Solutions Review

Front

What is the definition of concentration in a solution?

Back

Concentration refers to the amount of solute present in a given quantity of solvent or solution, often expressed in terms of molarity, mass percent, or volume percent.

Front

How can the concentration of a mixture be increased?

Back

The concentration of a mixture can be increased by adding more solute.

Front

What is a saturated solution?

Back

A saturated solution is one that contains the maximum amount of dissolved solute at a given temperature and pressure.

Front

What does it mean if a solution is unsaturated?

Back

An unsaturated solution is one that contains less solute than the maximum amount that can be dissolved at a given temperature.

Front

What is a supersaturated solution?

Back

A supersaturated solution is one that contains more solute than can normally be dissolved at a given temperature, often achieved by heating the solution and then cooling it.

Front

How does temperature affect the solubility of gases?

Back

Gases are more soluble in liquids at low temperatures.

Front

How does pressure affect the solubility of gases?

Back

Gases are more soluble in liquids at high pressures.

Front

What happens to the solubility of solids in liquids as temperature increases?

Back

The solubility of most solids in liquids increases as the temperature increases.

Front

What is the effect of stirring on the rate of dissolving?

Back

Stirring increases the rate of dissolving by distributing solute particles throughout the solvent more quickly.

Front

What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved in a solution, while a solvent is the substance that dissolves the solute.
