    The\[pH\]of a solution is increased from 3 to 6, its\[{{H}^{+}}\]ion concentration will be

    A)  reduced to half

    B)                         doubled

    C)                         reduced by 1000 times

    D)                         increased by 1000 times

    Correct Answer: C

    Solution :

    When\[pH=3\]then\[[{{H}^{+}}]={{10}^{-3}}\]. After that we increased the\[pH\]from 3 to 6 then\[[{{H}^{+}}]={{10}^{-6}}M\]means reduced 1000 times.
