Solubility Curve

Front

What is a solubility curve?

Back

A graphical representation showing the relationship between the solubility of a substance and temperature.

Front

What does it mean if a solution is unsaturated?

Back

It means that more solute can still be dissolved in the solvent at a given temperature.

Front

What does it mean if a solution is saturated?

Back

It means that the maximum amount of solute has been dissolved in the solvent at a given temperature.

Front

What does it mean if a solution is supersaturated?

Back

It means that the solution contains more solute than it can normally hold at a given temperature, often achieved by heating.

Front

How does temperature affect the solubility of most solids in water?

Back

Generally, the solubility of most solids increases as the temperature of the water increases.

Front

What is the solubility of KNO3 at 80 ºC?

Back

Approximately 120 grams per 100 grams of water.

Front

What is the solubility of NaCl at room temperature?

Back

About 36 grams per 100 grams of water.

Front

Which solute's solubility decreases with an increase in temperature?

Back

NH3 (ammonia) is an example of a solute whose solubility decreases as temperature rises.

Front

What is the solubility of CaCl2 at 17 ºC?

Back

Approximately 70 grams per 100 grams of water.

Front

What happens to the solubility of gases in liquids as temperature increases?

Back

The solubility of gases generally decreases as temperature increases.
