    A weak acid is 0.1% ionised in 0.1 K solution. Its pH is:

    A)  2                                            

    B)  3

    C)  4                                            

    D)  1

    Correct Answer: C

    Solution :

                    Given, that \[C=0.1\text{ }M\] \[\alpha =0.1%=0.001\] \[\therefore \]  \[[{{H}^{+}}]=C.\alpha =0.1\times 0.001\]                 \[=1.0\times {{10}^{-4}}\] \[\therefore \]  \[pH=-\log [{{H}^{+}}]\]                 \[=-\log {{10}^{-4}}\]                 \[=4\]
