    When a solution of sodium hydroxide is added to acetic acid solution, the conductivity of the resulting solution will

    A)  increase          

    B)  remain unchanged

    C)  decrease          

    D)  become zero

    Correct Answer: A

    Solution :

     Increase because\[\text{NaOH}\]is strong base and \[\text{C}{{\text{H}}_{\text{3}}}\text{COOH}\]is weak acid, when mixed then the salt formation takes place, i.e., \[\text{C}{{\text{H}}_{\text{3}}}\text{COONa}\text{.}\]Salt increases the conductivity.
