Solubility Graphs

Front

What is solubility?

Back

Solubility is the maximum amount of a substance (solute) that can dissolve in a given amount of solvent at a specific temperature and pressure.

Front

What is a solubility graph?

Back

A solubility graph is a visual representation that shows how the solubility of a substance changes with temperature.

Front

What does a saturated solution mean?

Back

A saturated solution is one in which the maximum amount of solute has been dissolved in the solvent 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, often achieved by changing conditions.

Front

How does temperature affect solubility of most solids?

Back

For most solids, solubility increases with an increase in temperature.

Front

How does temperature affect the solubility of gases?

Back

For gases, solubility typically decreases as temperature increases.
