Solubility Curves

Front

What is a solubility curve?

Back

A graphical representation showing the relationship between the solubility of a substance and temperature.

Front

What does it mean for a solution to be saturated?

Back

A saturated solution 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 contains less solute than can be dissolved at a given temperature.

Front

Define a supersaturated solution.

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature, often achieved by heating the solution and then cooling it.

Front

What factors affect solubility?

Back

Temperature, pressure (for gases), and the nature of the solute and solvent.

Front

How does temperature affect the solubility of solids in liquids?

Back

Generally, the solubility of solids in liquids increases with an increase in temperature.

Front

How does temperature affect the solubility of gases in liquids?

Back

The solubility of gases in liquids typically decreases as temperature increases.
