JEE Main & Advanced Chemistry Equilibrium / साम्यावस्था Question Bank Hydrogenion concentration pH scale and buffer solution

  • question_answer
    The \[pH\]of a solution is increased from 3 to 6. Its \[{{H}^{+}}\]ion concentration will be              [EAMCET 1998]

    A)                 Reduced to half

    B)                 Doubled

    C)                 Reduced by 1000 times

    D)                 Increased by 1000 times

    Correct Answer: C

    Solution :

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