Question

When a nonvolatile solute is added to a volatile solvent, the solution vapor pressure __________, the boiling point __________, the freezing point __________, and the osmotic pressure across a semipermeable membrane __________.

a) decreases, increases. decreases, increases
b) increases, increases, decreases, increases
c) increases, decreases, increases, decreases
d) decreases, decreases, increases, decreases
e) decreases; increases. decreases. decreases

Answer 1

C

Step-by-step explanation:

When the nonvolatile solute mixes with the volatile solvent, the resulting solution becomes denser this leads to a decrease in the vapor pressure of the solution, increase in the boiling points of the solution, decrease in it freezing point and an increase in the osmotic pressure across a semipermeable membrane
