Solubility Curves

Front

What is a solubility curve?

Back

A graph that shows the relationship between the solubility of a substance and temperature, indicating how much solute can dissolve in a solvent at various temperatures.

Front

What does it mean for a solution to be saturated?

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 contains less solute than can be dissolved 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 heating the solution and then cooling it.

Front

How does temperature affect solubility?

Back

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