    The pH of an aqueous solution having hydroxide ion concentration as\[1\times {{10}^{-5}}\]is:

    A)  5                                            

    B)  9

    C)  4.5                                        

    D)  11

    Correct Answer: B

    Solution :

                    \[[O{{H}^{-}}]=1\times {{10}^{-5}}\] \[pOH=-log[O{{H}^{-}}]\] \[=-\log [1\times {{10}^{-5}}]\] \[pOH=5\] \[pH+pOH=14\] \[pH=14-pOH\] \[=14-5\] \[pH=9\]
