Mixtures, Solutions & Solubility Curves CP

Front

What is a heterogeneous mixture?

Back

A mixture where the components are not uniformly distributed 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 one substance (solute) dissolves in another (solvent).

Front

What is solubility?

Back

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

Front

What does a solubility curve represent?

Back

A graph that shows the relationship between the solubility of a substance and temperature.

Front

How does temperature affect solubility?

Back

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

Front

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

Back

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

Front

What happens to solubility when temperature decreases?

Back

For most solids, solubility decreases as temperature decreases.

Front

What is the role of surface area in dissolution?

Back

Increasing the surface area of a solute increases the rate of dissolution.

Front

What is an example of a mixture?

Back

A salad is an example of a mixture, as its components can be seen and separated.
