Mixtures, Solutions & Solubility Curves

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically bonded together.

Front

What is a solution?

Back

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

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent at a given temperature and pressure.

Front

How does temperature affect solubility?

Back

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

Front

What is a solubility curve?

Back

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

Front

What happens to the kinetic energy of particles when temperature increases?

Back

The kinetic energy of particles increases, leading to more frequent and energetic collisions.

Front

What is the effect of stirring on solubility?

Back

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

Front

What is the least soluble solute at 0 ºC in a given solubility curve?

Back

The solute that shows the lowest point on the curve at 0 ºC.

Front

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

Back

Generally, the solubility of gases decreases as temperature increases.

Front

What is a saturated solution?

Back

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