Solubility Curves

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 saturated?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute at a given temperature.

Front

Define a supersaturated solution.

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature, often achieved by heating.

Front

What factors affect solubility?

Back

Temperature, pressure (for gases), and the nature of the solute and solvent.

Front

How does temperature affect the solubility of solids in liquids?

Back

Generally, the solubility of solids increases with an increase in temperature.

Front

How does temperature affect the solubility of gases in liquids?

Back

The solubility of gases typically decreases as temperature increases.

What is the solubility of KCl at 10°C?

Back

Approximately 30 grams per 100 grams of water.

Front

What is the solubility of NaNO3 at 40°C?

Back

Approximately 60 grams per 100 grams of water.

Front

What is the solubility of CaCl2 at 30°C?

Back

Approximately 70 grams per 100 grams of water.
