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 for a solution to be saturated?

Back

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

Front

How does temperature affect the solubility of most solids?

Back

For most solids, solubility increases as temperature rises.

Front

What is the solubility of KNO3 at 40 degrees Celsius?

Back

65 grams per 100 grams of water.

Front

Which solute's solubility does not increase with temperature?

Back

Ammonia (NH3) is an example of a solute that does not increase in solubility as temperature rises.

Front

What is the least soluble solute at 90 °C among SO2, KClO3, KI, and HCl?

Back

SO2 is the least soluble at 90 °C.

Front

What effect does heating a solution have on solubility?

Back

Heating a solution allows for more solute to dissolve than at lower temperatures.

Front

Which of the following is most likely a gas: KNO3, NaNO3, KCl, or Ce2(SO4)3?

Back

Ce2(SO4)3 is most likely a gas.

Front

What is the general trend of solubility for gases as temperature increases?

Back

The solubility of gases generally decreases as temperature increases.

Front

What is the effect of pressure on the solubility of gases?

Back

Increasing pressure increases the solubility of gases in liquids.
