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 does solubility mean?

Back

The ability of a solute to dissolve in a solvent, usually expressed in grams of solute per 100 grams of solvent.

Front

What happens to solubility as temperature increases?

Back

Generally, solubility of solids in liquids increases with temperature.

Front

What is a heterogeneous mixture?

Back

A mixture that has a non-uniform composition and the different components can be seen.

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 solubility curve?

Back

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

Front

How can you increase the rate of solubility?

Back

By stirring the solution, increasing temperature, or decreasing the particle size of the solute.

Front

What is the effect of pressure on the solubility of gases?

Back

Increasing pressure increases the solubility of gases in liquids.

Front

What is the difference between solute and solvent?

Back

The solute is the substance that is dissolved, while the solvent is the substance that does the dissolving.
