  • question_answer
    A weak monoprotic acid of 0.1 M, ionizes to 1% in solution. What will be the pH of solution          [MNR 1988]

    A)                 1             

    B)                 2

    C)                 3             

    D)                 11

    Correct Answer: C

    Solution :

               \[[{{H}^{+}}]=C\,.\,\alpha \]            \[[{{H}^{+}}]=0.1\times \frac{1}{100}={{10}^{-3}}\]                                 pH\[=-\log \,\,[{{H}^{+}}]=-\log \,{{10}^{-3}}=3\]
