Which of the following are the conditions of colligative properties_______________?
Correct answer: D. All of the above
- A. Non-electrolye solute
- B. Non-volatile solute
- C. Dilute solution
- D. All of the above
Explanation
In the usual introductory treatment, colligative-property calculations use a dilute solution containing a non-volatile, non-electrolyte solute, so the intended choice is all of the above. A student may choose b because non-volatility is the key condition, but this ignores the stated dilute and non-electrolyte conditions used for the simple formulas.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
