Solubility Curves

Front

What is a saturated solution?

Back

A saturated solution is one in which the maximum amount of solute has been dissolved in a solvent at a given temperature.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that contains less solute than can be dissolved at a given temperature.

Front

What is a supersaturated solution?

Back

A supersaturated solution is one that contains more solute than can normally be dissolved at a given temperature.

Front

What does solubility refer to?

Back

Solubility refers to the ability of a substance (solute) to dissolve in a solvent at a specific temperature and pressure.

Front

How does temperature affect solubility?

Back

Generally, for most solids, solubility increases with an increase in temperature, while for gases, solubility decreases with an increase in temperature.

Front

What is the solubility of KBr at 55°C?

Back

At 55°C, the solubility of KBr is approximately equal to that of KNO3.

Front

What is the solubility of KNO3 at 40°C?

Back

The solubility of KNO3 at 40°C is 65 grams per 100 grams of water.

Front

What is the solubility of C12H22O11 at 40°C?

Back

The solubility of C12H22O11 (sucrose) at 40°C is 240 grams per 100 grams of water.

Front

What is the significance of a solubility curve?

Back

A solubility curve graphically represents the relationship between solubility and temperature for a given solute.

Front

How can you determine if a solution is saturated?

Back

A solution is saturated if additional solute does not dissolve and settles at the bottom.
