Mixtures, Solutions & Solubility Curves

Front

What is a mixture?

Back

A combination of two or more substances that are not chemically bonded and can be separated by physical means.

Front

What is a solution?

Back

A homogeneous mixture where one substance (solute) is dissolved 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 is a solubility curve?

Back

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

Front

What happens to solubility as temperature increases?

Back

For most solids, solubility increases as temperature increases.

Front

What is a heterogeneous mixture?

Back

A mixture where the components are not uniform and can be easily distinguished.

Front

What is a homogeneous mixture?

Back

A mixture that has a uniform composition throughout, such as a solution.

Front

What is a solute?

Back

The substance that is being dissolved in a solution.

Front

What is a solvent?

Back

The substance in which the solute is dissolved, usually present in greater amount.

Front

What factors affect the rate of dissolution?

Back

Stirring, temperature, and surface area of the solute can increase the rate of dissolution.
