Solubility Curves

Front

What is a solubility curve?

Back

A graphical representation showing the relationship between the solubility of a substance and temperature.

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

Front

Define 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 C12H22O11 at 40 degrees Celsius?

Back

240 grams per 100 grams of water.

Front

What is the solubility of HCl at 45 degrees Celsius?

Back

At 45 degrees Celsius, at least 60 grams of HCl can dissolve.

Front

At what temperature do KBr and KNO3 have the same solubility?

Back

55 degrees Celsius.

Front

What is the significance of a solubility graph?

Back

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

Front

What happens to a saturated solution if more solute is added?

Back

The excess solute will not dissolve and will remain undissolved at the bottom of the container.
