The document discusses the solubility process and factors that affect the rate of dissolving solids in liquids. It explains that solvation is the process where solute particles are surrounded by solvent particles to form a solution. The rate of dissolving can be increased by agitation, surface area, and temperature. Solubility depends on the nature of the solute and solvent and is generally affected by temperature and pressure. The solubility of gases decreases with increasing temperature according to Henry's Law.

2. The SolvaTion ProceSS
 Attractive forces exist among the particles of
all substances
 London Dispersion
 Dipole-dipole
 Hydrogen bonding
 If the attractive forces between the solute and
the solvent are greater than the attractive
forces holding the solute particles together, the
solute dissolves in the solvent

3. Solvation is the process of surrounding
solute particles with solvent particles to
form a solution.
Solvation in water is called hydration.
For ionic compounds that dissolve in
water, the attraction between dipoles of
a water molecule and the ions of a
crystal are greater than the attraction
among ions of a crystal.

4. Factors that aFFect rate oF
dissolving oF solid in liquid
 1. Agitation
 Stirring or shaking moves dissolved particles away from
the contact surfaces more quickly and allows new
collisions to occur.
 This is why you stir your tea after you put sugar in it.
 2. Surface area
 Breaking the solute into small pieces increases surface
area and allows more collisions to occur.
 This is why you use granulated sugar instead of sugar
cubes

5. Factors that aFFect rate oF
dissolving oF solid in liquid
3. Temperature
As temperature increases, rate of
solvation increases.  Particles are
moving faster.
This is why sugar dissolves faster in
hot tea than in iced tea.

6. solubility
Solubility depends on the nature
of the solute and solvent.
Solubility is affected by
increasing the temperature of the
solvent because the kinetic energy
of the particles increases.

7. Solubility of SolidS in liquidS
Generally increases with
an increase in
temperature (some
exceptions)
Not affected by pressure

8. Solubility of gaSeS in liquidS
Increases with an increase in
pressure (Henry’s Law)
This is how carbonated
beverages are made and why
they go flat if left open

9. Solubility of gaSeS in liquidS
How is the solubility of gases
affected by temperature?
Solubility of gases decreases with an
increase in temperature
This is why soda at room temperature
goes flat faster than soda in the
refrigerator
