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.

Front

How does temperature affect solubility?

Back

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

Front

What is the solubility of NaBr at 70ºC?

Back

At 70ºC, the solubility of NaBr is approximately 120g per 100g of water.

Front

What is the solubility of NaNO3 at 73ºC?

Back

At 73ºC, the solubility of NaNO3 is approximately 140g per 100g of water.

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 C12H22O11 (sucrose) at 40ºC?

Back

The solubility of sucrose at 40ºC is approximately 240g per 100g of water.

Front

What happens to the solubility of gases when temperature increases?

Back

The solubility of gases typically decreases as temperature increases.
