(Savvas 8.2) Ch 8.2 Solubility and Concentration

What is solubility?

• Solubility is a measure of the ability of a substance to dissolve in a solvent.

• Solubility is the process of a solid turning into a gas.

• Solubility is a measure of the ability of a substance to conduct electricity.

• Solubility is the process of a liquid freezing into a solid.

A solution that has less than the maximum amount of solute that can be dissolved is called a(n) ________________.

• unsaturated solution

• saturated solution

• supersaturated solution

• colloidal solution

Is the following sentence true or false? It is impossible for a solution to contain more solute than the solvent can hold at a given temperature.

• True

• False

Which factors affect the solubility of a solute? (Mark all that apply.)

• polarity of the solvent

• amount of solvent

• pressure

• temperature

What is a common guideline for predicting solubility?

• Like dissolves like.

• Opposites attract.

• All solids dissolve in water.

• Solubility is independent of polarity.

In general, the solubility of a solid increases as the solvent temperature ____________.

• increases

• decreases

• remains constant

In general, the solubility of a gas increases as the solvent temperature ____________.

• increases

• decreases

• remains constant

In general, the solubility of a gas increases as pressure ____________.

• increases

• decreases

• remains constant

• fluctuates

What does the concentration of a solution refer to?

• The amount of solute dissolved in a given amount of solvent or solution.

• The temperature at which a solution boils.

• The color of the solution.

• The pressure exerted by the solution.

This solution would be considered
