Mixtures, Solutions & Solubility Curves

Front

What is a mixture?

Back

A combination of two or more substances that are not chemically bonded.

Front

What is a solution?

Back

A homogeneous mixture where one substance (solute) is dissolved in another (solvent).

Front

What is solubility?

Back

The amount of solute that can dissolve in a given amount of solvent at a specific temperature.

Front

What is a solubility curve?

Back

A graph that shows the relationship between solubility and temperature for a specific solute.

Front

Which substance is typically a solvent?

Back

Water is the most common solvent.

Front

How does temperature affect solubility?

Back

Generally, as temperature increases, the solubility of solids in liquids increases.

Front

What happens to the solubility of gases in liquids as temperature increases?

Back

The solubility of gases in liquids typically decreases as temperature increases.

Front

What is the difference between a saturated solution and an unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, while an unsaturated solution can still dissolve more solute.

Front

What is an example of a solute?

Back

Sugar is an example of a solute when dissolved in water.

Front

What is the effect of stirring on the rate of solubility?

Back

Stirring increases the rate at which a solute dissolves in a solvent.
