The maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.

Front

What factors affect the solubility of a substance?

Back

Temperature, pressure, and the nature of the solute and solvent.

Front

What is the difference between a saturated and unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve, while an unsaturated solution can still dissolve more solute.

Front

Back

Supersaturated solution.

Front

What is the role of temperature in the solubility of solids in liquids?

Back

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