Reading 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 unsaturated?

Back

It means that more solute can still be dissolved in the solution.

Front

What is the solubility of KNO3 at 40 degrees Celsius?

Back

KNO3 is less soluble than NH4Cl at this temperature.

Front

Which solute is more soluble at 10 degrees Celsius: KI or NH4Cl?

Back

KI is more soluble at 10 degrees Celsius.

Front

What is the definition of a saturated solution?

Back

A solution in which no more solute can dissolve at a given temperature.

Front

What happens to the solubility of most solids as temperature increases?

Back

The solubility of most solids increases with an increase in temperature.

Front

What is the solubility of gases in relation to temperature?

Back

The solubility of gases generally decreases as temperature increases.

Front

What is an example of a gas that is soluble in water?

Back

Ammonia (NH3) is an example of a gas that is soluble in water.

Front

What does it mean if a solution is concentrated?

Back

It means that the solution contains a large amount of solute relative to the amount of solvent.

Front

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

Back

Increasing pressure increases the solubility of gases in liquids.
