    Which one of the following solutions will have highest conductivity?

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

    B)  \[0.1\text{ }M\text{ }NaCl\]

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

    D)  \[0.1\text{ }M\text{ }HCl\]

    Correct Answer: D

    Solution :

     \[NaCl,\text{ }KN{{O}_{3}},\text{ }HCl\]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.)
