Question 2
adding more solute to a solvent
a)decreases its boiling point
b)does not affect its boiling point
c)increases its boiling point
d)increases its freezing point

C) Increases its boiling point

Explanation:

Adding more solute to a solvent increases its boiling point! This is a phenomenon described by the colligative properties. When we add a solvent to a solute, the boiling point increases.

Put in vapor pressure terms, a liquid boils at the temperature when its vapor pressure equals the surrounding pressure. For the solvent, the presence of the solute decreases its vapor pressure by dilution. Thus, a higher temperature is needed for the vapor pressure to reach the surrounding pressure, and the boiling point is elevated.
