    Which of the following solutions will have the highest boiling point?

    A)  1 M glucose solution

    B)  1 M sodium nitrate solution

    C)  1 M barium chloride solution

    D)  1 M aluminium chloride solution

    Correct Answer: D

    Solution :

     \[1\text{ }M\text{ }AlC{{l}_{3}}\]solution will have the highest boiling point is because colligative properties such as elevation in boiling point is directly proportional to number of particles in solutions and\[AlC{{l}_{3}}\]produces highest number of particles or ions. (i.e.,\[AlC{{l}_{3}}=1+3=4\]).
