A solution is a homogeneous mixture composed of only one phase. In such mixture, there is a solute and a solvent.
An example of a solution are different kinds of chemicals. |
A solute is a substance that is being dissolved while the solvent is the one that does the dissolving.
Characteristics of a Solution:
A diagram showing the properties of a solute and a solvent. |
- A solution is a homogeneous mixture.
- The particles of solute in solution cannot be seen by naked eye.
- The solution does not allow beam of light to scatter.
- A solution is stable.
- The solute from the solution cannot be separated by filtration (or mechanically).
Colligative properties are properties of solutions that depend upon the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the type of chemical species present.
Colligative properties include:
- Relative lowering of vapor pressure
- Elevation of boiling point
- Depression of freezing point
- Osmotic pressure.
