What is a solubility curve?

Back

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

Front

Define saturated solution.

Back

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

Front

What is an unsaturated solution?

Back

A solution that contains less solute than it has the capacity to dissolve at a given temperature.

Front

What is a supersaturated solution?

Back

A solution that contains more solute than it can theoretically hold at a given temperature.

Front

How does temperature affect solubility?

Back

Generally, for most solids, solubility increases with temperature, while for gases, it decreases.

Front

What is the solubility of KCl in 100 g of water at 50 ºC?

Back

Approximately 50 grams.

Front

What is the solubility of CaCl2 in 100 g of water at 17 ºC?

Back

Approximately 70 grams.

Front

What happens when a saturated solution is cooled?

Back

Some solute may crystallize out of the solution.

Front

Which solute is least soluble at 90 ºC: SO2, KClO3, KI, or HCl?

Back

SO2.

Front

What is the significance of a solubility curve in chemistry?

Back

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