Solubility Curves

Front

What is a solubility curve?

Back

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

Front

Define unsaturated solution.

Back

A solution that contains less solute than the maximum amount that can dissolve at a given temperature.

Front

Define saturated solution.

Back

A solution that contains the maximum amount of solute that can dissolve at a given temperature.

Front

Define supersaturated solution.

Back

A solution that contains more solute than the maximum amount that can dissolve at a given temperature, usually achieved by heating.

Front

What happens to the solubility of most solids as temperature increases?

Back

The solubility of most solids increases with an increase in temperature.

Back

65 grams per 100 grams of water.

Front

What type of solution is formed when 30 grams of KCl is dissolved in 100 grams of water at 10°C?

Back

Saturated solution.

Front

What type of solution is formed when 70 grams of CaCl2 is dissolved in 100 grams of water at 30°C?

Back

What is the significance of a solubility curve in chemistry?

Back

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