Mixtures, Solutions & Solubility Curves

Front

What is a heterogeneous mixture?

Back

A mixture where the components do not mix uniformly and can be easily distinguished from one another.

Front

What is a homogeneous mixture?

Back

A mixture that has a uniform composition throughout, where the individual components are not distinguishable.

Front

What is a solution?

Back

A homogeneous mixture formed when a solute is dissolved in a solvent.

Front

What is a solute?

Back

The substance that is being dissolved in a solution.

Front

What is a solvent?

Back

The substance that dissolves the solute in a solution.

Front

Define solubility.

Back

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

Front

What factors affect the rate of solubility?

Back

Temperature, stirring, and surface area of the solute.

Front

How does temperature affect solubility?

Back

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

Front

What is a solubility curve?

Back

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

Front

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

Back

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