Solubility Curves 10Q

Front

What is a saturated solution?

Back

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

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that contains less solute than the maximum amount that can be dissolved at a given temperature.

Front

What is a supersaturated solution?

Back

A supersaturated solution is one that contains more solute than can normally be dissolved at a given temperature, often achieved by heating the solution and then cooling it.

Front

How does temperature affect solubility?

Back

Generally, for most solids, solubility increases with temperature, meaning more solute can be dissolved in a solvent at higher temperatures.

Front

What is the solubility curve?

Back

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

Front

What does it mean if a solution is at the solubility limit?

Back

If a solution is at the solubility limit, it means that no more solute can be dissolved in the solvent at that temperature.

Front

What happens when a saturated solution is cooled?

Back

When a saturated solution is cooled, some of the solute may crystallize out of the solution as it can no longer remain dissolved.

Front

What is the solubility of NaNO3 at 40ºC?

Back

At 40ºC, the solubility of NaNO3 is approximately 80g per 100g of water.

Front

What is the solubility of NaCl at 70ºC?

Back

At 70ºC, the solubility of NaCl is approximately 40g per 100g of water.

Front

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

Back

The solubility product constant (Ksp) is a measure of the solubility of a compound in a saturated solution and is used to predict the solubility of ionic compounds.
