    The values of dissociation constants of some acids (at \[{{25}^{o}}C\]) are as follows. Indicate which is the trongest acid in water                                      [MP PMT 1991]

    A)                 \[1.4\times {{10}^{-2}}\]              

    B)                 \[1.6\times {{10}^{-4}}\]

    C)                 \[4.4\times {{10}^{-10}}\]            

    D)                 \[4.3\times {{10}^{-7}}\]

    Correct Answer: A

    Solution :

                    More is \[{{K}_{a}}\], lesser is \[p{{K}_{a}}\,(p{{K}_{a}}=-\log {{K}_{a}})\] more is acidic strength.
