    Which of the following solutions in water will have the lowest vapour pressure          [Roorkee 2000]

    A)                 0.1 M, NaCl          

    B)                 0.1 M, Sucrose

    C)                 0.1 M, \[BaC{{l}_{2}}\]      

    D)             0.1 M  \[N{{a}_{3}}P{{O}_{4}}\]

    Correct Answer: D

    Solution :

             \[N{{a}_{3}}P{{O}_{4}}\]consist of maximum ions hence it show lowest vapour pressure.                 \[N{{a}_{3}}P{{O}_{4}}\to 3N{{a}^{+}}+PO_{4}^{3-}=4\]ion.
