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

  • question_answer
    The hydrogen ion concentration in a given solution is \[6\times {{10}^{-4}}.\] Its \[pH\] will be    [EAMCET 1978]

    A)                 6             

    B)                 4

    C)                 3.22       

    D)                 2

    Correct Answer: C

    Solution :

               \[[{{H}^{+}}]=6\times {{10}^{-4}}\]M                                 \[pH=-\log \,\,[{{H}^{+}}]\] \[=-\log \,\,[6\times {{10}^{-4}}]=3.22\].
