  • question_answer
    Highest pH 14 is given by              [DCE 1999]

    A)                 \[0.1\,M\,{{H}_{2}}S{{O}_{4}}\]

    B)                 \[0.1\,M\,NaOH\]

    C)                 \[1N\,NaOH\]   

    D)                 \[1N\,HCl\]

    Correct Answer: C

    Solution :

               1N \[NaOH\]solution have highest pH                    \[[O{{H}^{-}}]=1;\,\,pOH=0\];\[pH+pOH=14\]                                 \[pH=14-0=14\]
