Solubility

Front

What is solubility?

Back

The ability of a substance (solute) to dissolve in a solvent at a given temperature and pressure.

Front

What is an unsaturated solution?

Back

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

Front

What is a saturated solution?

Back

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

Front

What is a supersaturated solution?

Back

A solution that contains more solute than can normally dissolve at a given temperature.

Front

What factors affect solubility?

Back

Temperature, pressure, and the nature of the solute and solvent.

Front

What is the solubility curve?

Back

A graph that shows the amount of solute that can be dissolved in a solvent at various temperatures.

Front

Which substance is most soluble at 0 ºC: KI, NaNO3, NaCl, or Ce2(SO4)3?

Back

NaNO3.

Front

How does agitation affect solubility?

Back

Agitating the solution usually increases the rate at which a solute dissolves.

Front

What is the effect of temperature on solubility for most solids?

Back

For most solids, solubility increases with an increase in temperature.

Front

What is the effect of temperature on solubility for gases?

Back

For gases, solubility typically decreases with an increase in temperature.
