Solubility Curves

Front

What is a solubility curve?

Back

A graphical representation showing the relationship between 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 can be dissolved at a given temperature.

Front

What is a supersaturated solution?

Back

A solution that contains more solute than can be dissolved at a given temperature, often achieved by heating.

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 50 ºC?

Back

Approximately 42 grams per 100 grams of water.

Front

What is the solubility of C12H22O11 at 40 ºC?

Back

240 grams per 100 grams of water.

Front

At what temperature can you fully dissolve 60g of KNO3?

Back

37 ºC.

Front

What is the solubility of NaBr at 70 ºC?

Back

120 grams per 100 grams of water.

Front

What happens when a saturated solution is cooled?

Back

Excess solute may precipitate out of the solution.
