The colligative properties of a solution are related to the

  • (A)  pH of the solution.
  • (B)  number of ions in the solution.
  • (C)  total number of solute particles in the solution.
  • (D)  number of un-ionized molecules in the solution.
  • (E)  pKa of the solution.

Answer

(C) Total number of solute particles in the solution

Explanation:

  • Colligative properties (like osmotic pressure, boiling point rise, freezing point drop) depend on how many particles are in solution, not what they are.
  • More solute particles = greater effect

So, the correct answer is C — it’s all about the total particle count, ioniz
