    Which of the following \[{{K}_{a}}\] values, represents the strongest acid?

    A)  \[{{10}^{-4}}\]                 

    B)         \[{{10}^{-8}}\]                 

    C)  \[{{10}^{-5}}\]                 

    D)         \[{{10}^{-2}}\]

    Correct Answer: D

    Solution :

    Larger the \[{{K}_{a}}\] (dissociation constant) of an acid, more will be the \[{{H}^{+}}\] ions produced, hence, stronger will be the acid. Hence,\[{{K}_{a}}={{10}^{-2}}\] represents the strongest acid.
