    Which of the following solutions will exhibit highest boiling point?

    A)  \[0.01\,M\,N{{a}_{2}}S{{O}_{4}}(aq)\]

    B)  \[0.01\,M\,KN{{O}_{3}}(aq)\]

    C)  \[0.015\,M\,urea\,(aq)\]

    D)  \[0.015\,M\,glu\cos e\,(aq)\]

    Correct Answer: A

    Solution :

                    Molecules having maximum number of ions will have maximum value of boiling point. In the given options, 0.01 M\[N{{a}_{2}}S{{O}_{4}}\] contains maximum number of ions. So, 0.01 M\[N{{a}_{2}}S{{O}_{4}}\] has highest boiling point.
