What is a solubility curve?

Back

A graphical representation showing how the solubility of a substance varies with temperature.

Front

Define solubility.

Back

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

Front

What is a saturated solution?

Back

A solution in which no more solute can dissolve at a given temperature.

Front

What is an unsaturated solution?

Back

A solution that can still dissolve more solute at a given temperature.

Front

What is a supersaturated solution?

Back

A solution that contains more solute than can normally dissolve at a given temperature.
