  • question_answer
    A litre of solution is saturated with\[AgCl\]. To this solution if \[1.0\times {{10}^{-4}}\]mole of solid \[NaCI\]is added, what will be the \[[A{{g}^{+}}],\] assuming no volume change?

    A) More               

    B)        Less

    C) Equal               

    D)        Zero

    Correct Answer: B

    Solution :

    The dissociation of a weak electrolyte \[(AgCl)\] is sup-pressed on adding the strong electrolyte having a common ion \[(C{{l}^{-}}),\] hence concentration of \[A{{g}^{+}}\] ion will be less.
