Solubility Curve

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 if a solution is saturated?

Back

A solution that has dissolved the maximum amount of solute 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 dissolved solute than it can theoretically hold at a given temperature.

Front

Which solute does not increase in solubility with temperature?

Back

Ammonia (NH3) is an example of a solute that does not increase in solubility as temperature rises.

Front

What is the solvent in a solution?

Back

The part of the mixture that dissolves the solute; usually the component present in the largest amount.

Front

What is the solute in a solution?

Back

The substance that is dissolved in the solvent.

Front

How does temperature affect the solubility of most solids?

Back

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

Front

How does temperature affect the solubility of gases?

Back

The solubility of gases typically decreases as the temperature increases.

What is the solubility of KClO3 at 80 ºC?

Back

At 80 ºC, KClO3 is unsaturated when 20 grams are dissolved in 100 grams of water.
