Physical Properties & Solutions

Front

What is a supersaturated solution?

Back

A supersaturated solution is a solution that contains more solute than it can theoretically hold at a given temperature, leading to the potential for crystallization.

Front

What happens when a seed crystal is added to an unsaturated solution?

Back

The seed crystal will dissolve in an unsaturated solution because there is still capacity for more solute to be dissolved.

Front

What factors affect the rate of solubility of a substance in a solvent?

Back

The rate of solubility is affected by temperature, surface area of the solute, and the stirring of the solution.

Front

Why do powdered substances dissolve faster than solid chunks in a solvent?

Back

Powdered substances have a larger surface area exposed to the solvent, allowing for more interactions and faster dissolution.

Front

What is the relationship between temperature and the solubility of gases in liquids?

Back

Generally, the solubility of gases in liquids decreases as the temperature increases.

Front

What conditions favor the solubility of gases in water?

Back

Gases are most soluble in water at low temperatures and high pressures.

Front

What is an unsaturated solution?

Back

An unsaturated solution is a solution that can still dissolve more solute at a given temperature.

Front

What is a saturated solution?

Back

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

Front

How does pressure affect the solubility of solids in liquids?

Back

Pressure has little effect on the solubility of solids in liquids; it primarily affects gases.

Front

What is the effect of stirring on the dissolution process?

Back

Stirring increases the rate of dissolution by distributing solute particles throughout the solvent.
