    The \[pH\] of 0.1 M solution of a weak monoprotic acid 1% ionized is      [UPSEAT 2001; Pb. PMT 2001]

    A)                 1             

    B)                 2

    C)                 3             

    D)                 4

    Correct Answer: C

    Solution :

               \[C=0.1M;\,\,\,\,\alpha =1%;\,\,\,\,({{H}^{+}})=C\times \alpha \]                                 \[=0.1\times \frac{1}{100}={{10}^{-3}}\]; \[({{H}^{+}})={{10}^{-3}}\]; pH = 3.
