Types of Solutions

A solution can be classified according to the amount of solute and solvent it contains. It can be diluted, concentrated, or saturated.

A diluted solution is formed when a small amount of solute is dissolved in a solvent. A teaspoon of powdered juice dissolved in a glass of water is an example of a diluted solution.

A concentrated solution is formed when a large amount of solute is mixed with a solvent. When three tablespoons of powdered juice are dissolved in a glass of water, a concentrated solution is formed.

A saturated solution is formed when there is much more solute in the solution than the solvent can dissolve at a specific temperature and pressure. When the maximum amount of solute has already been dissolved, the solvent can no longer dissolve the excess solute. Thus, some solid particles settle at the bottom of the container. For example, when a large amount of powdered juice is mixed in a glass of water and no more powdered juice can be added and dissolved, a saturated solution is formed.
