A solution is formed when a solute dissolves completely and uniformly throughout a solvent. There are three main types of solutions: gaseous solutions where gases are dissolved in other gases; liquid solutions where solids, liquids or gases are dissolved in liquids; and solid solutions where solids are dissolved in other solids. The solubility of a solution depends on the temperature - as temperature increases, more solute can typically dissolve.

2. A solution is formed
when a solute
dissolves in a solvent
to form a single
phase that appears
uniform throughout.

3. • A solution is clear.
• In a solution, the particles are too small that they
cannot be seen by unaided/naked eye.
• The solute from the solution cannot be separated by
filtration.
• The solution does not allow beam of light to scatter.
• A solution is a homogenous mixture
• A solution is stable.
• As temperature increases, the solubility (of solids)
increases.
• All solutions have a solvent and at least one solute

4. • There is a limit to how much solute will dissolve in a
given volume of solvent at a given temperature.
Saturated solution = when that limit has been
reached & no more solid can dissolve.
• White solids become invisible when dissolved in clear
solvents.
• Non-white solids give their color to their solvents.
• You can separate dissolved solutes from solution by
evaporating away the liquid solvent.
• In some solutions, volume decreases as the solute
dissolves.

5. • Mass is conserved when solutes dissolve in solvents.
• As you increase the amount of solvent, the amount
of solute that can dissolve will also increase at the
same rate.
• A solution has a constant density throughout.
• Solutions are transparent (light can travel through
them without being "blurred")

6. Gaseous Solution- includes gases or vapors dissolved in one
another. Two or more gases can form a solution. Air is an
example of a gaseous solution. When dry is made up of
oxygen gas dissolved in nitrogen gas.
Liquid Solution-contain a liquid solvent in which gas, liquid,
or solid is dissolved. Water is the most common liquid
solution. Many things can be dissolved in it. Table salt is an
example of a solid dissolved in a liquid. A liquid and a gas
can also be dissolved in a liquid solution.
 Solid Solution-is a mixture of solids spread equally
throughout one another. Metal is an example of a solid
solution at room temperature.

7. Solubility is the maximum amount of solute
that can dissolve in a given amount of solvent
at a certain temperature.
 Saturated – maximum amount of solute
dissolved by a given amount of solvent.
 Unsaturated – when it contains less
solute than the maximum amount it can
dissolve at a given temperature.

8.  The particles of solute are the size of individual
small molecules or individual small ions. One
nanometer is about the maximum diameter for a
solute particle.
 The mixture does not separate on standing. In a
gravity environment the solution will come apart
due to any difference in density of the materials in
the solution.
 The mixture does not separate by common fiber
filter. The entire solution will pass through the filter.
