Question

The colligative properties of a solution are:

• A. $\propto molality$
• B. $\propto 1/M$
• C. dependent on nature of species
  
• D. none of the above

Answer 1

Answer: (A), (B)

The correct options are
A $\propto molality$
B $\propto 1/M$

Colligative properties are properties of solutions that depend upon the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the type of chemical species present.It means colligative properties depends on molality.Hence options A, B are correct.
