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

How does temperature affect solubility?

Back

Generally, increasing temperature increases the solubility of solids in liquids, while the effect on gases can vary.
