    For triple the pH of a solution the concentration of hydrogen ion should be:

    A)  \[1/100\text{ }times\]                 

    B)                         half

    C)                         double                                

    D)                         \[1/1000\text{ }times\]

    Correct Answer: D

    Solution :

    If \[pH=1\], then \[[{{H}^{+}}]\,\,{{10}^{-1}}\] If             \[pH=3\] then      \[[{{H}^{+}}]={{10}^{-3}}\]                 \[[{{H}^{+}}]=\frac{1}{1000}times\]
