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

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

How do 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

What is the significance of the solubility product constant (Ksp)?

Back

Ksp is a constant that indicates the solubility of a compound in a saturated solution at a specific temperature.

Front

How can you identify a supersaturated solution?

Back

A supersaturated solution can often be identified by the presence of undissolved solute or by crystallization when disturbed.

Front

What is the solubility of NaNO3 at 40ºC according to the solubility curve?

Back

Approximately 60g per 100g of water.
