  • question_answer
    The \[pH\]value of \[0.1\,\,M\,\,HCl\]is approximately 1. What will be the approximate \[pH\]value of 0.05 \[M\,\,{{H}_{2}}S{{O}_{4}}\] [MP PMT 1991]

    A)                 0.05       

    B)                 0.5

    C)                 1             

    D)                 2

    Correct Answer: C

    Solution :

               \[{{H}_{2}}S{{O}_{4}}=0.05\times 2\]                                 \[\therefore \,[{{H}^{+}}]=0.1\] and \[pH=1\]
