Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent at a given temperature and pressure.

Front

What is a solute?

Back

A solute is the substance that is dissolved in a solution.

Front

What is a solvent?

Back

A solvent is the substance in which the solute is dissolved to form a solution.

Front

What is a saturated solution?

Back

A saturated solution is one that contains the maximum amount of solute that can dissolve at a given temperature.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute at a given temperature.

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature.

Front

How does temperature affect solubility?

Back

Generally, for most solids, solubility increases with temperature, while for gases, solubility decreases with increasing temperature.
