Solubility

Front

What is solubility?

Back

The ability of a substance (solute) to dissolve in a solvent at a given temperature and pressure.

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 an unsaturated solution?

Back

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

Front

What is a supersaturated solution?

Back

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

Front

What is an electrolyte?

Back

A compound that dissociates in water to form ions, allowing the solution to conduct electricity.

Front

What is a nonelectrolyte?

Back

A substance that does not dissociate into ions in solution and does not conduct electricity.

Front

How does temperature affect solubility?

Back

Generally, solubility of solids increases with temperature, while the solubility of gases decreases.

Front

What is the role of pressure in gas solubility?

Back

Increasing pressure increases the solubility of gases in liquids.

Front

What is the difference between a homogeneous and heterogeneous solution?

Back

A homogeneous solution has a uniform composition, while a heterogeneous solution has distinct, separate phases.

Front

What is the formula for calculating solubility?

Back

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