    The\[{{K}_{w}}\]for autoprotolysis of water at 298K \[2{{H}_{2}}{{O}_{(l)}}\rightleftharpoons {{H}_{3}}{{O}^{+}}_{(aq)}+O{{H}^{-}}_{(aq)}\]is

    A)  \[{{10}^{-14}}mo{{l}^{2}}{{L}^{-2}}\]

    B)  \[{{10}^{-14}}mo{{l}^{-1}}{{L}^{-1}}\]

    C)  \[{{10}^{-4}}mol{{L}^{-1}}\]

    D)  \[{{10}^{-4}}mo{{l}^{2}}{{L}^{-1}}\]

    Correct Answer: A

    Solution :

    : \[{{K}_{w}}=[O{{H}^{-}}][{{H}_{3}}{{O}^{+}}]={{10}^{-14}}mo{{l}^{2}}{{L}^{-2}}\]
