  • question_answer
    If the \[pH\] of a solution is 2, its normality will be [MADT Bihar 1982; MP PET 2000]

    A)                 2N         

    B)                 \[\tfrac{1}{2}N\]

    C)                 0.01 N  

    D)                 None of these

    Correct Answer: C

    Solution :

               \[pH=2\] ; \[pH=-\log \,\,[{{H}^{+}}]\] ; \[2=-\log \,\,\,[{{H}^{+}}]\]                                 \[[{{H}^{+}}]={{10}^{-2}}=0.01\,N\]
