Ch. 27 - Concentrations of Solutions

What does the concentration of a solution tell you?

The amount of solute that i

What is molarity?

The number of moles of a solute dissolved in a solution

What is molality?

The number of moles of a solute dissolved in a solvent

What is a colligative property?

A physical property of a solution that depends on the ratio of the amount of solute to the solvent, not the type of solvent

Which is dependent on temperature: molarity or molality?

Molarity

What happens to molarity when temperature increases?

The volume increases

What are some colligative properties?

Freezing point depression, boiling point depression and vapor-pressure reduction

What happens to a solvent when a solute is added to it?

Its vapor pressure reduces

When does dilution occur?

When more solvent is added to a fixed amount of solute
