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 saturated solution.

Back

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

Front

Define unsaturated solution.

Back

A solution that contains less solute than can be dissolved at a given temperature.

Front

Define supersaturated solution.

Back

A solution that contains more solute than can be dissolved 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.

Front

What happens to the solubility of gases as temperature increases?

Back

The solubility of gases generally decreases as temperature increases.

Front

What is the significance of a solubility curve?

Back

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

Front

How can you determine if a solution is saturated using a solubility curve?

Back

If the amount of solute is equal to the value on the curve at a specific temperature, the solution is saturated.

Front

How can you determine if a solution is unsaturated using a solubility curve?

Back

If the amount of solute is less than the value on the curve at a specific temperature, the solution is unsaturated.

Front

How can you determine if a solution is supersaturated using a solubility curve?

Back

If the amount of solute is greater than the value on the curve at a specific temperature, the solution is supersaturated.
