the gas molecules are "forced" into the solution since this will best
relieve the pressure that has been applied. The number of gas molecules is decreased. The
number of gas molecules dissolved in solution has increased.

10. CONCLUSION
7/1/20XX 10
The solubility of most substances depends
strongly on the temperature and, in the case of
gases, on the pressure. The solubility of most
solid or liquid solutes increases with increasing
temperature.
The components of a mixture can often be
separated using fractional crystallization, which
separates compounds according to their
solubilities. The solubility of a gas decreases
with increasing temperature. Henry’s law
describes the relationship between the pressure
and the solubility of a gas.
