Interpreting Solubility Curves

Front

What is a solubility curve?

Back

A graphical representation showing the amount of solute that can dissolve in a solvent at various temperatures.

Front

What does it mean if a solution is saturated?

Back

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

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute at a given temperature.

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature, often achieved by heating the solution.

Front

How does temperature affect solubility?

Back

Generally, solubility of solids increases with temperature, while the solubility of gases decreases.

Front

What is the solubility of KNO3 at 40 degrees Celsius?

Back

65 grams per 100 grams of water.

Front

What happens to solubility when a solution is cooled?

Back

If a supersaturated solution is cooled, it may precipitate some solute as it can no longer hold the excess solute.

Front

How can you determine if a solution is saturated?

Back

If additional solute does not dissolve and settles at the bottom, the solution is saturated.

Front

What is the solubility of K2Cr2O7 at 95 degrees Celsius?

Back

75 grams per 100 grams of water.

Front

What is the significance of a solubility curve?

Back

It helps predict how much solute can dissolve at different temperatures, aiding in solution preparation.
