Unit 6 Solutions Test Review

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 an aqueous solution?

Back

A solution in which water is the solvent.

Front

True or False: The higher the concentration of a solution, the less solutes it has in it.

Back

False. A higher concentration means more solutes are present.

Front

How do you calculate the number of moles in a solution?

Back

Moles = Molarity (M) x Volume (L). For example, 0.465 M x 0.045 L = 0.0209 mol.

Front

What action increases the rate of solubility of a solute in a solvent?

Back

Stirring the solute in the solution increases the rate of solubility.

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 a supersaturated solution?

Back

A solution that contains more solute than it can theoretically hold at a given temperature.

Front

What is the definition of solubility?

Back

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

Front

What factors affect the solubility of a solute?

Back

Temperature, pressure, and the nature of the solute and solvent.

Front

What is molarity?

Back

Molarity (M) is a measure of concentration, defined as moles of solute per liter of solution.
