What is a solution?

Back

A homogeneous mixture of two or more substances where one substance (solute) is dissolved in another (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 does the dissolving in a solution.

Front

What is a homogeneous mixture?

Back

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

Front

What is a concentrated solution?

Back

A solution that contains a large amount of solute relative to the amount of solvent.

Front

What is a diluted solution?

Back

A solution that contains a small amount of solute relative to the amount of solvent.

Front

How can the rate of dissolution be increased?

Back

By stirring the mixture, increasing temperature, or increasing surface area of the solute.

Front

What happens to the solubility of most solids as temperature increases?

Back

The solubility of most solids increases with an increase in temperature.

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 saturation in a solution?

Back

A point at which no more solute can dissolve in the solvent at a given temperature and pressure.
