  • question_answer
    \[pH\] value of \[N/10\,\,NaOH\] solution is [CBSE PMT 1996;Pb. CET 2001; Pb. PMT 2002]

    A)                 10          

    B)                 11

    C)                 12          

    D)                 13

    Correct Answer: D

    Solution :

               In \[\frac{N}{10}\]NaOH have \[[O{{H}^{-}}]={{10}^{-1}}\]M means \[pOH=1\] and then \[pH+pOH=14\]                     \[pH=14-pOH=13\].
