    How many times a solution of \[pH=2\]has higher acidity than the solution of \[pH=6\]

    A)  \[4\]                                    

    B)  \[12\]

    C)  \[400\]                

    D)         \[10000\]

    Correct Answer: D

    Solution :

    In a solution of \[pH=2,[{{H}^{+}}]={{10}^{-2}}M\] In a solution of \[pH=6,[{{H}^{+}}]={{10}^{-6}}M\] Ratio of \[[{{H}^{+}}]\] in two solutions                 \[=\frac{{{10}^{-2}}M}{{{10}^{-6}}M}={{10}^{4}}=10,000\]
