Chemical Solutions

Front

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 dissolves in a solvent to form a solution.

Front

What is a solvent?

Back

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

Front

What is an unsaturated solution?

Back

A solution that contains less solute than it has the capacity to dissolve at a given temperature.

Front

What is a saturated solution?

Back

A solution that contains the maximum amount of solute that can dissolve at a given temperature.

Front

What is the effect of temperature on the solubility of solids?

Back

Increasing temperature generally increases the solubility of solids in liquids.

Front

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

Back

Increasing temperature generally decreases the solubility of gases in liquids.

Front

What happens to the energy of particles when a solvent is heated?

Back

The energy of the particles increases, causing them to move faster.

Front

How does heating a solvent affect the rate of dissolution of a solid solute?

Back

Heating a solvent increases the rate at which a solid solute can dissolve.

Front

What is a concentrated solution?

Back

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