Solubility Curves

Front

What is a solubility curve?

Back

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

Front

What does it mean for a solution to be 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.

Front

How does temperature affect solubility?

Back

Generally, solubility of solids increases with temperature, while the solubility of gases decreases.

Front

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 80 grams per 100 grams of water.

Front

What happens when a saturated solution is cooled?

Back

Some solute may crystallize out of the solution as it cools.

Front

What is the significance of a solubility curve?

Back

It helps predict how much solute can dissolve at different temperatures.

Front

What is the solubility of Ce2(SO4)3 at 80°C?

Back

Approximately 2 grams per 100 grams of water.
