Solutions and dissolving

Front

What is a saturated solution?

Back

A saturated solution is one that contains as much solute as it can hold at a given temperature and pressure.

Front

How can you make a solution more concentrated?

Back

You can make a solution more concentrated by adding more solute.

Front

What is a solvent?

Back

A solvent is the substance that does the dissolving in a solution.

Front

What is a solute?

Back

A solute is the substance that is being dissolved in a solution.

Front

What does it mean to dilute a solution?

Back

To dilute a solution means to lower the concentration of solute per unit of solvent.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute at a given temperature and pressure.

Front

What is a supersaturated solution?

Back

A supersaturated solution is one that contains more solute than it can normally hold at a given temperature.

Front

What happens when you add water to a concentrated solution?

Back

Adding water to a concentrated solution dilutes it, lowering the concentration of solute.

Front

What is the role of temperature in solubility?

Back

Temperature can affect solubility; generally, higher temperatures increase the solubility of solids in liquids.

Front

What is the difference between a homogeneous and heterogeneous mixture?

Back

A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has a non-uniform composition.
