Solutions and dissolving

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 is dissolved in a solution.

Front

What is a solvent?

Back

The substance in which the solute is dissolved to form a solution.

Front

What does concentration refer to in a solution?

Back

The amount of solute present in a given volume of solvent or solution.

Front

What is a saturated solution?

Back

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

Front

What does it mean to dilute a solution?

Back

To decrease the concentration of solute in a solution by adding more solvent.

Front

What is the difference between a concentrated solution and a dilute solution?

Back

A concentrated solution has a high amount of solute relative to the solvent, while a dilute solution has a low amount of solute relative to the solvent.

Front

What is the role of temperature in solubility?

Back

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

Front

What is the formula for calculating concentration?

Back

Concentration = Amount of solute (in grams) / Volume of solution (in liters).

Front

What is a supersaturated solution?

Back

A solution that contains more solute than can normally be dissolved at a given temperature.
