Question

Colligative properties include __________ the freezing point, _____________ the vapor pressure, and ___________ the boiling point. Which of the following sequences of words correctly fills in the blanks?

a) raising, lowering, loweringb) raising, raising, loweringc) lowering, raising, lowering d) lowering, lowering, raising

Answer 1

Colligative properties include lowering the freezing point, lowering the vapor pressure, and raising the boiling point.

Answer 2

The answer is: d) lowering, lowering, raising.

The vapor pressure depression (lowering), freezing point depression (lowering) and the boiling point elevation (raising) are the colligative properties od solution.

For example pure water has lower boiling point than solution of water and some salt.

The higher is the molarity of the solution, the lower is freezing point.
