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 the difference between a saturated and an unsaturated solution?

Back

A saturated solution has dissolved all the solute it can at a given temperature, while an unsaturated solution can still dissolve more solute.

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 and then cooling it.

Front

How does temperature affect solubility?

Back

Generally, for most solids, solubility increases with temperature, while for gases, solubility decreases with increasing temperature.

Front

What is the solubility of KNO3 at 40 degrees Celsius?

Back

65 grams per 100 grams of water.

Front

What is the solubility of K2Cr2O7 at 90 degrees Celsius?

Back

70 grams per 100 grams of water.

Front

Which substance is most soluble at 0 degrees Celsius?

Back

NaNO3 is the most soluble at 0 degrees Celsius.

Front

What happens to the solubility of NaCl as temperature increases?

Back

The solubility of NaCl generally increases as temperature increases.

Front

What is the solubility of C12H22O11 at 40 degrees Celsius?

Back

240 grams per 100 grams of water.
