CFU 6.5 Colligative Properties (Flashcardizz. 12-16)

Front

What are colligative properties?

Back

Colligative properties are properties of solutions that depend on the number of solute particles in a given amount of solvent, not on the identity of the solute.

Front

How do electrolytes differ from nonelectrolytes in terms of colligative properties?

Back

Electrolytes produce more moles of solute particles per mole of solvent compared to nonelectrolytes, which enhances their effect on colligative properties.

Front

What is an example of a mixture?

Back

Air is an example of a mixture, as it contains various gases mixed together.

Front

Why can't a solution be separated by filtration?

Back

A solution cannot be separated by filtration because the solute particles are too small and pass through the filter.

Front

What happens to the boiling point of a solution compared to the pure solvent?

Back

The boiling point of a solution is higher than the boiling point of the pure solvent.

Front

What is the effect of adding a solute to a solvent on its freezing point?

Back

Adding a solute to a solvent lowers the freezing point of the solution compared to the pure solvent.

Front

Define the term 'solute'.

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

Define the term 'solvent'.

Back

A solvent is a substance that dissolves a solute, resulting in a solution.

Front

What is the van 't Hoff factor (i)?

Back

The van 't Hoff factor (i) is the number of particles into which a solute dissociates in solution.

Front

How does the presence of a non-volatile solute affect vapor pressure?

Back

The presence of a non-volatile solute lowers the vapor pressure of the solvent.
