Solutions and Solubility Curves

Front

What is a solution?

Back

A homogeneous mixture of two or more substances where one substance (solute) is dissolved in another (solvent). Example: Salt water.

Front

What is a solubility curve?

Back

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

Front

What is a saturated solution?

Back

A solution that contains the maximum amount of solute that can be dissolved 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 be dissolved at a given temperature.

Front

What happens to solubility as temperature increases for most solids?

Back

Solubility typically increases as temperature increases.

Front

What happens to solubility as temperature increases for gases?

Back

Solubility typically decreases as temperature increases.

Front

What is a heterogeneous mixture?

Back

A mixture that consists of visibly different substances or phases. Example: Salad.

Front

What is a homogeneous mixture?

Back

A mixture that has a uniform composition throughout. Example: Air.

Front

What is the effect of heating a solution on solute dissolution?

Back

Heating a solution generally allows more solute to dissolve.
