Solutions and matter H review

Front

What is the definition of solubility?

Back

Solubility is the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure.

How do you calculate solubility in g per 100 g of water?

Back

Solubility (g/100 g water) = (mass of solute (g) / mass of solvent (g)) x 100.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution.

Front

What is a solution?

Back

A solution is a homogeneous mixture of two or more substances, where the solute is uniformly distributed within the solvent.

Front

What is an example of a solid solution?

Back

Bronze is an example of a solid solution, consisting of copper and tin.

Front

What is the difference between a saturated and an unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, while an unsaturated solution can still dissolve more solute.

Front

What is the significance of temperature in solubility?

Back

Temperature affects solubility; generally, solubility of solids increases with temperature, while the solubility of gases decreases.

Front

What is the role of pressure in the solubility of gases?

Back

Increasing pressure increases the solubility of gases in liquids, as described by Henry's Law.

Front

What is an example of a gaseous solution?

Back

Air is an example of a gaseous solution, primarily composed of nitrogen and oxygen.
