Solubility Curves

Front

What is a solubility curve?

Back

A graph that shows the relationship between the solubility of a substance and temperature.

Front

What does saturation mean in the context of solubility?

Back

Saturation occurs when a solution can no longer dissolve additional solute at a given temperature.

Front

How does temperature affect solubility?

Back

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