    Which one of the following solutions will have highest conductivity?

    A) \[0.1\,M\,C{{H}_{3}}COOH\]

    B) \[0.1\,M\,NaCl\]

    C) \[0.1\,M\,KN{{O}_{3}}\]

    D) \[0.1\,M\,HCl\]

    Correct Answer: D

    Solution :

    \[NaCl,\text{ }KN{{O}_{3}},HCl\] are strong electrolytes but the size of H+ is smallest. Smaller the size of the ions, greater is the conductance and hence greater is the conductivity (k = C \[\times \] cell const).
