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

  • question_answer
    The \[{{H}^{+}}\]ion concentration is \[1.0\times {{10}^{-6}}\] mole/litre in a solution. Its pH value will be [MP PMT 1985; AFMC 1982]

    A)                 12          

    B)                 6

    C)                 18          

    D)                 24

    Correct Answer: B

    Solution :

               \[[{{H}^{+}}]=1.00\times {{10}^{-6}}\] mole/litre                 \[pH=-\,\log \,\,[1.00\times {{10}^{-6}}]\]; pH = 6.
