    The solubility product of a binary weak electrolyte is \[4\times {{10}^{-10}}\]at\[298K\]. Its solubility in  \[mol\text{ }d{{m}^{-3}}\]at the same temperature is:

    A)  \[4\times {{10}^{-5}}\]

    B)  \[2\times {{10}^{-5}}\]

    C)  \[8\times {{10}^{-10}}\]

    D)  \[16\times {{10}^{-20}}\]

    Correct Answer: B

    Solution :

    The solubility product of a binary weak electrolyte \[=4\times {{10}^{-10}}\] \[\therefore \]  Solubility \[=\sqrt{4\times {{10}^{-10}}}\] \[=2\times {{10}^{-5}}\]
