Question

The statements in the following multiple choices deal with the relationship between solute concentration and various colligative properties. Choose the statement which is true.



a) Decreasing the concentration of a nonvolatile solute in water decreases the freezing point of the solution.
b) Increasing the concentration of a nonvolatile solute in water increases the osmotic pressure of the solution.
c) Decreasing the concentration of a nonvolatile solute in water increases the boiling point of the solution.
d) Increasing the concentration of a nonvolatile solute in water increases the freezing point of the solution.
e) Increasing the concentration of a nonvolatile solute in water decreases the osmotic pressure of the solution.

Explanation / Answer

b) Increasing the concentration of a nonvolatile solute in water increases the osmotic pressure of the solution. note: p = cRT osmotic pressure is positively proportional to molar concentration (C) of solute.
