Solubility Curves

Front

What is a solubility curve?

Back

A graphical representation showing 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 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, the solubility of solids increases with temperature, while the solubility of gases decreases.

Front

What is the solubility of KNO3 at 40ºC?

Back

Approximately 100g in 100g of water.

Front

What is the solubility of NaCl at 60ºC?

Back

Approximately 40g in 100g of water.

Front

How much NaBr is saturated at 70 degrees?

Back

120 grams.

Front

What is the solubility of K2Cr2O7 at 95ºC?

Back

75 grams in 100g of water.

Front

What does it mean if two solubility curves intersect?

Back

It indicates that the solubility of the two substances is equal at that temperature.
