D) lower vapor pressure, lower boiling point and higher freezing point

Question

Quizplus · Accepted Answer

When a solute is added to a solvent, the vapor pressure decreases, causing a lower boiling point and a lower freezing point. This is known as a colligative property. So, a 1 M sugar-water solution will have a lower vapor pressure, higher boiling point, and lower freezing point compared to pure water.
