1. The World Of Solutions 3

2. PROPERTIES Particles spread evenly throughout the solution
Uniform composition (components are all in the same state)
Particles do not settle
Particles cannot be distinguished
by the eye

3. Components of a Solution
is made up of a
and
A solute dissolves in the
solvent.
A SOLVEnt does the dissolving of the solute (making it “disappear”), resulting in a uniform composition.
If a solute can dissolve, it is said to be
soluble and forms a solution.
The solvent is usually in the same state as the solution.
A solute can be a solid, a liquid, or a gas.
A solvent can be a solid, a liquid, or a gas.

4. Diluted: Concentrated: Saturated:
It measures how much solute is in the solvent.
Diluted:
Concentrated:
Saturated:
low concentration of solute present in the solution
high concentration of solute present in the solution
cannot dissolve any more solute

5. What makes up this mixture?
Look at the experiment results and determine if a solution has been made. If it has, then decide which substance is the solvent and which substance is the solute.
